Module 9180 Simulation of NC keys

With this module you can simulate the activation of 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 W1022
Error recognition:
Marker Value Meaning
M4203 0 NC key was simulated
1 Error code in W1022
W1022 1 Transferred parameter > maximum value
2 Transferred parameter invalid
22 Keystroke queue overflow

Module 9181 Disable individual NC keys

With this module you can disable individual NC keys.
If you press a disabled key, marker M4577 is set.
Call:
PS B/W/D/K <Key code>
CM 9181
PL B/W/D <Error status>
0: NC key disabled
-1: For error see W1022
Error recognition:
Marker Value Meaning
M4203 0 NC key was disabled
1 Error code in W1022
W1022 1 Transferred parameter > maximum value
2 Transferred parameter invalid
Keystroke Simulation 6 – 339
