MACHINE_TENDING_FOCAS_PMC

PMC (Programmable Machine Control) header + payload for FOCAS operations. The header specifies target address/type/range; the payload holds typed data buffers.

BYTE#	Field Name	Data Type	Value	Remarks
0	_ErrorCode	short		0 on success; negative/positive for errors
2	_hHandle	unsigned short		Active FOCAS session handle
4	_iDataType	short		PMC data type selector (vendor-defined)
6	_szAddressType	char[2]	e.g. “G”, “D”	PMC address type as a one-letter string, for example “G” or “D”.
8	_iStartAddressNum	unsigned short		Start address number (word/bit base)
10	_iCount	unsigned short		Number of PMC items to read/write
12	_iBitOffset	unsigned char	0-7	Bit offset for bit-level access
13	_tData	MACHINE_TENDING_FOCAS_PMC_DATA		Typed PMC payload buffers

Size note: The total size is platform-dependent (sizeof(long)).
