Dear Sir ,

We need to map OPC Client Tag- OPC Server is third pary on Modbus TCP Server/Slave .

Our Modbus Modbus Master is RTU system .

Sorry, I am not really understanding.

If you are trying to link to a third party OPC server, then our OPC client driver is built in and should link to any OPC server.

If you are trying to get access to our tag data via OPC, then our OPC server is also built-in but is an added cost item and requires a special installation key. Check the About VTScada icon on the Application Manager to see if it is installed.

Once it the OPC server tag is set up, any client should be able to access our tags.

Hi Had attached picture where it seems that VTSCADA will take data from third part OPC server as OPC client .

In Same SCADA how to Map Modbus Client where data comming on OPC client can be mapped .

We have Modbus Master as PLC .

Need guidance on same

Configure the appropriate input tag (digital, digital status, analog, analog status) to retrieve the value from the OPC Server via an OPC Client Driver.

Then configure a Modbus Slave using a Modbus tag and configure an output tag to write to the appropriate address in the slave. The output tag should use the input tag as the "data source". See the help on an Analog Output tag, specifically the "Data Source" property for more info.
