ABB CI856K01 S100 I/O Communication Interface

Configured for S100 I/O communication in AC 800M systems, the ABB CI856K01 (CI856 S100 I/O Communication Interface) provides the communication path between the AC 800M controller and S100 I/O racks. The CI856 connects to the CEX-Bus through the TP856 baseplate and requires no separate external power source.

CEX-Bus and S100 I/O Communication

The CI856 exchanges S100 I/O data with the AC 800M controller through the CEX-Bus interface. The TP856 baseplate provides the mechanical mounting interface and houses the ribbon connector used for connection to S100 I/O rack bus extender boards.

One CI856 can connect to up to five S100 I/O racks. Each rack can accommodate up to 20 I/O boards. Therefore, the supported architecture permits distributed S100 I/O expansion while retaining the controller-side CEX-Bus connection.

The module receives its operating power from the AC 800M processor unit through the CEX-Bus. Consequently, the CI856 does not require a separate external power supply.

The specified 36-pin Miniribbon connector provides the physical interface for the communication assembly. The TP856 baseplate also supports DIN-rail mounting for installation within the control cabinet.

Frequently Asked Questions (FAQ)

Q: How many S100 I/O racks can one CI856K01 support?
A: One CI856K01 can connect to up to five S100 I/O racks, with each rack supporting up to 20 I/O boards.

Q: Does the CI856K01 require an external power supply?
A: No. The CI856 receives power from the AC 800M processor unit through the CEX-Bus. Its typical 24 VDC consumption is 120 mA.

Q: What connector does the CI856K01 use for the CEX-Bus connection?
A: The supplied specification identifies a 36-pin Miniribbon connector. The connector is housed through the TP856 baseplate assembly.

Field Installation Guidelines

1. Mount the TP856 baseplate on a suitable DIN rail inside the control cabinet.
2. Install the CI856 communication interface on the TP856 baseplate according to the AC 800M hardware installation procedure.
3. Connect the baseplate to the CEX-Bus using the specified system connection arrangement.
4. Connect the TP856 ribbon interface to the S100 I/O rack bus extender boards.
5. Route communication and power-related wiring separately from high-current switching and high-noise circuits where practical.
6. Verify connector seating and mechanical retention before energizing the controller assembly.
7. Maintain cabinet grounding and shielding practices specified by the AC 800M and S100 I/O installation documentation.
8. Confirm that the installed rack count and I/O board count remain within the CI856 architecture limits.
9. Check the cabinet operating temperature against the specified 0 to +55 deg C range.
10. Inspect the installation for correct IP20 enclosure protection and adequate environmental control.
