Power Supply of the ET 200iSP
Power supply PS
Connect the voltage supply of ET 200iSP to terminal module TM-PS-A/ TM-PS-A UC of the
power supply. The power supply provides the required output voltages for the ET 200iSP. The
output voltages are electrically isolated from the supply voltage.
● Power supply PS 24 VDC: 24 VDC
● Power supply PS 120/230 VAC: 85 - 264 VAC

Direct data exchange
Prerequisites
The ET 200iSP can be used as publisher for direct data exchange (cross communication).
This requires no configuration.
The DP master you are using must, of course, also support direct data exchange. You will find
information on this in the description of the DP master.
Principle of operation
Direct data exchange is characterized by PROFIBUS DP nodes which "listen" on the bus and
know which data a DP slave returns to its DP master. With this mechanism, the "listener"
(recipient) can access changes to the input data of remote DP slaves directly.
During configuration in STEP 7, you use the peripheral input addresses to specify the address
area of the recipient in which the required data of the publisher will be read.
