Setting up and Sensing Alarms

Use PME to assign bits in the %Q output table to control whether GLM alarms for a target device will be
enabled or disabled. These are shown as the Port Alarm Outputs in Figure 36.
The Alarm Enabled bits are contiguous and must be assigned a starting location in %Q on a byte boundary.
Figure 36 uses %Q00001 for simplicity, but this starting location can be any multiple of 8, plus 1. For instance,
%Q00401 would be another suitable starting location.
To enable or disable an alarm, refer to Section 4.3.3 for Slot 3: Port Alarm & Port Settings & Status.

Figure 36: GLM Switch Parameters Set in PME

Use PME to assign bits in the %I input table to determine where the PLC may sense the corresponding alarm
conditions associated with the target device. These are shown as the Port Alarm Inputs in Figure 36.
The Port Alarm Input bits are contiguous and must be assigned a starting location in %I on a byte boundary.
The table above uses %I00129 for simplicity, but this starting location can be any multiple of 8, plus 1. For
instance, %I00401 would be another suitable starting location.
When an alarm is present, the corresponding Port Alarm Input bit will register as "1'; when no alarm is present,
it will register as "0". Refer to Section 4.3.3, Slot 3: Port Alarm & Port Settings & Status for details.
The Port Admin Input and Port Admin Output are used by the console function to read the Alarm Input senses
and enable/disable the alarms as shown in Figure 37. The starting addresses may be assigned to any
available non-conflicting %I and %Q starting references. The corresponding starting location can be any
multiple of 8, plus 1.
