Fault and warning messages, data logging

See chapter Fault tracing


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
status is activated, and a warning or fault generated. The contents of the message
can be edited on the control panel by selecting Menu - Settings - Edit texts.
The supervised signal is low-pass filtered. The supervision operates on a 2 ms time
level. The configuration parameters are scanned for changes on a 10 ms time level.



Maintenance timers and counters

The program has six different maintenance timers or counters that can be configured
to generate a warning when a pre-defined limit is reached. The contents of the
message can be edited on the control panel by selecting Menu - Settings - Edit
texts.
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.
