1-1 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b Overview Y ou use the DP/ASi link to interface the Actuator Sensor Interface to the PROFIBUS-DP . The DP/ASi link operates as a DP slave and requires a DP master – for exam- ple, an IM 308-C.
1-2 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 1.1 Using the DP/ASi Link The DP/ASi link connects the Actuator Sensor Interface (referred to in the following as ASi) to the PROFIBUS-DP . PROFIBUS-DP conforms to the PROFIBUS-DP standard EN 50170 V ol- ume 2, PROFIBUS; the term DP means ”distributed I/O”.
1-3 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 1.2 What is the DP/ASi Link? The DP/ASi link connects the actuator sensor interface (ASi) to the PROFI- BUS-DP field bus. In doing so, the protocols of the bus systems are conver- ted. The DP/ASi link belongs to the Distributed I/O.
1-4 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b Connections – PROFIBUS-DP – ASi cable – 24 V DC power supply Optical isolation between PROFIBUS-DP and ASi Direct ET 200.

1-6 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b Overview.
2-1 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b ASi Basics If you wish to acquire a general idea of ASi, this is the right chapter for you. If you are already familiar with ASi, you can skip this chapter . The Actuator Sensor Interface is a wiring system to which a master and up to 31 slaves can be connected.
2-2 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 2.1 Structure of ASi Y ou can install the ASi as branched with a single 2-wire cable. Y ou connect the DP/ASi link, the different ASi slaves and the ASi power supply unit to any point on the ASi cable.
2-3 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 2.2 Elements of ASi The DP/ASi link is the ASi master . It controls communication in the ASi. The DP/ASi link periodically exchanges data with the ASi slaves. ASi slaves are the input and output channels of the ASi.
2-4 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b Y ou use the ASi distribution unit when you branch the ASi cable without using an ASi slave reroute the ASi cable to a normal 2-wire cable. The ASi distribution unit is designed as a module and is not assigned an ASi address.
2-5 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 2.3 Example Configuration of a Module Every module consists of an upper part and a lower part. As an example, you can see an illustration in Fig. 2-2 of an upper part with two inputs and two outputs and a lower part for the ASi cable without an in- terface for an external power supply .
2-6 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 2.4 Connecting Elements Y ou connect the elements of the ASi by attaching the modules to the ASi cable. Y ou do not have to operate the ASi cable for this. The ASi cable is connected to the DP/ASi link by means of a connector .
2-7 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 2.5 Interruption or Short-Circuit of the ASi cable If the ASi cable is short-circuited due to pinching or fraying of the insulation, data exchange no longer takes place on the ASi cable.

3-3 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 3.2 Configuration without T Connector and with Power Supply Connec- tor In a configuration with a looped-through field bus and a power supply , the DP/ASi link is connected directly to the PROFIBUS-DP .
3-4 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 3.3 Configuration with T Connector and with Power Supply Connector In a configuration with a power supply connector and a T connector , the DP/ ASi link is connected by means of a T connector to the PROFIBUS-DP .
3-5 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b W ith the DP/ASi link, spur lines are not authorized except for the program- mer or the ET 200 Handheld. This means that the 12-pin plug of the T con- nector is always screwed directly to the bus connection of a module.
3-6 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 3.4 Configuration with Several Power Supply Connectors In configurations with a power supply connector (refer to sections 3.
3-7 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 3.5 Configuration without Power Supply Connector In a configuration with a separate power supply , every slave station is sup- plied with power separately . This power supply must not be fed on the bus cable.
3-8 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b W ith the DP/ASi link, spur lines are not authorized except for the program- mer or the ET 200 Handheld. This means that the 12-pin plug of the T con- nector is always screwed directly to the bus connection of a module.
3-9 Distributed I/O System DP/ASi Link EW A 4NEB 710 6055-02b 3.6 Configuration with Programmer Connector If you wish to operate the programmer on the PROFIBUS-DP in an IP 66/IP 67 environment, you require a programmer connector .
