Installing the PROFIBUS DP-V1 Interface, CI854/TP854
The CI854 is powered from the processor unit via the CEX-bus and requires
therefore no additional external power source.
Use the following procedure to install the CI854/TP854:
1. Mount the unit onto the DIN-rail, see Mounting AC 800M Units onto DIN-Rail
on page 49 and Installing the PM8xx/TP830 Processor Unit in Single
Configuration on page 56.
2. Install a connector on the PROFIBUS DP-V1 cable. Connect the cable screen
to the ground terminal within the connector to ground the screen via CI854. A
connector with a switchable built-in bus termination is recommended.
3. Connect the PROFIBUS DP-V1 cable to one of the contacts PROFIBUS A or
PROFIBUS B on the baseplate. For support of Line Redundancy connect a
second PROFIBUS DP-V1 cable to the other contact.
4. If the CI854 is at the end of the PROFIBUS DP-V1 cable, switch the bus
termination ON. Otherwise leave the bus termination switched OFF.
PROFIBUS DP-V1 Connection
The PROFIBUS DP-V1 cable is connected via the 9-pin female D-type connector
located on TP854.
