Modbus Implementation Tank Gauge Transmitter 48 Installation and Operations Manual Table 9-1: Modbus Functions Note! Exception: Because the A TT does not dist inguish between inputs and outputs, func- tion codes 01 and 02 as they apply to bits, and function codes 03 and 04 as they apply to numeric valu es re fe r to th e sam e data re giste rs.
49 4000 Modbus Implementation 9.4 Functions and Data F or mats The Modbus data in the ATT is arranged in in teger registers, floati ng point r egisters, and status bits. The assignments for these registers are found at th e end of this appendix. Function codes 03, 04, 06, and 16 are us ed with integer registe rs.
Modbus Implementation Tank Gauge Transmitter 50 Installation and Operations Manual Note! In all of the foll owing communication examples, the error check valu e is dependent upon the mode of transmission. 9.5.1 Integ er Dat a The integer data is a whole number be tween 0 and the maximum Modbus integer (inclusive).
51 4000 Modbus Implementation 9.5.2 Integer Dat a • Hexade cimal representation • 4124Decimal equivalent: 16,676 The data returned for data address 56 is 16, 676 (4124 Hex). This value must be scaled using the following formula to give it meaning.
Modbus Implementation Tank Gauge Transmitter 52 Installation and Operations Manual 9.5.4 Coded Da t a Coded da ta represents a tabl e look-up value. Data written to these registers must be a valid table entry. Inval id data may cause a Configuration Error to occur.
53 4000 Modbus Implementation 9.6 Floating-P oint Re gisters Although not part of the Modbus protocol sp ecification, floating point numbers have been implemented usi ng the IEEE 754 standard.
Modbus Implementation Tank Gauge Transmitter 54 Installation and Operations Manual 9.6.4 The One 32-bit Reg ister Format Function code 65 (41 Hex) is used to read floating-point register s in this format. An example of a floating-point re gister read is shown below with the a temperature of 100.
55 4000 Modbus Implementation 9.7 Status Bits In the ATT implementation, status bits contain alarms, commands, and s tatus information. The state of a Modbus status bit is defined as eithe r ON (true) or OFF (false). The ON state is repres ented by a "1".
Modbus Implementation Tank Gauge Transmitter 56 Installation and Operations Manual 9.9 Data Out of Range When integer data calculated by the ATT is outside the minimum or maximum scale points or is otherwise out of range, the va lue returned is that of the maximum Modbus integer + 1.
57 4000 Modbus Implementation Termination resistors of 120 Ohms are shown at each end of the communic ation bus to minimize reflections on the line. Terminatio n resistors may not be necessar y at baud rates of 9600 bits per second or slower. Pull-up and pull-down resistors are also s hown at the Modbus master end of the cable.
