SIMOCODE and Profibus loss

AutoGen_941593 Posts: 1 Rating: (0)	Good afternoon, I am designing a plant with around 150 motors for which I am stating that SIMOCODE shall be used in LV switchgears. The process engineer of my client is questioning the reliability of the profibus DP and the behaviour of the Simocode devices in case the Profibus breaks down. So, unless I reassure him about the goodness of the Simocode solutions I will have to arrange all the switchgears in the "traditional" way, with all I/Os wired. What could I tell the client ? Thank you

If Profibus-DP would not be reliable, then it would no longer exist on the market. But if there is any bus-fault, then it could be parameterized in SIMOCODE, if the motor should be tripped or if the motor should keep running. Beside that provides SIMOCODE-DP the possibility, that the motor-feeder can be controlled completely without PLC via a local-control station (via rthe HW in- and outputs of SIMOCODE). Eventually necessary interlockings could be parameterized directly in SIMOCODE and have not to be realized in the PLC => it is still an autonomous system also in the case, when the PLC / Bus fails regards LesPaul
