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

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

The Marcom OPC Server Modbus Slave is an OPC server to a SCADA or other application and represents a Modbus slave device to 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 TRE). In this case, remote stations acting as Modbus masters write via the Internet to the Marcom OPC Server Modbus Slave, which then passes the data via the OPC interface to the supervision or data collection systems.
 
 A time-limited version (30 minutes 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 | Supports connections from multiple Modbus Masters via Ethernet network (TCP or UDP) |
|---|---|
| Configuration | Intelligent configurator with automatic detection of address syntax errors |
| OPC Specification | Compliant with OPC Data Access 2.04 specification |
| Traffic Analysis | Analysis and recording of data exchanged on the network (performance analysis)
 Communication diagnostics at the OPC variable level |
| Additional Features | Possibility of byte, word, double word data swap
 Supports block transfer with settable size to optimize communication
 Import/Export of created configurations
