    NOTE: active at a time. The 345 can be used as an IEC 60870-5-104 slave device connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the 345 maintains two sets of IEC 60870-5-104 data change buffers, no more than two masters should actively communicate with the 345 at one time.

    For the 345 implementation of Modbus, this function code can be used to read any setpoints (“holding registers”). Holding registers are 16 bit (two byte) values transmitted high order byte first. Thus all 345 Setpoints are sent as two bytes. The maximum number of registers that can be read in one transmission is 125.

    MODBUS FUNCTIONS CHAPTER 1: COMMUNICATIONS GUIDE For the 345 implementation of Modbus, this function code can be used to read any actual values (“input registers”). Input registers are 16 bit (two byte) values transmitted high order byte first. Thus all 345 Actual Values are sent as two bytes. The maximum number of registers that can be read in one transmission is 125.

    Function Code 08H Modbus Implementation: Loopback Test 345 Implementation: Loopback Test This function is used to test the integrity of the communication link. The 345 will echo the request. For example, consider a loopback test from slave 17: Table 39: MASTER/SLAVE PACKET FORMAT FOR FUNCTION CODE 08H...

    Error Responses When a 345 detects an error other than a CRC error, a response will be sent to the master. The MSBit of the FUNCTION CODE byte will be set to 1 (i.e. the function code sent from the slave will be equal to the function code sent from the master plus 128).

    USING THE MODBUS USER MAP Using the MODBUS User Map 345 relay units incorporate a powerful feature called Modbus User Map, that allows the user to read 125 non-consecutive data records. A master computer will often have to interrogate continuously several connected slave relays.
