Module 9180 Keystroke simulation
The module simulates NC keys and soft keys. You transfer the code of the
desired key.
If you transfer the code value zero, the number of occupied elements in the
keystroke queue is returned. In this case there is no keystroke simulation.
Call:
PS B/W/D/K <Key code>
CM 9180
PL B/W/D <Number of occupied elements / error status>
0: Key code was transferred, key queue is empty
1 to 16 : Key code was not yet simulated, max. 16 entries in
the keystroke queue are possible
–1: For error see NN_GenApiModuleErrorCode
Error recognition:
Marker Value
NN_GenApiModule 0
Error
1
NN_GenApiModule 1
ErrorCode
2
22
Module 9181 Disable NC key by PLC
The module disables individual NC keys.
Call:
PS B/W/D/K <Key code>
CM 9181
PL B/W/D <Error status>
0: NC key disabled
–1: For error see NN_GenApiModuleErrorCode
Error recognition:
Marker Value
NN_GenApiModule 0
Error
1
NN_GenApiModule 1
ErrorCode
2
Meaning
NC key was simulated
Error code in NN_GenApiModuleErrorCode
Transferred parameter > maximum value
Transferred parameter invalid
Keystroke queue overflow
Meaning
NC key was disabled
Error code in NN_GenApiModuleErrorCode
Transferred parameter > maximum value
Transferred parameter invalid
