SIL3 Certification and Fail-Safe Execution
The F8627 module is designed for integration in SIL3-certified safety architectures. It supports fail-safe state execution, ensuring that in the event of communication faults or module errors, connected safety controllers revert to predefined safe states. Galvanic isolation between communication interfaces and system backplane enhances resilience against electrical disturbances, while redundant HSR links maintain deterministic synchronization across paired modules.
Frequently Asked Questions
Q: Can the F8627 be hot-swapped during system operation? A: No, the module requires the safety system to be powered down before insertion or removal to avoid communication faults.
Q: What is the redundancy behavior with dual HSR connections? A: Redundant HSR links provide synchronized communication; in case of one link failure, the second maintains continuous data exchange without interruption.
Q: Does the module support firmware upgrades? A: Yes, firmware can be updated via Ethernet, but compatibility must be verified against the installed H41q/H51q system revision.
Field Installation Guidelines
Install the module in designated slots of H41q/H51q racks, occupying 3 HU height.
Ensure RJ-45 Ethernet and RJ-12 HSR cabling are shielded and properly grounded.
Maintain ambient temperature within -25 to +60 deg C for stable operation.
Configure DIP switches before commissioning to set module number and transmission parameters.
Verify LED indicators during startup to confirm link integrity and fault-free operation.
