In distributed safety networks (e.g., one F-CPU talking to multiple F-devices over PROFIsafe), Update 1 fixes a potential drift in the blocks’ watchdog timers.
Restart your PC immediately after the installation finishes. Why Install Update 1?
Ensuring the software version aligns with the hardware ensures the safety system is properly validated. Installation and Requirements , indicating that this software is strictly for
| Issue ID | Description | Impact | |----------|-------------|--------| | | F‑CPU in redundant mode (H-system) would incorrectly generate a safety shutdown after a non-safety IO card replacement. | High – fixed in Upd1. | | F‑LIB‑451 | F_ACK_GL block in F‑library V5.5 SP13 caused an internal watchdog overflow when ack signals arrived faster than 50ms. | Medium – fixed via timing parameter adjustment. | | PROFIsafe‑211 | Some ET 200SP F‑DI modules showed “F‑destination address mismatch” after power cycle, despite correct configuration. | High – fixed by updating the F‑parameter editor’s CRC calculation. |
The installer will request a restart. Do not postpone – some F-drivers load at kernel level.
Update wisely, and keep your factory safe.
If your safety program signature changes unexpectedly after updating, perform a with memory reset options enabled in your test environment before deploying to production.
