Monitoring
10.3.1 Monitoring with the PLC in operation and with the PLC stopped
It must be borne in mind that the CNC initializes all physical outputs and the PLC resources on power-
up, after the key sequence [SHIFT]+[RESET] and after detecting a watchdog error at the PLC.
The initialization process sets all resources to "0" except those active low. They will be set to "1".
During the monitoring of the PLC program and the various PLC resources, the CNC will always show
the real values of the resources.
If the PLC is on, note that a program cycle is processed in the following way:
• The PLC updates the real input values after reading the physical inputs (from the electrical
cabinet).
• It updates the values of resources M5000 thru M5957 and R500 thru R559 with the values of
the CNC logic outputs (internal variables).
• It runs the program cycle.
• It updates the CNC logic inputs (internal variables) with the real values of resources M5000 thru
M5957 and R500 thru R559.
• It assigns to the physical outputs (electrical cabinet) the real values of the corresponding "O"
resources.
• It copies the real values of resources I, O, M into their own images.
