Signal supervision
Three signals can be selected to be supervised by this function. Whenever a
supervised signal exceeds or falls below predefined limits, a bit in

.
The timer/counter can be set to monitor any parameter. This feature is especially
useful as a service reminder.
There are three types of counters:
• On-time timers. Measures the time a binary source (for example, a bit in a status
word) is on.
• Signal edge counters. The counter is incremented whenever the monitored binary
source changes state.
• Value counters. The counter measures, by integration, the monitored parameter.
A warning is given when the calculated area below the signal peak exceeds a
user-defined limit.
