Parameters: %1 = PLCIO error code
Definitions: This alarm indicates that errors occured when writing on the PLCIO with the FastPlcCom
functionality.
Reactions: - Alarm display.
Remedy: Check machine data MD 10396/103947 or check the PLC hardware configuration.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
4260
Machine data %1 illegal
Parameters: %1 = String: MD identifier
Definitions: Selected cam pair not activated by MD $MN_SW_ASSIGN_TAB or several cam pairs
selected.
Reactions: - Mode group not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Activate the cam pair or select only one cam pair.
Program Con- Switch control OFF - ON.
tinuation:
4270
Machine data %1 assigns not activated NCK input/output byte %2
Parameters: %1 = String: MD identifier
%2 = Index
Definitions: 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.
Reactions: - NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Correct machine data. Acti-
vate required inputs/outputs via MDs:
• $MN_FASTIO_DIG_NUM_INPUTS
• $MN_FASTIO_DIG_NUM_OUTPUTS
• $MN_FASTIO_ANA_NUM_INPUTS
• $MN_FASTIO_ANA_NUM_OUTPUTS
Activation of fast inputs/outputs does not require the corresponding hardware configura-
tion 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.
Program Con- Switch control OFF - ON.
tinuation:
4275
Machine data %1 and %2 both assign the same NCK output byte no. %3 several
times
Parameters: %1 = String: MD identifier
