Problems to read data from PLC with OPC UA

Hello, I am trying to set up and opc ua connection with and Advantech Module ADAM-6317 to read data from a PLC. I am using FlexSim 22.2.0.

When I put the credentials, it tells me that the conecction is succesful.


When I try to read the variables from a Digital Input of the module, I get this error:

exception: FlexScript exception: VIEW:/active/EmulationProperties2688925552/TabControl/Variables/SplitterX/RightPanel/PropertiesPanel/OPCUAVariableSensor/Browse/BrowseUAConfiguration3206015304/Tags>eventfunctions/OnSelect c: VIEW:/active/EmulationProperties2688925552/TabControl/Variables/SplitterX/RightPanel/PropertiesPanel/OPCUAVariableSensor/Browse/BrowseUAConfiguration3206015304/Tags i: VIEW:/active/EmulationProperties2688925552/TabControl/Variables/SplitterX/RightPanel/PropertiesPanel/OPCUAVariableSensor/Browse/BrowseUAConfiguration3206015304/Tags>items/Objects/Digital_Input


To write data on PLC I don't have any problems. As you can see in this video, I send values to turn on and turn off the light and it's sucessful.


Someone can help me?


Thanks in advance.

Hello Jason!


Yes, when I use other clients (UA EXPERT, Prosys OPC e OPC EXPERT) I don't have problems, just when I try read data using Flexsim to get Digital Input, the options window doesn't even open.

I tried in the 22.1.4 version too.

Does the error appear when you try to browse to the structure to select a nodeID?
