24N978 – FO Converter

Used with FO Converter (Kit 24N978) to enable Modbus TCP communication. Can be connected to GRACO PN 15V337 AWI module. Includes terminal connection specifications for FO Converter terminals A(15), C(16), E(17). Items marked with dashes are not sold separately. Kit for Modbus TCP/AWI Communication. Used with fiber optic cable for crossover connection from FO Converter to DCM or ADCM. For Modbus TCP with PLC: connect customer-supplied ethernet cable (CAT 5, RJ45) from ethernet port to Modbus Gateway then to available ethernet port on PLC. For AWI Communication with PC: use provided ethernet cable to connect Modbus Gateway ethernet port to ethernet switch, then use second user-supplied ethernet cable to connect ethernet switch to PC. Kit 24N977 is used in conjunction with Kit 24N978 for Modbus TCP/AWI Communication. The Modbus Gateway connects to ethernet switch via CAT 5/RJ45 cable and can be installed in multiple configurations including AWI modules and DIN rail mounting.
