Pin
A1
24 V voltage supply for all the modules, with the exception of the outputs
(Q1...Q4)
A2
GND of the voltage supply
Meaning
Switch on the supply voltage and check
it at the terminals A1 and A2.
Please wait ...
Start the application in the Setting and
Monitoring Tool.
Check the module type and version of
the CPU module and safety I/O
modules whose MS LED flashes
Red/green.
If appropriate, adapt the configuration
using the Setting and Monitoring Tool.
For detailed information refer to the
Setting and Monitoring Tool,
Diagnostics view.
Switch the supply voltage off and on
again. If the error is not eliminated after
multiple repetition, replace this module.
For detailed diagnostics information
refer to the Setting and Monitoring Tool.
Switch the supply voltage off and on
again.
If the error is not eliminated after
multiple repetition, replace the module
which displays
not the case, use the diagnostic
functions of the Setting and Monitoring
Tool to narrow down the respective
module.
Meaning
Supply voltage may not be interrupted
until the storage process has been
completed.
Verify configuration with the Setting and
Monitoring Tool.
