6.32 NC_COMMAND_SET_VIRTUAL_WHEEL Virtual Handwheel Feature


1.

The PLC can use NC_COMMAND_SET_VIRTUAL_WHEEL to specify the virtual handwheel counter.
  • .x to set the virtual handwheel to use a set of plc short data as the virtual handwheel count value.
  • .x>=1 and .X<1024 indicate the use of short data for the corresponding group number. Otherwise, this function is disabled and the original normal handwheel is restored. For example: x=70, which means using PlcData[70] as the counter value of the virtual handwheel.

2.

The counter value is 16bit, 2's complement value.

3.

plc changes this value to make a virtual handwheel. Note that this value must be changed incrementally. Do not change quickly.

4.

sts.state3.bVirtualWheel will be 1 if the virtual handwheel is enabled, otherwise it will be 0.
