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