● Signal source, forced checking procedure (test stop) (p10007)
Select an input terminal to start forced dormant error detection (test stop):
– Forced dormant error detection (test stop) is started with a 0/1 signal of the input
– The TM54F must be in the "Ready" state.
– The F-DI of the TM54F must not be used as a signal source.
● Test cycle, dynamization F-DO (p10003)
Fail-safe inputs and outputs must be tested for fail-safety at defined time intervals (forced
dormant error detection or test stop). The TM54F module contains a function block that
runs this forced dormant error detection (test stop) when selected via a BICO source (e.g.
switching the sensor current supply L1+ and L2). Each selection triggers a timer in order
to monitor the test cycle. A message is set on expiration of the monitored time. This
message is also set following each switch on/off.
● Perform test stop automatically during startup
If you activate this option, forced dormant error detection (test stop) can be performed
automatically every time the power supply is switched on (POWER ON) (p9507.6 = 1).
