Compatible Modules & Predecessors

• F8650X / F8652X — Safe Central CPU Modules (primary pairing)
• F8651X / F8653X — Non-Safe Central CPU Modules
• F8627 — Predecessor communication module (still available in portfolio)
• F8628 / F8628X — PROFIBUS DP communication modules

Installation Guide

1. Slot Assignment: Install the F8627X into an available slot in the central module subrack. Each central module supports up to 5 F8627X / F8628X communication modules.
2. CPU Compatibility: Verify the host CPU is an F8650X, F8652X, F8651X, or F8653X with operating system BS41q/51q V7.0-8 or later. ELOP II programming via Ethernet requires ELOP II V4.1 or newer.
3. Ethernet Connection: Connect a standard Cat5e/Cat6 cable to the RJ45 port. For redundant SafeEthernet, install a second F8627X and configure redundant network paths.
4. Bus Station Numbering: When using Ethernet, the central module's bus station number can be set from 1 to 99 (vs. 1–31 for RS485-only). Configure switches S1-6/S1-7 on the F8650X/F8652X accordingly.
5. Network Configuration: Use ELOP II software to configure IP addresses, protocol parameters (SafeEthernet, MODBUS-TCP, OPC), and redundancy settings.
6. Communication Path: Data flows from the central module → backplane bus → F8627X → Ethernet network, and vice versa. No direct Ethernet port exists on the CPU itself.
7. LED Verification: Monitor the module status LEDs and the central module's diagnostic display to confirm successful network link and protocol handshake.

Selection Tips

• Protocol Requirements: Choose F8627X if you need SafeEthernet, OPC DA/A&E, MODBUS-TCP, or ELOP II over Ethernet. For PROFIBUS DP, select the F8628X instead.
• Redundancy: For critical safety networks, deploy two F8627X modules with redundant Ethernet switches to eliminate single points of failure in the communication path.
• Software Version: Confirm your ELOP II engineering station is V4.1 or newer. Older versions do not support Ethernet-based programming and diagnostics.
• Network Segregation: Separate SafeEthernet traffic from standard IT traffic using VLANs or dedicated safety network segments to maintain SIL integrity and reduce latency.
• Existing Systems: If you already have F8627 (non-X) modules, the F8627X is a direct functional upgrade with additional protocol support. Both can coexist in the same system.

Frequently Asked Questions (FAQ)

Q1: Is the F8627X a CPU or an I/O module?
A: Neither. The F8627X is a dedicated Ethernet communication module. It does not execute safety logic or process field I/O. It serves as the network gateway between the H41q/H51q central module (CPU) and external Ethernet-based systems.

Q2: Can I use the F8627X with older F8650 (non-X) CPUs?
A: The F8627X is designed for the F8650X / F8652X / F8651X / F8653X CPU series. While physical compatibility may exist, full feature support (especially ELOP II TCP and enhanced bus station numbering) requires the newer X-series CPUs with OS V7.0-8 or later. Always verify compatibility in the HIMA system manual.

Q3: What is the difference between F8627 and F8627X?
A: The F8627X is the enhanced successor to the F8627. It adds support for OPC A&E, MODBUS-TCP slave, and ELOP II programming via Ethernet (from V4.1). The older F8627 remains available in the HIMA portfolio for legacy systems.

Q4: How many F8627X modules can I install per CPU?
A: Each central module slot can accommodate up to 5 F8627X or F8628X communication modules (or 3 F8621/A coprocessor modules) in the central module subrack.

Q5: Does the F8627X provide galvanic isolation?
A: The module communicates with the CPU via the internal backplane bus. The Ethernet RJ45 port connects to the external network. For installations requiring enhanced isolation between safety and IT networks, use approved industrial Ethernet isolators or media converters as specified in your safety concept.

Q6: What is the warranty period?
A: We provide a standard 12-month warranty for all new and original HIMA products.
