Field in ModBus data structure

Hi,

I was going through the example in B&R Online Help .

I was wondering what does the structure member “mfc” in CmdTable_typ refer to? Is it part of an information piece in the modbus protocol message?

Thanks and Regards,
Kenneth

mfc stands for modbus function code, which is defined in the modbus protocol.
