Product Introduction

The HIMA F8627X is an Ethernet communication module designed for HIMA PES H41q and H51q safety systems. It provides Ethernet connectivity for SafeEthernet communication, Modbus TCP integration, OPC communication, and ELOP II engineering access through an RJ45 interface.

The module separates communication processing from the main safety CPU, allowing existing HIMA safety controllers to exchange data with other systems and engineering stations. Replacement requires verification of operating system version, network topology, SafeEthernet configuration, and compatibility with installed CPU modules.

Installation & Configuration Guide

 

Stage 1: Pre-Installation Preparation (Approx. 15 minutes)

⚠️ Safety First

  1. Notify plant operations before removing the HIMA communication module.
  2. Confirm the safety system is placed into an approved maintenance condition.
  3. Apply lockout/tagout procedures to cabinet power.
  4. Wait at least 5 minutes for stored energy discharge.
  5. Verify the rack supply voltage is removed before touching the module.

Tools Required

  • ESD wrist strap
  • PH1 screwdriver
  • Digital multimeter
  • Wire labels
  • Smartphone for photos
  • HIMA ELOP II engineering documentation

Data Backup

Before removing the F8627X:

  1. Record:
    • Rack location
    • Slot number
    • Module identification
    • Operating system version
  2. Save communication parameters:
    • IP address
    • Subnet mask
    • Gateway settings
    • SafeEthernet configuration
    • Modbus TCP settings
  3. Photograph:
    • Ethernet cable connections
    • DIP switch settings
    • LED status
    • Rack position

 

Stage 2: Removing the Old Module (Approx. 10 minutes)

  1. Remove cabinet covers if required.
  2. Label Ethernet and HSR communication cables.
  3. Disconnect RJ45 and HSR connections carefully.
  4. Release module retaining screws.
  5. Pull the F8627X straight out from the rack.

Inspect:

  • Backplane connector pins
  • Rack contacts
  • RJ45 connector condition
  • Dust or contamination

⚠️ Note: Keep the original F8627X until communication testing is completed. Legacy HIMA systems often depend on exact network parameters and firmware versions.

 

Stage 3: Installing the New Module (Approx. 15 minutes)

  1. Wear an ESD strap before handling the replacement unit.
  2. Verify:
    • Model: HIMA F8627X
    • System: H41q/H51q
    • Function: Ethernet communication module

⚠️ Configuration Clone — Critical Step

  1. Restore the original communication configuration:
    • IP addressing
    • SafeEthernet node configuration
    • Modbus TCP parameters
    • OPC communication settings
    • HSR redundancy settings
  2. Insert the module into the correct rack position.
  3. Ensure the backplane connector is fully seated.
  4. Tighten retaining screws.
  5. Reconnect Ethernet and redundancy cables.

Self-Checklist

  • Correct model verified
  • Rack position confirmed
  • Network parameters documented
  • Ethernet wiring checked
  • Redundancy connection restored

 

Stage 4: Power-On & Testing (Approx. 20 minutes)

Pre-Power Check

  1. Verify rack 5 VDC supply.
  2. Check Ethernet cable condition.
  3. Confirm network switch port configuration.
  4. Verify IP address allocation.

Power-On Steps

  1. Energize the HIMA rack.
  2. Observe front LED diagnostics.
  3. Connect ELOP II engineering software.
  4. Verify:
    • Module recognition
    • Operating system compatibility
    • Ethernet communication status
    • SafeEthernet connection
  5. Test communication with connected systems.
  6. Confirm process data exchange.

⚠️ Troubleshooting Note

  • No Ethernet communication: Check IP address, subnet configuration, and switch port settings.
  • SafeEthernet fault: Verify node configuration and firmware compatibility.
  • Modbus TCP failure: Confirm TCP port settings and master/slave configuration.

 

Frequently Asked Questions (FAQ)

Can the HIMA be hot-swapped under power?

No. The is a rack-mounted communication module used in a safety system environment. Removing it while powered can interrupt communication paths and affect system operation. Follow the approved HIMA maintenance procedure and isolate power before replacement.

What is the main function of the HIMA ?

The provides Ethernet communication capability for HIMA H41q and H51q systems. It supports SafeEthernet communication, Modbus TCP Slave, OPC communication, and ELOP II programming through Ethernet.

Is the HIMA obsolete?

The belongs to the legacy H41q/H51q platform. It is no longer a current-generation communication module, but many plants continue operating these systems and maintain spare modules to avoid unplanned migration projects.

Can the replace the older F8627 module?

The has the same basic communication role as the F8627, but additional functions require compatible operating system versions. The supports newer functions such as Modbus TCP and ELOP II Ethernet programming when the correct OS version is installed.

Will replacing the erase the safety program?

No. The does not contain the complete safety application logic. However, network configuration, communication parameters, and module operating system compatibility must match the existing system.

Why is the priced differently from newer communication modules?

Legacy safety communication modules are usually sourced from remaining OEM inventory, New Surplus stock, or tested refurbished channels. Price differences depend on condition, documentation, testing results, and availability.

What should I verify before ordering an HIMA ?

Check:

  • HIMA platform: H41q / H51q
  • Exact model:
  • Installed CPU type
  • Operating system version
  • Ethernet network configuration
  • SafeEthernet topology
  • Modbus TCP requirements

A similar communication module may not provide the same protocol support.

How should a surplus module be tested before installation?

A proper inspection process should include:

  1. Verify OEM label and serial number.
  2. Inspect connectors and housing condition.
  3. Test on a genuine HIMA H41q/H51q rack.
  4. Verify 5 VDC operation.
  5. Check Ethernet link status.
  6. Test SafeEthernet or Modbus TCP communication.
  7. Generate a functional test report.

Test photos and records should be retained for maintenance traceability.
