Sinumerik Alarm 4270 Machine data %1 assigns not activated NCK input/output byte %2
%1 = String: MD identifier
%2 = Index
The specified machine data assigns a digital input/output byte or an analog input/output signal the processing of which has not been activated to an NC function.
– Alarm display.
– Interface signals are set.
– NC not ready.
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
Please inform the authorized personnel/service department. Correct machine data.Activate required inputs/outputs via MDs:
Activation of fast inputs/outputs does not require the corresponding hardware configuration to be available at the control.All functions using fast inputs/outputs can also be made use of by the PLC specification/modification defined in the VDI interface, if the response time requirements are reduced accordingly.
Activated inputs/outputs increase the computation time requirement of the interpolation cycle because the PLC manipulation signals are handled cyclically.
Note: Deactivate any inputs/outputs not in use.
Switch control OFF – ON.
