4. Installation

4.1 Rack Installation

1. Power off the RX7i rack.

2. Insert the IC698CRE040-HN into the CPU slot (typically the leftmost slot).

3. Push firmly until the module seats into the VME64 backplane connector.

4. Secure the module with front‑panel screws.

4.2 Redundancy Setup (Hot Standby)

1. Install two IC698CRE040‑HN CPUs in separate racks.

2. Install one IC698RMX016 Redundancy Memory Xchange module per rack.

3. Connect the RMX modules via fiber or copper redundancy link.

4. Configure redundancy in Proficy Machine Edition / Logic Developer software.

5. Communication Interfaces

5.1 Ethernet Ports (ETH1, ETH2)

• Speed: 10/100 Mbps, full‑duplex, auto‑negotiation

• Protocols: Modbus/TCP, EGD, SRTP, TCP/IP

• Connections: Up to 16 combined web server/FTP connections

• Redundant IP: User‑configurable for EGD data exchange

5.2 Serial Ports (COM1, COM2)

• Modes: RS‑232 or RS‑485 (software‑selectable)

• Protocols: Modbus RTU (Slave), SNP, Serial I/O

• Use Cases: Programming, HMI connection, legacy device communication

5.3 Station Manager Port

• Function: Local configuration, firmware updates, diagnostics

6. Operation

6.1 Power‑On

1. Apply power to the RX7i rack.

2. Check front‑panel LEDs:

   • RUN: Green = CPU executing program

   • FAULT: Red = error (CPU, I/O, or communication fault)

   • ETH1/ETH2: Blinking = network activity

6.2 Normal Operation

• Executes user program and updates I/O every scan cycle.

• Maintains real‑time clock and battery‑backed memory.

• Communicates with HMIs, SCADA, and other controllers via Ethernet/serial.

7. Programming

7.1 Software

• Use Proficy Machine Edition or Logic Developer (Emerson Automation Solutions).

7.2 Supported Languages

• Ladder Diagram (LD)

• Structured Text (ST)

• Function Block Diagram (FBD)

• C Language

7.3 Program Structure

• Blocks: Up to 512 program blocks

• Size: 128 KB maximum per block

• Memory: %W reference table for bulk memory access

8. Protection & Diagnostics

8.1 Error Conditions

• CPU Fault: Hardware/software error; check firmware and program.

• I/O Fault: Missing/faulty I/O module; inspect backplane and modules.

• Communication Fault: Network/serial link failure; check cables and settings.

8.2 LED Indicators

9. Maintenance

9.1 Regular Checks

• Monthly: Verify LED status, clean dust from vents.

• Quarterly: Check cable connections, update firmware if needed.

• Annually: Inspect battery (replace every 3–5 years).

9.2 Troubleshooting

10. Warranty & Support

• Warranty: 1‑year manufacturer’s warranty against defects.

• Support: Contact Emerson Automation Solutions for technical assistance.

11. Safety Precautions

• Disconnect power before installation, wiring, or maintenance.

• Do not operate outside the 0 °C to +55 °C temperature range.

• Ensure proper grounding to prevent electrical noise and shock hazards.

• Keep vents clear to avoid overheating.
