Operating the Module without Alarm Processing
You can also use the module as a straightforward digital input/output module, in which case, the
mode selector on the back of the module is set to the "ALARM OFF" position. When operating
without alarm processing, you can use the module in all central controllers (CR 700-0/1/2/3) and in
all expansion units (ER 701-0/1/2/3). Further parameterizing of the module is not required. You
can address the module like any normal input/output module without restriction.
