Program Con-
tinuation:
Switch control OFF - ON.
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 pro-
cessing of which has not been activated to an NC function.
Reaction: 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.
Active required inputs/outputs via MD:
• MD 10350 FASTIO_DIG_NUM_INPUTS
• MD 10360 FASTIO_DIG_NUM_OUTPUTS
• MD 10300 FASTIO_ANA_NUM_INPUTS
• MD 10310 FASTIO_ANA_NUM_OUTPUTS
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.
Program Con-
tinuation:
Switch control OFF - ON.
4275 Machine data %1 and %2 both assign the same NCK output byte no. %3
several times
Parameters: %1 = string: MD identifier
%2 = string: MD identifier
%3 = No. of output
Definitions: The specified machine data assign two NC functions to the same digital/analog output.
Reaction: 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.
Program Con-
tinuation:
Switch control OFF - ON.
4280 Assignment of NCK input/output byte via MD %1[%2] does not match
hardware configuration
Parameters: %1 = String: MD identifier
%2 = Index: MD array
Definitions: When booting, the required input/output module was not found at the slot specified in the MD.
Reaction: 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. Check hardware and correct the MD if
necessary. Note: Monitoring of the hardware configuration is performed independently of the number
of activated inputs/outputs (MD 10300 - 10360 FASTIO_ANA(DIG)_NUM_INPUTS(OUTPUTS))
Program Con-
tinuation:
Switch control OFF - ON.
