Description
The HIMA F8650X is the high-performance central processing unit (CPU) for the HIMax safety system. It is designed for large-scale, safety-critical applications requiring maximum availability, high-speed processing, and SIL 3 certification. The “X” designation typically refers to the hardware revision or specific coating for enhanced environmental protection.

Country of Origin
This CPU is engineered and manufactured by HIMA Paul Hildebrandt GmbH in Germany, specifically for the most demanding global safety standards.
Application Fields
The F8650X is the “brain” behind massive safety installations:
- Emergency Shutdown (ESD): Managing thousands of I/O points across oil refineries and LNG terminals.
- Fire & Gas (F&G): Coordinating high-speed detection and suppression logic in offshore platforms.
- Burner Management (BMS): Safe sequencing for large utility-scale boilers.
- Pipeline Protection: High-integrity pressure protection systems (HIPPS).
- Railway Safety: Managing interlocking and signaling logic for high-speed rail networks.
Product Usage Instructions
- Chassis Placement: The F8650X must be installed in the designated CPU slots of the HIMax base plate. For redundant operation, two CPUs are installed side-by-side.
- Network Setup: Use the four integrated Ethernet ports to establish the system bus. It is recommended to use separate networks for the safety-critical safeethernet communication and the general SCADA/HMI communication.
- Programming: Configuration and programming are performed using the SILworX software tool. This allows for logic development in Function Block Diagram (FBD) or Sequential Function Chart (SFC).
- Redundancy Configuration: The HIMax architecture is “X-redundant.” In a redundant pair, if one F8650X fails, the other takes over control seamlessly without interrupting the process.
- Diagnostic Monitoring: Monitor the integrated 7-segment display and LEDs. The display provides specific error codes that can be cross-referenced in the SILworX diagnostic manual.
Product Technical Description
Technically, the F8650X is a “Non-Stop” safety controller. Unlike older safety systems that shut down the process if a controller fault is detected, the HIMax CPU architecture allows for online changes and online testing. This means you can update the safety logic or replace a CPU module without stopping the factory. It utilizes a 1oo2D (1-out-of-2 with diagnostics) internal architecture to ensure that every calculation is verified before an output is set, satisfying the highest safety standards while maintaining maximum plant uptime.
Q&A (Common Questions)
Q: Can I replace an older F8650 with the F8650X? A: Generally, yes. The “X” version is hardware-compatible, but you must ensure that your SILworX software version and the existing system firmware support the newer hardware revision.
Q: Does the CPU require a battery for program storage? A: No, the program is stored in non-volatile Flash memory. However, a battery is typically used to maintain the real-time clock and certain retentive variables during a power loss.
Q: How many I/O modules can a single F8650X manage? A: A single HIMax rack can support up to 15 I/O slots, but the F8650X can manage thousands of I/O points across multiple interconnected racks via safeethernet.
Q: What is the purpose of the 4 Ethernet ports? A: They provide flexibility for physical network separation. You can dedicate ports to peer-to-peer safety communication (safeethernet) while using others for Modbus TCP communication to a DCS.
