Installation This chapter focuses on the steps necessary to unpack and install the T-60. Read this section before attempting to apply the T-60. System installers should read this chapter before attempting to install the unit into a cabinet, or before connecting any electrical power to the T-60.
Through Panel Mounting The T-60 is designed to be mounted either through an equipment panel (in a panel cut-out) or on a flat surface. The through-panel mounting will allow the T-60 to meet NEMA4 specifications for water resistance, and will also resist dust, dirt and non corrosive chemicals.

System Interconnect The T-60 is designed to meet a variety of applications; therefore, it is impossible to describe a “standard” interconnect for the T-60.
COM1 and COM2 Connectors COM1 and COM2 are the serial port connectors (DB-9 style, male). The pin-outs for these connectors are as follo ws: These connectors provide connection for serial communications between the T-60 and a variety of devices. Connections made with this connector are most commonly referred to as SERIAL PORTS.
To perform RS485 serial c ommunications with the T-60, the RS422 transmitter and receiver lines must be tied together. Since the RS422 transmitters are disabled after power up, it is safe to assume that no line driver conflicts will occur. Again, refer to the RS422 Statement in the EMERSON EMC BASIC PROGRAMMING GUIDE.
I/O Connector The I/O connector on the T-60 is designed to provide 8 bits of parallel I/O. Each line can be configured in software to perform input, output, or bidirectional operations. The pin-out is an industry standard 20 pin ribbon cable, compatible with industry standard PB-8 boards.
Suppo rt for the T-60’s 8 bit I/O has been provided by the following commands. Some commands refer to 24 bits of I/O instead of 8. This reflects the compatability between the T-60 and the T-61 (the T-61 has 24 bits of I/O standard while the T-60 has 8 bits of I/O).
ApplicationBuilder Included with your T-60 is a disk containing the ApplicationBuilder, a PC program which allows you to quickly generate programs for the T-60. The ApplicationBuilder generates BASIC programs from simple menu selections and direct screen entry of text.
If your system has a hard drive, copy the contents of either of the diskettes onto the hard drive (make a separate directory first for ease of use). If you do not have a hard drive, place the disk labeled DISK 1 into your diskette drive.Log onto the drive with the ApplicationBuilder on it (i.
Simple Example To demonstrate the power of the ApplicationBuilder, a very simple example program will be read from disk, viewed, converted to BASIC, downloaded, and run. Select the FILE menu (ALT-F) and OPEN (move the cursor or type O) followed by ENTER.
Press SOFTKEY F5. This is how you select PSEUDOCODES to place on screen. Type an S. Press ENTER. The SCREEN PSEUDOCODE has been selected. This allows you to type text directly on the screen. Press ESC (leave the program unchanged). Press SOFTKEY F8. This softkey generates BASIC.
4. Are the NULL MODEM cable connectors securely seated into their respective sockets? Try tightening the hold-down screws on the NULL MODEM cable. 5. Are you using the NULL MODEM cable supplied by EMERSON EMC? If not, check the cable for correct configuration.
Builder Mode The Builder Mode is the heart of the ApplicationBuilder package. It allows you to easily develop a control and interface program, test the operator interface functionality of the program, and then generate the proper BASIC code to run in a T-60.
Entering Pseudocode falls into two categories: Entering/placing text on the screen and everything else. Pseudocodes that have nothing to do with text on screen are relatively simple. Each bit of information needed to complete a Pseudocode command is asked for one piece at a time.
Editor Mode Editor Mode is a text editor allowing you to edit files off line from any serial device (such as a T-60.) This allows you to write and modify programs away from your machine and to use more powerful editing features than BASIC has built in.
Terminal Mode The Up and Down cursor keys are not currently functional. If you want to move up or down on the screen, you must do it from the cursor keys on your T-60. If you are editing a line of BASIC, use the EDIT command which will position the cursor on the line you want to change.
Transfer Menu The Transfer menu is used to transfer files back and forth between your T-60 and your PC. You can Download from the PC to the Emerson T-60 or Upload from the product to your PC. You can also Verify whether a program in your interface matches one on your PC or not.
SELECT COM2 - Highlighting COM2 and pressing 07 selects COM2 as the active COM port in your PC for communication with your T-60. Typing “2” while anywhere in the Settings menu will also activate COM2.
