Hi, please check the following manual: SIMATIC Distributed I/O System Fail-Safe Engineering ET 200S Distributed I/O SystemIn chapter 5 Diagnostics you will find information about Fail-safe vaule output (Page 54) and F-module with inputs (Page 55). i.E. for INPUTS you can read: If a communication error is detected, the current process values remain set at the inputs of the F module and the channels are not passivated. The current process values are sent to the F-CPU and are passivated in the F-CPU. Regards, Towome |

hi calyon, the ET200s modules give the safe value 0. see the manual already provided, chapter 5.1
In other F-modules you have other possibilities, like ET200M. in properties of the module you can set what the module should do. you can say: -use substitute value 0 -keep last valid value SIMATIC Automation System S7-300 ET 200M Distributed I/O Device Fail-safe signal modules in chapter 6.1.3 you see how to handle this.
hope this helps, regards, |
