TOP Server Modbus TCP Ethernet Client/Server OPC Driver Details
High-Performance Connectivity for Modbus TCP Devices
The Modbus TCP Ethernet driver works in conjunction with TOP Server to provide data exchange between OPC UA, OPC DA, SuiteLink and DDE clients and PLCs using the Modbus TCP Ethernet protocol.
This driver implements both client and server capabilities in the same driver, allowing communication with both server devices (PLCs, RTUs, other control and field devices) and client devices or systems (HMIs, SCADAs, DCS, PLCs, etc). Data acquisition is optimized based on upstream client demand while data integrity is ensured using extensive error handling.
The Modbus Ethernet driver also features direct integration with Modicon Concept and ProWORX programming packages, allowing users to directly import the tags from the PLC into TOP Server.
Modbus TCP Ethernet
This driver is available in the following
TOP Server driver suites:
TOP Server Manufacturing Suite