Summary of ApplicationBuilder Operation The following is a summary of the sequence of operations required to make a functional program in the ApplicationBuilder (this example assumes you are starting from the DOS prompt with the ApplicationBuilder diskette or hard disk ready).
Operation: Keystroke: Description: Waiting for a softkey Enter Adds the Pseudocode to your program. F5 Select the Pseudocode list. S Move to the “S” section Building more screens: Cursor Move the cursor to the SOFTKEY WAIT Pseudocode. Enter Adds the Pseudocode to your program Cursor Move the cursor to one of the SOFTKEY (skey).
Operation: Keystroke: Description: Run program: F1 (T-60) Run the program on the Model T-60. T-60 Operator's Manual 26.
Screen Editor This Chapter briefly describes the operation of the T-60’s built-in screen editor. For a detailed description of the built-in screen editor, refer to the EMERSON EMC BASIC PROGRAMMING GUIDE. This editor allows the programmer to edit programs directly on the T-60’s screen without a PC attached.
DELETE command erases sections of the program by line number. RENUM allows the entire program or portions of the program to be renumbered. LIST lists all or sections of the program to the screen. LLIST can list all or sections of the program to the printer.
3. FUNCTION keys. Six function keys are active during the help system. These keys perform the following functions: COM1 Displays the buffers and status of COM1. COM2 Displays the buffers and status of COM2 SYS Displays system related status. I/O Displays 8-bit I/O positions and allows the operator to change them.

Application Examples This chapter demonstrates a few of the many applications possible with the T-60. Perhaps the best way to think of the T-60 is as an industrial controller with an integrated operator interface and very capable I/O. In many systems the T-60 can provide the entire system control.
Load and convert SERIAL.BLD into a BASIC file (F8 function). Load it into the T-60. Now, enter the terminal emulator (ALT-M then type T). Press the RUN (F1) softkey on the T-60. You will be asked a question on your PC’s screen. Answer it and press Enter.
When power is tu rned on to the T-60 and the DX Drive, the ApplicationBuilder program will test for communication’s integrity, and begin execution. If the T-60 is unable to establish communications, check the following items: • Verify that the DX Drive Amplifier is on and in working order.
Using The T-60 With One or More DX Drives Connecting the T-60 to the DX drive(s) is very simple when the proper cables are used. The Figure below illustrates the required cables and what they should be connected to. The PC’s COM1 or COM2 is connected to COM2 on the T-60.
DX specific pseudo-commands There are 2 pseudo-commands which are used only with the DX drives: COM: DX PUT COM port TEXT text STRING RESPONSE response COM: DX SELECT AXIS axis These commands are fully described in the builder software and illustrated in the included example programs.

T-60 Basic Programming Language This chapter gives an overview of the capabilities of the EMERSON EMC BASIC. The BASIC language integrated into the T-60 has been custom designed and optimized for speed of execution and ease of use with the specific hardware features of the T-60.
Array Variables An array is a group or table of values referenced by the same variable name. Each element in an array is referenced by an array variable that is a subscripted integer or an integer expression. The subscript is enclosed within parentheses.
Relational Operations Relational operators let you compare two values. The result of the comparison is either true (-1) or false (0). This result can then be used to make a decision regarding program flow.
It is possible to use logical operators to test bytes for a particular bit pattern. For instance, the AND operator may be used to mask all but one of the bits of a status byte at a machine I/O port. The OR operator may be used to merge two bytes to create a particular binary value.
For example: “AA” < “AB” “FILENAME” = “FILENAME” “SMYTH” < “SMYTHE” B$ < “9/12/78” where B$ = “8/12/78” String comparisons can also be used to test string values or to alphabetize strings. All string constants used in comparison expressions must be enclosed in quotation marks.
EMERSON Basic Statements, Commands, and Functions The following is an alphabetized list of statements commands and functions available in the EMERSON EMC BASIC. The EMERSON EMC BASIC PROGRAMMING GUIDE contains a detailed description of the each of these commands.

64K Memory Option The M02 option adds 32K bytes of storage to the T-60’s battery-backed up memory to bring the total memory up to 64K bytes. Larger programs and more data can be stored in this additional memory. In addition, nonvolatile storage registers can also be used when this option is added.
