Alarm Handling

In the PS564 library are two categories of alarm:

• Fault: leads to stop of the process
• Warning: process continues with warning indication

Fault is triggered if something serious happens, which must stop the process, otherwise the machine as well as the production material can be damaged.

In practice, the user can use the individual alarm bit to do some control or give some indication out of PLC, e.g. switching off a contactor or switch on an alarm light.

• Temperature Limits
