The Shift RBE COMMREQ requests that the RBE be shifted from one Client connection to other Client

connection associated with specified Port number. This COMMREQ can be triggered via positive edge

trigger. On event of failure of the existing Client connection (which has RBE), the RBE can be shifted in

runtime to other Client connection using this COMMREQ. The Status bit "Client connection XX" as

defined in the Status Area in Appendix A.

The COMMREQ Status Word (CRS) indicates the success or failure of this COMMREQ. If the COMMREQ

requests an invalid Client Connection Port number, then the COMMREQ fails and the CRS is set to a non-

zero value to identify the failure.

See the section "The Communications Request" in the document GFK-2224 for general description of

CCOMMREQ configuration.

Command 1242 Example