2. Position the front panel to the side of the unit, being careful not to stress the internal cables. 3. To install an MO2 option, insert a 256Kbit RAM (120 nsec, JDEC 32 pin) in location U9. Be sure that PIN 1 (location on RAM with notch or dot) is facing down (towards the center of the unit).
3. To install an MO2 option, insert a 256Kbit RAM (120 nsec, JDEC 32 pin) in location U9. Be sure that PIN 1 (location on RAM with notch or dot) is facing down (towards the center of the unit). Note carefully the position of U9 and the orientation of the RAM in the diagram.
Changing ROMS in the T-60 Follow these steps to change a program ROM in the T-60: 1. Save the contents of the program memory. Use a PC and the ApplicationBuilder program to do this. 2. Remove power connections to the unit. 3. Carefully unscrew the top two screws and each of the screws on the side of the unit.
Changing the Battery in a T-60 Follow these steps to change the battery for the non-volatile RAM in a T-60: 1. Save the contents of the program memory.
9. Replace cover and cover screws. 10. Reconnect power to the unit. 11. If you notice any problems that can’t be explained by the battery being installed upside down (no non-volatile memory), disconnect power and connect an IBM KEYBOARD to the KEYBOARD connector.
Real Time Clock The CLK option adds a battery backed real time clock to the T-60. Once installed you can set the date, day of the week and time with a single statement: CALL WRCLOCK. You can read the day, day of the week, and the time with another single statement: CALL RDCLOCK.
8. Reconnect the backlight cable connector and replace the front panel and screws. 9. It may be necessary to set the real-time clock before it can be used.
Event Driven Software The EMERSON EMC T-60 Event Driven Software allows the T-60 to react quickly to external events, without taxing the overhead of the imbedded BASIC programming language. The Event Software allows the T-60 to scan an input, react to it, and immediately output data to the A/D’s or the 8 bit I/O port.
Event Data Elements: The EVENT SYSTEM is not enabled until the EVENT ON statement is issued. EVENT ON may be used without a corresponding ON EVENT statement, thereby avoiding the use of the T-60’s interrupt system. See the example in the end of this section for the proper use of the EVENT ON syntax.

PLC Interface Commands Introduction The EMERSON EMC T-60 Series PLC Interfaces are designed to make many of the individual intricacies of the various PLC Interfaces transparent to the user. That is to say that reading a register in a Modicon PLC uses the same procedure as reading a register in an Omron PLC.
The tabel below shows the current PLC interface options. As mentioned above, the PLC Interfaces all work in a similar, if not identical, fashion (the -PL5, -SL5, -ID1, -MFX, and -SQD interfaces are more unique than any of the others - refer to the PLC SPECIFIC sections for detailed information on how to use these interfaces).
CALL PLCINIT Statement Purpose: This command is used to initialize communication with a given PLC of a given type. CALL PLCINIT must be issued prior to any other communication (reading or writing) to the specified PLC. CALL PLCINIT does auto-baud rate detect for some PLC’s and sets up specific communications parameters for others.
cmd specifies the type of PLC protocol that you are initiating. This can vary depending upon PLC manufacturer, and possibly model, according to the following ta ble: Examples: 10 CALL PLCINIT(1,1) Est.
CALL PLCREAD Statement Purpose: This command is used to read the value(s) in a PLC’s registers, the status of bits, or any other accessible memory location within the PLC. Refer to the -PL5 and -SL5 for information on how to use this command with the Allen-Bradley PLC-5 and SLC-500 processors.
# of registers/bits is the number of consecutive registers, memory locations, or bits that you wish to read. Most PLC interfaces only allow you to read one at a time, and for many applications that is all you will need to read. If this is the case, # of registers/bits will be 1.
CALL PLCWRITE Statement Purpose: This command is used to write value(s) to a PLC’s register(s), memory location(s), or to force one or more output bits in a PLC. Refer to the -PL5 and -SL5 for information on how to use this command with the Allen-Bradley PLC-5 and SLC-500 processors.
# of registers/bits is the number of consecutive registers, memory locations, or bits that you wish to set. Many PLC Interfaces only allow you to set one at a time, and for many applications that is all you will need to read. If this is the case, # of registers/bits will be 1.
Option PLC’s Supported Protocol Communicate via Com Parameters -MOD Any Modicon PLC Supporting Modbus: Micro 84, 484, 584, 184/384, 884, 984/381, etc.
