13 Technical commissioning
The configuration of the MELSEC-WS safety controller has to be completed before
you begin with the technical commissioning.
13.1 Wiring and voltage supply
When connecting the MELSEC-WS safety controller, observe the technical
data in the Safety Controller User’s Manual!
Connect the individual field devices to the corresponding signal connections and
check for each safety input, test/signal output and safety output whether these
behave as required for the application. Diagnostics information from the
MELSEC-WS module’s LEDs support you in validating the individual field signals.
Check whether the external circuit, the realisation of the wiring, the choice of the
pick-ups and their location at the machine fulfill the required safety level.
Eliminate any faults (e.g. incorrect wiring or crossed signals) at each safety input,
test/signal output or safety output before you continue with the next step.
Switch on the voltage supply. As soon as the supply voltage is applied to the
connections A1 and A2 of the CPU modules or the WS0-XTIO modules, the
MELSEC-WS safety controller automatically carries out the following steps:
– internal self-test
– loading of the saved configuration
– testing of the loaded configuration for validity
The system does not start up if the steps described above could not be carried out
successfully. If there is an error, this is indicated correspondingly by the LEDs (see
the Safety Controller User’s Manual) and the safety controller only transfers Low
values.
13.2 Transferring the configuration
After you have configured the hardware and the logic in the MELSEC-WS safety
controller and have checked whether they are correct, transfer the configuration to
the safety controller via the Setting and Monitoring Tool.
