OPC90 Server
7.17 Multiplex CIU (MUXCIU)
The MUXCIU OPC90 block allows a configuration utility program, requiring
communication access to the Bailey system, to share the CIU device associated
with the OPC90 DEVICE block. This block does not support programs that need
to establish points in the CIU. Use this block to allow the Bailey CADEWS or
Composer software to communicate with the Bailey system via the OPC90
DEVICE block driver.
To accomplish this task, connect a RS232 serial cable between the COM port
must be made with a null modem cable. The MUXCIU
lock receives CIU commands sent by the configuration utility program via the
erial p chan e commands to the Bailey system through