MOD Interface Option Communications: The -MOD Option communicates via the Modbus protocol. It was developed to allow the T-60 Series to communicate easily to the Modicon PLC’s that use the Modbus protocols (Micro 84, 484, 584, 184/384, 884, 984/381, etc.
GE9 Interface Option Communications: The -GE9 Option uses GE Fanuc’s SNP Protocol to communicate to their Series 90 PLCs. Access to the PLC occurs via the programming port.
TI3 Interface Option Communications: The -TI3 Option uses Texas Instruments’ CCM protocol for communicating to TI Series 305 and Series 405 PLC’s. The Series 305 PLC’s (Models 315, 325, and 330) communicate via a DCU module. The communication parameters are auto-detected by the T-60 Series device.
Command Variations: TI Series 305 and 405 PLC’s return 5 words of network status information when using CALL PLCREAD with cmd = 1. The following example describes a typical way to read the status in.
TI5 Interface Option Communications: The -TI5 Option uses Texas Instruments’ Direct Connect protocol for communicating to TI Series 505 PLC’s. All models in the TI500/505 Series have an RS232C serial port on the CPU module. The T-60 Series -TI5 Option uses this port for communication to the PLC.
READ WRITE Cmd Memory Type Range Data / Response • 1 STW Memory 1-15 1 word per register • 2 X Memory 1-1024 1 word per 16 bits • • 3 Y Memory 1-1024 1 word per 16 bits • • 4 V Memory 1-NN.
PL5 Interface Option Communications: The -PL5 Interface Option allows the T-60 Series to communicate to the Allen Bradley PLC-5 (Data Highway Plus™) through the 1785-KE or 1770-KF2 Series B Data Highway™ RS-232-C Interface Modules.
Configure the 1785 KE dip switches in the following manner: Configure the 1770 KF2 dip switche s in the following manner: SWITCH NUMBER 123456 SW1 Dn Dn Up Dn Dn SW2 Dn Dn SW3 Up Up Up SW4 Up Up Up SW.
Command Variations: The CALL PLCREAD and CALL PLCWRITE commands for the PLC-5 are significantly different from the other PLC’s described here. The following descriptions apply to the -PL5 Option onl.
Examples: 10 DIM regdat%(10) 20 CALL PLCREAD(1,4,16,,5,regdat%(4)) This command returns the contents of element 16 in regdat%(4), element 17 in regdat%(5), element 18 in regdat%(6), element 19 in regdat%(7), element 20 in regdat%(8), from file #4 in the PLC-5 with id #1.
sure you properly dimension the array prior to using it). If you are setting more than one, but less than 16 bits, you will be writing one word, and therefore can use a discrete variable name. If you are setting more than 16 bits, you will need to use an array.
-SL5 Interface Option Communications: The -SL5 Interface Option allows the T-60 Series to communicate to the Allen Bradley SLC-500 (DH-485Ô) through the 1747-KE DH-485Ô to RS-232-C Interface Module. The communications cable is EMERSON EMC’s standard Null Modem cable (N-MODEM-25-9 for the T-61 and N-MODEM-9-9 for the T-60 ).
Follow the setup guidelines for the 1747-KE module exactly. If possible, use your Allen-Bradley programming software to communicate to the SLC-500 once you perform all of the setup operations.
CALL PLCREAD Statement Syntax: CALL PLCREAD( id, type, file, address, [bit], count, variable/array ) Comments: This command is specific to the -SL5 Interface Option. id specifies the address of the PLC from which you wish to read data. This number is usually 1 when interfacing to one PLC.
you wish to store the data you are reading. If the value of count (see above) is 1, this will be a variable expression. If you are reading elements that are stored as words and count is greater than one, this will be an array (make sure you properly dimension the array prior to using it).
CALL PLCWRITE Statement Syntax: CALL PLCWRITE( id,type, file, address, [bit], count, variable/array ) Comments: This command is specific to the -SL5 Interface Option. id specifies the address of the PLC in which you wish to write data. This number is usually 1 when interfacing to one PLC.
you wish to store the data you are writing. If the value of count (see above) is 1, this could be a variable expression. If you are writing elements that are stored as words and count is greater than one, this will be an array (make sure you properly dimension the array prior to using it).
