Monitoring functions
SIMOCODE pro supports two-phase monitoring of the analog signals of a
transducer (standard 0/4 - 20 mA output signal). The analog signals are fed
to the "0/4-20 mA" function block via the analog module.
Trip level, warning level
With 0/4-20 mA monitoring, you can parameterize two different response
levels (trip level/warning level) for the upper and lower limit.
Trip level
• 0/4-20> (upper limit)
• 0/4-20< (lower limit)
Warning level
• 0/4-20> (upper limit)
• 0/4-20< (lower limit)
Trip level and warning level activity
Here you can specify in which motor operating states the trip level/warning
level is to take effect:
• Always (on)
• Always, except TPF (on+)
• If motor is running, except TPF (run)
• If motor is running, except TPF,
with start-up override (run+)
Response when trip level 0/4-20 mA> (upper limit),
0/4-20 mA< (lower limit)
Here you can set how SIMOCODE pro should respond if the set trip level is
either undershot or overshot:

Trip level/warning level always takes effect,
regardless of whether the motor is running or
at a standstill
Trip level/warning level always takes effect,
regardless of whether the motor is running or
at a standstill, with the exception of "TPF", i.e.
motor feeder is in the test position.
Trip level/warning level only takes effect if the
motor is ON and not in the test position
The trip level/warning level only takes effect if
the motor is running and the start-up
procedure has been completed, and there is
no test position feedback (TPF)
