Compact utility outstation / EN/IEC60870-5-101 slave RTU870

The three-octet binary time tag is added automatically by the firmwarefor each information object address.

The three-octet binary time tag is added automatically by the firmwarefor each information object address. A number of BM registers are used by the B-CON application program, in conjunction with some configuration registers, to control the IEC60870-5-101 slave driver. The BM registers are defined as follows:
