Simatic TP170B Time Object

[aldarin]

Hello, Iam still working on Simatic TP170B color operator panel communicating with two S7-300 CPUs on an MPI network. However TP does not have battery backed clock function. Anyway I am reading the clock from one of the CPUs. I can see the clock on the panel as soon as the power is on. Unfortunately I am also handling with the alarm messages and the message buffer holds the time of the TP, the wrong one of course. Could anyone help me to synchronize the clock of the CPU and the TP. I want to use the CPU clock as a basis of my system time. Best Regards.
