How do i upgrade the library version
The Modbus Comm Lib for AC800M is a system library in Control Builder. Connect the Library to your projects and then connect the library to your application.
Control Builder already has the latest version of the library that can run on your controller. You CANNOT upgrade to a version that is not already contained in your control builder.
You may also have older versions of the ModbusCommLib in Control Builder, If you are already using an older version, you can upgrade by connecting the new version to the project and then replacing the library in your application.
