Key Functions and Features
Multi-mode Programming & Configuration
- Supports parallel programming (MS‑DOS only), serial port programming, and Ethernet TCP/IP programming.
- BMA function is supported in Windows software v2.2 and later; MS‑DOS software has limited functionality.
Multi-level Data Protection
- When the memory protection key‑switch is locked, only the parallel‑connected programmer can modify programs/configuration.
- Access is controlled by software passwords; battery‑backed memory ensures data retention during power loss.
Flexible Operation Control
- Three‑position RUN/STOP switch supports three modes:
- Run with Output Enabled
- Run with Output Disabled
- Stop
- Operation status can also be remotely controlled via remote programmers and software.
Convenient Status Monitoring
- Seven LED indicators provide real‑time status: module OK, run status, output enable, memory protection, and communication activity for three serial ports.
- Module operation can be monitored without a terminal.
Online Firmware Upgrade
- Connect to a compatible PC via serial port and run the firmware upgrade kit software to complete updates.
- No module disassembly or EPROM replacement is required.
Hot‑swap Battery
- Install the new battery before removing the old one to avoid memory data loss during replacement.
The battery also powers the calendar clock.
Installation & Usage Guidelines
Installation & Operation Rules
- The module can only be installed in Slot 1 of Rack 0 of the Series 90‑70 rack.
- Before installation, set the RUN/STOP switch to STOP, set the memory protection key switch to OFF, and turn off power to the rack.
- When the ambient temperature exceeds 50°C, a 70 CFM forced‑air cooling fan must be installed below Slot 1 of the CPU rack.
- Optional GE original fan assemblies: IC697ACC721 / 724 / 744.
- For serial communication, ports P2 / P3 require a converter (e.g., IC690ACC901 cable kit). Custom cables are available for specific application requirements.
- For Ethernet TCP/IP communication, an IP address must first be assigned to the IC697CMM741 / 742 module, then connect the programming PC to the PLC.
- On power‑up, the CPU verifies module and rack configuration. If the actual configuration does not match the programmed configuration, a fault is reported to the alarm processor and the configured fault response is executed.
- When removing the module, squeeze the plastic retaining clips on the backplane to release from the rack rail, then pull out smoothly along the slot to avoid damaging the backplane connectors.
