Hi, In properties of my F-CPU is "Default monitoring time for central F-I/O". What is it exactly? I mean, what is it used for? Regards |

Hello, Perhaps the following topic might help: SIMATIC Safety - Configuring and Programming "Default F-monitoring time" parameter Configure the "Default F-monitoring time" for monitoring the communication between the F-CPU and F-I/O. You can adjust the F-monitoring time via the following parameters: ● "Default F-monitoring time for central F-I/O" ● "Default F-monitoring time for F-I/O of this interface" The default F-monitoring time for the central F-I/O acts on the F-I/O that is arranged centrally, i.e. near the F-CPU. You set this parameter in the properties of the F-CPU (select F-CPU, then select "Properties > Fail-safe > F-parameters"). The default F-monitoring time for the F-I/O of this interface acts on the F-I/O that is assigned to this interface of the F-CPU (PROFIBUS or PROFINET). You change this parameter in the properties of the relevant interface (selection of the interface in the "Device view" tab, then "F-parameters"). The various settings available allow you to flexibly adapt the F-monitoring time to the conditions of your F-system, for example to take account of different bus cycles. |

Thanks for your reply. This is just configuration of this parameter but I'm looking for explanation how it works, what exactly means this monitoring time. |

This is watchdog for central F-IOs. If the do not answer in between configured time, CPU goes to stop. |
