Hello apiplc; When you use D_ACT_DP to re-activate a deactivated slave, it takes the instruction a few scan cycles to bring the slave back up. During that time the F-program could interpret the unknown activation status of the F-I/O modules as a fault and declare an error until the module is fully operational, leading to a temporary passivation. One alternative you could look at is Configuration Control, it works particularly well with F-IO, blocking the f;lashing of fault LEDs when the user deactivaytes and reactivates them: - What should you watch for with configuration control (option handling) with fail-safe controllers S7-1200 and S7-1500? https://support.industry.siemens.com/cs/ww/en/view/109481852 The screenshot below is from the SIMATIC Industrial Software SIMATIC Safety - Configuring and Programming manual showing some uses of Configuration control for F-IOs: https://support.industry.siemens.com/cs/ch/en/view/54110126/115694764811 Hope this helps, Daniel Chartier |
