Xmodbus OPC Server database file
• The Communication dialog box will redisplay as shown below with the name of
the device in the Device Name field.
7. Populate OPC Server tag database with attributes selected in the Modbus Interface File
(.MIF file):
• Refer to the following display.
• Check the box Populate ViZapp and Server Tag lists by clicking on it and then
select the Modbus Interface File PIDLAB from the Available MIF Files list at he
bottom.
 By doing this you can populate the OPC Server tag database with tags that will be
automatically created from the attributes defined in the MIF file (attributes added to
your Configured List blocks in the strategy). This will save a tremendous amount of
engineering time as you do not have to create each tag manually.
 This will also create a list of Tags in the VizApp Configurator automatically. These
tags can be used to add graphic objects to your instrument documents and display
documents.
