Installing the S100 I/O Interface, CI856/TP856
The CI856 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 CI856/TP856:
1. Mount the unit on 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. Connect the S100 I/O cable, TK575/TK580, to the contact on the baseplate. A
bus extender, DSBC174/DSBC176/DSBC173A, must be used.
S100 I/O Connection and Installation
Connect the S100 I/O rack cable TK575/TK580 to the “I/O-labeled” 36-pin
centerline miniature ribbon connector located on TP856.
