When powering up the module or when plugging it in, the TSX CFY module carries out auto-tests with the outputs in safety position (outputs at 0).
At the end of the auto-tests:
|
If the auto-tests
|
Then the module
|
|
have not detected any errors.
|
tests the configuration with the outputs in safety position. If the configuration is correct, the module switches to disabled mode (OFF).
|
|
have detected an error or the configuration is incorrect.
|
signals an error and retains the outputs in safety position.
|
All the operating modes of the configured channels are usable.
Switching the PLC from RUN to STOP mode
When switching the PLC from RUN mode to STOP mode or when there is a loss of communication between the processor and the module, the moving part decelerates and stops and the module switches to STOP mode (OFF).
NOTE: The IRSTSCANRUN bit (%S13) allows you to detect when the PLC switches to STOP mode. It is set to 1 during the first cycle after the PLC switches to RUN mode.
Changing configuration (reconfiguration)
-
The moving part decelerates and stops.
-
The channel becomes unconfigured.
-
The channel tests the new configuration with the outputs in safety position.
-
If the new configuration is correct, the channel switches to STOP mode (OFF).
-
If the configuration is incorrect, the module signals an error and retains the outputs in safety position.
When there is a power outage, the moving part stops.
At the time of a cold start or a warm restart, the configuration of the channels is automatically transmitted by the processor to the module The latter switches to STOP mode (OFF).
