1)
If you use the module in ER-1/ER-2, you must set this parameter to “No” because the interrupt lines are
not available in ER-1/ER-2.
2)
Only in the CC (central controller) is it possible to start up the analog modules with the default settings.
A Point to Note About Channels for Hardware Interrupts with the End of Scan
Cycle Trigger
You can parameterize hardware interrupts for the end of scan cycle for one of the
16 channels because the module can only trigger these interrupts on one channel.
