I/O modules

This communications coprocessor module handles network communication for GE Series 90-70 PLCs. It offloads messaging tasks from the main CPU to improve system performance. Therefore, this component supports factory-wide data exchange and remote monitoring.

Physical Dimensions and Weight Specifications

The GE IC697CMM711 occupies one standard slot in the Series 90-70 rack. Its housing measures 220 mm in depth for backplane connectivity. The module weighs approximately 0.48 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The GE IC697CMM711 provides one RS-232 port for local programming access. A second RS-485 port supports multidrop communication with field devices. The front panel carries an Ethernet port for TCP/IP connectivity. Hence, users can connect this module to plant-wide networks directly.

Component Count and Onboard Memory

This coprocessor module contains one main board with a 16-bit microprocessor. The board holds 256 KB of dual-port RAM for data exchange. You will also find 512 KB of flash memory for firmware storage. An onboard real-time clock timestamps all diagnostic messages.

Energy Storage and Power Consumption

The GE IC697CMM711 draws 500 mA from the 5V backplane supply. A small supercapacitor retains the real-time clock for 72 hours. This storage maintains timestamp continuity during brief power interruptions. Therefore, diagnostic logs remain accurate after system restarts.

Communication Performance and Load Reduction

The module processes up to 400 messages per second independently. It supports simultaneous connections to 16 remote devices. This coprocessor handles all network traffic without CPU intervention. Consequently, the main processor focuses entirely on control logic execution.
