1 Overview Introduction You use the DP/ASi link to interface the Actuator Sensor Interface to the PROFIBUS-DP. Devices and mod- The DP/ASi link operates as a DP slave and requires a DP master – for exam- ules ple, an IM 308-C.

Overview 1.1 Using the DP/ASi Link The DP/ASi link connects the Actuator Sensor Interface (referred to in the Definition following as ASi) to the PROFIBUS-DP. PROFIBUS-DP conforms to the PROFIBUS-DP standard EN 50170 Vol- ume 2, PROFIBUS; the term DP means ”distributed I/O”. You will find an explanation of how the ASi works in Chapter 2.

Overview 1.2 What is the DP/ASi Link? The DP/ASi link connects the actuator sensor interface (ASi) to the PROFI- Definition BUS-DP field bus. In doing so, the protocols of the bus systems are conver- ted. Overview The DP/ASi link belongs to the Distributed I/O. The DP/ASi link is a DP slave. In addition, other components belong to the DP/ASi link. Not all components are necessarily required for operation: Components T connector PS SV Power supply connector cntr PG Programmer connector 2-core Bus

2 ASi Basics Introduction 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. Definition The Actuator Sensor Interface is a wiring system to which a master and up to 31 slaves can be connected. The ASi master (the DP/ASi link) periodically transfers input and output data from and to all the ASi slaves within a period not exceeding 5 ms. The slaves may be configured as modules or intelligent actuators an
