Data exchange with the Master Unit via 8 inputs and 8 outputs.
Simple communications functions using the CPM2C-CIF21 Simple Communications Unit
Up to 32 communications components can be connected, including communications com-
ponents supporting the CompoWay/F protocol and temperature controllers and Digital
Panel Meters supporting the SYSWAY protocol.
Either RS-422 or RS-485 connections.
Variations/Details
Scheduled interrupts
One-shot interrupt
No interrupt
Count-check interrupt
(An interrupt can be generated when the
count equals the set value or the count
lies within a preset range.)
No interrupt
Count-up interrupt
