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.

The user can select a signal to be monitored by a peak value logger. The logger

value is sampled at 2 ms intervals.
