IQS-233 Operating Manual
2.3.3.6.4 I/O Tab
Various events can be assigned in the I/O tab (see Figure 2-40 ) to correspond to
the relays and inputs of an external Programmable Logic Controller (PLC).
IQM-233 and SQM-242 cards do not provide digital I/O. The PLC can provide the
relays and inputs needed for automatic control of source and sensor shutters,
rotation of source indexer pockets, etc.
NOTE: Programmable Logic Controllers use relay and input addressing. Relay
addresses correspond to relays 1 to 16 in the Relay Events pane. Input
addresses correspond to inputs 1 to 12 in the Input Events pane. (Refer to
the PLC operating manual for addressing.)
