TOP Server Modbus Plus OPC Driver Details
High-Performance Connectivity for Modbus Plus Devices
The Modbus Plus driver works in conjunction with TOP Server to provide data exchange between OPC UA, OPC DA, SuiteLink and DDE clients and devices supporting the Modbus Plus protocol using a Modbus Plus interface card in the TOP Server PC. The Schneider USB Adapter USB Adapter TSXUSBMBP Revision 2 is supported by this driver for applications where in PC interface cards are not available or possible. If you have USB Adapter TSXUSBMBP Revision 1, which appears as a COM port to the Windows operating system, you can use the Modbus RTU driver. More details in Device Support under Features below.
This driver supports client and server paths simultaneously. The server mode allows the driver to receive data by exception from other Modbus Plus devices acting as clients. Data integrity is ensured using extensive error handling.
The Modbus Plus driver includes direct integration with Modicon Concept and ProWORX programming packages, allowing users to directly import the tags from the PLC into TOP Server.
