focas_pmc_read_double(handle, addr_type, start_num, read_count)
Features
This command is used to read PMC Data of Machine Center Controller.
It is used when the data return type is double (8Byte, 64-bit-floatring-point-type).
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, PMC_Data = focas_pmc_read_double(hMachineCenter,"D",10,3)
ErrCode = focas_disconnect(hMachineCenter)
