focas_pmc_read_bit(handle, addr_type, start_num, bit_offset)
Features
This command is used to read 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.
Parameter

Example
ErrCode, hMachineCenter = focas_connect(“10.10.0.95”, 8193, 10)
ErrCode, PMC_Data = focas_pmc_read_bit(hMachineCenter,"R", 3500, 0)
ErrCode = focas_disconnect(hMachineCenter)
