• I can't set up the correct display of data on the graph for the characteristics of the motor Current, moment.
• I was able to implement the transmission of auxiliary signals. (Reading the words of the state, current readings of current, torque, speed) through the LAD language in Tia Portal V15.
• I announced these addresses in NI OPC server and implemented them in LabVIEW, but I don't know how to make a competent display.

Hello АРН1

It s not clear to me where is your question/problem?

So If I understand correctly , youget values from the drive to the S7PLC. Here you use a OPC connection to Labview and here you want to show the values in your visualisation; is this correct?

(Drive-> S7-PLC->OPC->Visualisation)

So the S7 PLC acts like a OPC UA Client correct?

Do you ge tthe corrrect values in PLc DB?

Or is it completly different situation?

Perhaps a few more details would be nice

If I am not mistaken, then according to the nameplate on the engine at a maximum of 1350 rpm, the rated current is 0.42 Arms.

But on the graph in LabVIEW, at any given speeds, it jumps 9990,00-9998,00.

The S7 PLC acts as an OPC UA client, yes

Maybe the types don't match, what I get from the PLC should match the LabVIEW type.

Hello АРН1

If I can see it correctly you are using Word values for data communication between the PLC and the OPC Server. Perhaps there is a kind of byte swap??

So if you have the correct value in the Datablock in PLC and in the OPC Server its the wrong value then It could only be a wrong addressing or byteswap..
