Dear July, A shutdown is initiated when something goes wrong with a failsafe I/O, this could be a parameter of time thats on a edge or a wrong wiring... Normally you could also reset this, please check the failsafe software in the handbook Programmable Controllers S7 F-FHto see how to work with this shutdown. The Shutdown logic responds to an internal diagnostic that has detected a failure by disabling the entire Safety Program (Please note that CPU will remain running). This is configured on the F_SHUTDN SHUTDOWN input. The shutdown logic's F_SHUTDN RESTART input allows you to restart the Safety Program that has been shutdown. Reintegration of I/O may be necessary after this action. See page 2-2 for more information about the F_SHUTDN functions. Please take also in account that you uses the newest software. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
