⚙️ Operating Specifications & Usage Guidelines

The IC693CPU374-GV module must be installed exclusively in slot 1 of a Series 90-30 CPU baseplate. Proper backplane alignment, adherence to electrostatic discharge (ESD) precautions, and verification of firmware compatibility are mandatory prior to installation and power-up.

 

🔌 Power ON / OFF Sequence

• 🔋 Power-UP Sequence:
  1. Ensure the CPU module is firmly inserted into Slot 1 of the CPU baseplate and the backplane connector is fully engaged.
  2. Verify that all field wiring, serial communication cables, and Ethernet patch cords are securely plugged in.
  3. Turn on the main power supply feeding the baseplate rack. The CPU automatically executes an internal power-on self-test (POST).
  4. Monitor front-panel LED indicators (RUN, STOP, OK, PORT 1, LAN) until the system finishes booting and application logic begins execution.
• 📴 Power-DOWN Sequence:
  1. Bring the controlled industrial process to a safe, controlled stop state before powering down the automation system.
  2. Switch off the main power supply unit feeding the Series 90-30 rack.

 

📝 Step-by-Step Normal Operation Procedure

1. Pre-Check: Inspect front-panel status LEDs to ensure OK is solid green, RUN is lit if executing application logic, and no fault indicators are active.
2. Online Monitoring: Connect via programming software over Ethernet or serial link to monitor live register variables, I/O scan health, and PLC sweep times.
3. Network Exchange: The embedded Ethernet port automatically handles SRTP communication, Modbus TCP messaging, and programming connections simultaneously.
4. Data Backup: Periodically back up user logic and configuration files to a compatible memory module or engineering workstation archive.

 

💻 Parameter Configuration & Modification Method

1. Connect an engineering workstation running Proficy Machine Edition (or legacy VersaPro/Cimplicity programming software) to the CPU via the embedded Ethernet port or serial cable.
2. Go online with the target PLC controller and upload or edit the hardware configuration file.
3. Modify CPU parameters, including sweep time limits, memory allocation splits, rack I/O configurations, and embedded TCP/IP IP addresses.
4. Store and validate the updated configuration project directly to the CPU’s non-volatile flash memory storage.

 

❓ Frequently Asked Questions (Q&A)

• Q: What is the main advantage of the IC693CPU374-GV compared to older Series 90-30 CPUs?
  • A: The CPU features an embedded Ethernet port, eliminating the need for a separate rack-mounted Ethernet communication module (such as the IC693CMM321) while providing faster processing speeds and increased memory capacity.
• Q: Can this CPU support both serial and Ethernet programming connections simultaneously?
  • A: Yes. It supports concurrent communication channels, allowing engineers to monitor via Ethernet while utilizing the serial port for legacy operator interfaces or modems.
