4 Bailey Communication Overview
Bailey utilizes a communication technique for data exchange called exception
reporting. Exception reporting means the data is sent when it has changed
significantly or a maximum time has expired since the last time it was sent. All
exception reported data is made available to the rest of the system via a set of
exception report related function blocks which are matched by an equivalent
OPC90 Server block. Bailey has a series of RS232 serial based devices
generically called Computer Interface Units that are utilized to receive this
exception report data. Note that communication with the INICI03 interface can
be either RS232 or SCSI. RoviSys is extremely knowledgeable on the use of the
various Bailey interfaces and has implemented a single driver that can utilize the
following types of interfaces:

When using these interfaces, the ABB Bailey semAPI software environment is
not required. The INICI12, INIC13, and INICI03 do not support dual channel
serial communication. When using serial communication to the INICI12,
INICI13 and INICI03, make sure the cable is attached to the port labeled
“terminal” on the ABB Bailey termination unit or termination module. See the
sections “Add” and “Device Definition Block” for information regarding SCSI
communication with the INICI03.
