Modbus & Modbus Plus OPC Server


System Requirements

Description

The OPC Server for Modbus PLCs is an OPC 2.0 compliant server that enables data interchange between the DD-Connect RTXHDB OPC Client and Modbus PLCs. The OPC Server provides read access to all basic PLC register types As well, the server supports Concept style floating point analog registers. Communication occurs via Modbus using RS-232 Serial, Modbus Plus using a SA-85 card, or TCP/IP over Ethernet using the Modicon NOE module. Please note that the DD-Connect RTXHDB OPC Client only uses the read access function to store data on the RTXHDB historical database and does not use the write access function. The OPC server is self-optimizing and auto-configuring to provide easy, efficient, and reliable data transfer.
