Marcom OPC Server UA Modbus Slave for TCP/IP and RS485/232 networks. Multi-connection support, advanced diagnostic functions.

**Marcom OPC Server UA Modbus Slave** with TCP and RTU protocol in the same product! A next-generation OPC Server developed in .NET 4.6.2 technology.

The Marcom OPC Server UA Modbus Slave is an OPC UA server for a SCADA or other application and represents a Modbus slave device towards the ethernet network or serial port.

It is the ideal solution for collecting data from remote stations connected to the Internet via GPRS/UMTS with blocked Ethernet ports (e.g., Vodafone or WINDTRE). In this case, the remote stations acting as Modbus masters write via the Internet to the Marcom OPC Server UA Modbus Slave, which then passes the data via the OPC interface to supervision or data collection systems.

A time-limited version (30 minutes of run time) is available for download for complete product testing.

The product is supplied with a licensing system that adapts to all needs: 500 variable license, 1000 variable license, and unlimited variable license. It is always possible to upgrade to a higher category license.

The main features of the OPC Server are:

 

| Connection / Connections | Support for connections from multiple Modbus Masters across an Ethernet network (TCP or UDP) |
|---|---|
| Configuration | Smart configurator with automatic syntax error detection for addresses |
| OPC Specification | **Compliant with OPC Unified Architecture (UA) 1.04 specification** |
| Traffic Analysis | Analysis and recording of data exchanged on the network (performance analysis)
Communication diagnostics at the OPC variable level |
| Security | **Implements opc.tcp and https protocols, includes anonymous access management and user/password access with the ability to set read and write access rights for each user or user group.** |
| Additional features | Possibility to swap byte, word, double word data
Support for block transfer with settable size to optimize communication
Import/Export of created configurations
Writing variables from the OPC Server configuration window |
| Supported Operating Systems | Windows 7/8/10/11 + .Net Framework 4.6.2 |