-OM1 Interface Option Communications: The -OM1 Option uses the Omron Host Link protocol for communicating to all suitably equipped Omron PLC’s. The Omron Host Link port is connected to the T-60 or T-61’s COM1 port via the supplied cable.
The -OM1 Option limits you to reading or writing a maximum of 32 words of data (512 bits) during one read or write operation. For example, you are restricted to accessing 32 registers in the DM area with one CALL PLCREAD or CALL PLCWRITE command. Addre ssing bits in the -OM1 Option is a little different than in the rest of the PLC interfaces.
The Omron status write must be performed in the following manner: CALL PLCWRITE(0,1,0,1,mode) mode: 0 - program 1 - debug 2 - monitor 3 - run The Omron PLC must be in the monitor mode to enable write commands to perform without errors.
-PL2 Interface Option (Preliminary) Communications: The -PL2 Option uses the programming port protocol for communicating to the Allen Bradley PLC-2. The T-60 Series can use the programming port on the PLC-2 CPU or the programming port on the 1771-KA2 Interface Module.
-IDEC FA-1JFA2-J Interface Option Communications: The -IDEC option uses the Idec protocol to communicate between the Series T-60 unit and the PLC. The unit is configured by using the -plcinit(x,y) co mmand. Connections : In order for the SeriesT-60 and the Idec unit to communicate, a specialized cable is sent with the Eason unit.
Available Commands: The commands listed in the table below list the commands available for the Idec FA-1J and the Idec FA-2J interface s. CALL PLCINIT Statement Purpose: This command is used to initialize communication with the IDEC FA-1J and FA-2J series PLC.
Syntax: CALL PLCINIT( id,cmd ) Comments: id specifies the address of the PLC that you wish to initialize. For the FA-1J and FA-2J series PLC, this number will always be 1.
CALL PLCREAD( 1, 12, 30, 1, t% ) This will capture the monitor value of a timer. CALL PLCWRITE Statement Purpose: This command is used to write value(s) to the IDEC’s register(s), memory location(s), or to force one or more output bits in a PLC.
-Mitsubishi FX PLC Interface ( -MFX ) Communications: The -MFX Option uses the Mitsubishi FX’s RS422 port to communicate with the T-60 Series products.
Available Commands : The commands listed in the table below list the commands available for the Mitsubishi FX series interfa ces. CALL PLCINIT Statement Purpose: This command is used to initialize communication with the FX. CALL PLCINIT must be issued prior to any other communication (reading or writing) to the specified PLC.
Syntax: CALL PLCINIT( id,cmd ) Comments: id specifies the address of the FX - always use 1. cmd specifies the communications mode: 1 - RS422, COM1 - most common and recommended.
than 16 bits of data, this variable MUST be a short integer (%) array variable. If you are reading registers or memory locations that are stored as words and the # of registers/bits is greater than one, this will be a short integer array (make sure you properly dimension the array prior to using it).
location at a time, this number will be the number of consecutive registers or locations you wish to write. If you are writing the status of more than one I/O bit, this number will be the number of consecutive bits you wish to write.
-SQD SQUARE D SY/MAX PLC Interface Communications: The SQD PLC option uses the SY/MAX RS422 port to communicate with the T-60 Series products. The connections are as fol lows: Figure 30 T-60 Interface.
CALL PLCINIT Statement Purpose: This command is used to initialize communication with the SY/MAX. CALL PLCINIT must be issued prior to any other communication (reading or writing) to the specified PLC. CALL PLCINIT auto detects the baud rate and parity.
Comments: id specifies the route. See CALL PLCINIT above. start address is the starting address of the register(s) you are interested in reading. [bit position] is an optional parameter which specifies the position within a 16 bit register to start reading from.
This command reads the data in register number 47 with and stores it in the variable regdat1%. 10 CALL PLCREAD(1,100,5,2,bits%) This command reads two bits from register 100 starting at bit position 5. The result is placed in the variable bits% with register 100, bit 5 in bit position 0, and register 100 bit 6 in bit position 6.
variable/array is the variable name or array name where you wish to store the data you are writing. If you are writing only one register or bit, you may use any variable type you wish. If you are writing multiple registers, this variable can either be a short integer (%) array variable or a constant (like 1234).
