Assignment Of Keys And Leds To The Plc Inputs And Outputs - HEIDENHAIN TNC 415 Technical Manual

10.3.1 Assignment of keys and LEDs to the PLC inputs and outputs

The 12 keys of handwheel HR 332 are assigned to different PLC inputs and the 12 LEDs to different
outputs depending on the input value of machine parameter MP7645.0.
Pressing a key sets the corresponding PLC input. The matching LED lights up when the PLC output
is set.
When MP7645.0 = 0, the X, Y, Z, IV and V keys and their LEDs are assigned to the NC. The other
keys are assigned to PLC inputs I164 to I170. The LEDs are assigned to the PLC outputs O100 to
O106.

When MP7645.0 = 1, all 12 keys are assigned to PLC inputs I160 to I171 and all LEDs to PLC
outputs O96 to O107.

MP7645 Initializing parameters for handwheel
MP7645.0 has the following meaning when an HR 332 is connected:
MP7645.0 Assignment of HR 332 handwheel keypad
Entry: 0 to 255
0 = all keys and LEDs are freely addressable with the PLC except for axis
selection keys and their LEDs
1 = all 12 keys and LEDs are freely addressable with the PLC.
MP7645.1 to MP7645.7 are not assigned
