Low-cost OPC Server

Acromag has released a very affordable Modbus/TCP Master OPC DA Server to help engineers quickly integrate their Ethernet I/O modules into a control system communicating over Ethernet. The Model ACMBTCP-OPC software package is exclusively for use with Acromag I/O and delivers high-speed connectivity to their BusWorks® and EtherStax® Modbus TCP/IP slave devices via Ethernet for just $199. A free 30-day evaluation version is available.

This OPC software can be used as a data server to any HMI or SCADA package that is OPC compliant or to custom-built Visual Basic/C++ applications. It is compatible with National Instruments LabView®, Wonderware InTouch®, Rockwell RSView®, CitectSCADA®, and many other popular process control software packages. Acromag’s OPC server offers the most reliable, cost effective and comprehensive features list available in the OPC/HMI market today. Unique read/write tag optimization algorithms provide unmatched data transfer speeds between OPC server and hardware devices.

The server has passed the OPC Foundation’s OPC Data Access 3.00 compliance test. This server includes comprehensive, context-sensitive help systems, a Visual Basic OPC client example application with Visual Basic source code, and a pre-built client executable. The software runs on many versions of Microsoft Windows® including XP, Vista, 7, 2003 Server, and 2008 Server. It also supports an unlimited number of OPC clients, devices, or items.

Other key features make this OPC server very easy to use. It has a very user-friendly CSV import/export capability. CSV files for all Acromag Ethernet I/O devices are included with the OPC Server. Further, the software can run as a stand-alone executable or unattended with no login required. A device status dialog provides for convenient diagnostics.
