Cut off system power before any installation work.Apply electrostatic protection to avoid component static damage.Align the adapter with CPU expansion slot, insert tightly and fasten mounting screws.Connect qualified Ethernet cable between RJ45 port and network switch or terminal device.Restore power supply and check LINK and ACT LED working status.Configure IP address, subnet mask and relevant network parameters via programming software.Test program downloading and cross-device data communication.

Applicable Processors: All 171CCC and 171CCS series Momentum CPUsApplicable I/O Bases: All 170XTS discrete and analog I/O basesApplicable Software: Concept, ProWORX 32, Modsoft

Only qualified professional personnel can perform installation and maintenance.Disconnect power completely before disassembly and wiring operation.Keep module away from liquid, corrosive gas and conductive dust.Do not open module casing, no user serviceable internal parts.

Conduct visual inspection quarterly for loose fixing and connector damage.Clean surface dust only with dry soft cloth, avoid chemical solvents.No LINK light: Check power supply, network cable and port connection.No ACT data flash: Verify IP configuration, network segment and communication settings.Unstable communication: Reinforce wiring and isolate strong electromagnetic interference sources.

This model is obsolete. Recommended replacement modules are 171CCC96030 and 171CCC98030 with built-in Ethernet port for integrated network control.
