Hi Archie,

Support Questions / Problem reading lenght > 1 in Schneider with modbusDriver

« on: May 10, 2022, 11:23:55 AM »

Dear all

Im having problems with one Schenider PLC subscribing to modbus adresses with lenght > 1, the same code is working well with the other PLCs:

SubscriptionID = DirectCast(Clas, AdvancedHMIDrivers.ModbusTCPCom).Subscribe(40040, 6, 500, AddressOf Me.ClientDataRecived)

and:
 

Public Async Sub ClientDataRecived(Optional sender As Object = Nothing, Optional e As Drivers.Common.PlcComEventArgs = Nothing)
        Try

            Dim Value = Nothing
.............................................

But the ClientDataRecived sub is not even triggered....

In the other hand, this works fine just as expected:

Dim test = DirectCast(Clas, AdvancedHMIDrivers.ModbusTCPCom).Read(40040, 6)

Anyone knows where can it come from? any parameter in the PLC or way to debug the subscription reads to the PLC?

Thanks in advance
