Network connection between Momentum PLC and touch screen, monitoring hostRemote program maintenance and fault diagnosis on field controllersData sharing among multiple Momentum PLC stationsTransformation upgrade of old Momentum control system with Ethernet function

Cut off all power supply of the whole Momentum system before operation.Wear anti-static protective equipment to avoid static damage to circuit board.Align the adapter with expansion slot of CPU module, insert firmly and lock fixing screws.Connect standard network cable to RJ45 port of the adapter and switch or terminal device.Restore system power supply, observe LINK and ACT indicator working state.Complete IP address setting and network parameter configuration via supporting programming software.Download program and verify normal network communication function.

Matching CPU: All 171CCC and 171CCS series Momentum processorsMatching I/O base: Full range 170XTS series discrete and analog I/O basesApplicable software: Concept, ProWORX 32, Modsoft programming software

Installation and maintenance work must be operated by qualified electrical staff.Always disconnect power before disassembling, assembling or wiring.Keep module away from liquid, corrosive gas and conductive dust.Do not disassemble internal structure, no user maintainable parts inside.

Regularly check module surface, connector and fixing condition every quarter.Clean dust with dry soft cloth strictly, do not use chemical solvent.No LINK light: Check network cable integrity, port connection and power supply status.ACT light no flicker: Confirm IP address setting, network segment matching and station communication configuration.Intermittent communication failure: Inspect wiring fixation and eliminate nearby strong electromagnetic interference source.

This model is discontinued. Replace with 171CCC96030 or 171CCC98030 integrated Ethernet processor module for system upgrading.
