Supervisory Processor (PLCĆ2/30, PLCĆ3, PLCĆ5, or PLCĆ5/250)
Follow these guidelines when programming block-transfer instructions in
the supervisory processor.
Set the length to 0.
Set the continuous bit for continuous operation (PLC-5 and -5/250
processors only).
Use the remote I/O rack number for which you configure the adapter-
mode processor.
Use 0 for the group and module numbers.
Condition the use of BTR data with a “data valid” bit.
All address comments for contacts shown in the following examples
represent the set (1) state of the bit in the PLC-5 processor.
