Features
This command is used to write PMC Data of Machine Center Controller.
It is used when the data return type is bit.
Caution
Before driving the DRL, be sure to check the PMC Signal Map of the controller before driving.

Example
ErrCode, hMachineCenter = focas_connect("10.10.0.95", 8193, 10)
ErrCode = focas_pmc_write_bit(hMachineCenter, "R", 3000, 0, ON)
ErrCode = focas_disconnect(hMachineCenter)
