System compatibility

Compatibility description: 502-03428-00 belongs to Fives Giddings & Lewis PIC900 CNC I/O communication family. Compatible with PIC900 CPU and distributed field I/O modules. Widely deployed on heavy Fives horizontal boring mills.

Function

Function description: 502-03428-00 is I/O communication board manufactured by Fives Group (Giddings & Lewis). It serves as the communication bridge between CNC main processor and remote I/O modules. It packages PLC command data and transmits to field I/O nodes, receives switch and sensor feedback data and forwards to CNC CPU. Built-in parity check detects transmission errors to prevent false I/O triggering in noisy industrial environments. It is legacy I/O communication spare for heavy CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off rack +5V backplane power. Insert 502-03428-00 board into rack slot and secure gold finger connector. Connect field communication cable to serial terminal block. Configure remote I/O node addresses via Fives CNC software. Restore power, verify COM and LINK LED indicators and test remote I/O data exchange.

Interface

Interface list: Backplane gold finger connector, serial communication screw terminal block,on-board POWER / COM / LINK / FAULT LED indicators for Fives Group 502-03428-00.

Diagnostic

Troubleshooting: No communication with remote I/O: Check serial cable wiring, terminal termination or damaged communication transceiver. FAULT LED lit: Parity error, link disconnection or backplane bus communication failure. Intermittent I/O loss: Electromagnetic interference, improper cable shielding or aging communication chip.
