🔧 Installation and Replacement Notes
Before installing a replacement IC693CPU374-GV, verify the complete model number, firmware version, existing rack configuration, and application compatibility.
🔧 Confirm that the controller uses the Series 90-30 platform.
🔧 Verify the installed CPU model before replacement.
🔧 Back up the PLC program and configuration before removing the existing CPU.
🔧 Record the Ethernet IP configuration and network settings.
🔧 Check battery condition and memory retention requirements.
🔧 Install the module in the correct CPU position on the baseplate.
🔧 Verify the 5 VDC power supply capacity.
🔧 Configure Ethernet communication after installation.
🔧 Confirm communication with I/O modules and connected supervisory equipment.
🔧 Test the control program and field I/O before returning the system to normal operation.
⚠️ The two Ethernet ports are part of one embedded Ethernet interface and normally share one IP address. The ports should not be connected in a way that creates a network loop.
