Dear all,
we have a SIMOCODE that is used to turn on/off some important pumps in the factory.
Communication is via PROFINET.
SW is TIA Portal.
We control in via HMI. Starting and stopping is working perfectly.
But we need the Simocode to keep the state of the command as it is in case of communication fault.
So, in other words if there is a communication fault and contactor was closed (pump was running), we want it to continue to run despite the communication fault.
We tried few solutions we recieved from Siemens support (disable watchdog, enable external fault and link it with bus fault, automatic reset of fault) and nothing worked.
So if anyone has ever done something similar, it would be really helpfull.
Thanks in advance!
