3. Functional Description
3.1 Real-Time Control
3.2 Redundancy Operation
Hot-Standby (HSB): Primary and backup CPUs run in parallel, mirroring program state and I/O data.
Bumpless Transfer: Automatic switch to backup CPU within milliseconds upon primary failure (hardware/software).
Redundancy Link: Requires IC698RMX016 module for high-speed data synchronization between redundant racks.
3.3 Communication Functions
Ethernet: Supports Modbus/TCP, EGD (Ethernet Global Data), SRTP (Secure Real-Time Protocol), and web/FTP server.
Serial: Connects to HMIs, programmers, or third-party devices via Modbus RTU or SNP protocol.
Firmware Upgrade: Updates via RS-232/RS-485 or Ethernet ports.
4. Installation & Wiring
4.1 Rack Mounting
Insert the IC698CRE040 into a 6U VME64 rack slot (RX7i backplane).
Secure the module with front-panel screws.
Ensure proper grounding of the rack and module.
4.2 Port Connections
Ethernet: Connect CAT5e/CAT6 cable to ETH1/ETH2 ports (10/100 Mbps).
Serial: Connect RS-232/RS-485 devices to COM1/COM2/COM3 (DB9 connectors).
Redundancy: Connect fiber-optic cable (IC698ACC320) or Ethernet cable to redundant CPU.
4.3 Battery Installation
Use IC698ACC701 (smart lithium battery) for memory backup.
Install battery in the module’s battery slot; replace every 3–5 years.
5. Programming & Configuration
5.1 Software
5.2 Configuration Steps
Create a new RX7i project in Machine Edition.
Select IC698CRE040 as the CPU model.
Configure memory allocation, communication ports, and redundancy settings.
Download the program to the CPU via Ethernet or serial port.
5.3 Redundancy Configuration
Add two IC698CRE040 CPUs (primary/backup) and two IC698RMX016 modules to the project.
Configure redundancy link (fiber or Ethernet) and synchronization parameters.
Enable bumpless transfer and data mirroring in the software.
