Z1: NC/PLC interface signals
19.1 Various interface signals and functions (A2)
Basic Functions
1614 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
Signal state 0 The control is not ready. The relay contact "NC Ready" is open.
The following faults will cause NC Ready to be canceled:
• Undervoltage and overvoltage monitoring function has responded
• Individual components are not ready (NCK CPU Ready)
• NC CPU watchdog
If the signal "NC Ready" goes to 0 the following measures are introduced by the control if they are
still possible:
• The controller enable signals are withdrawn (this stops the drives)
• The following measures are introduced by the PLC basic program:
– Status signals from NCK to PLC (user interface) are deleted (cleared)
– Change signals for help functions are deleted
– Cyclic processing of the PLC to NCK user interface is terminated
For further information see References!
The control is not ready again until after POWER ON.
