CommServerUA: Redundant, Multi-protocol, Multi-channel OPC UA Server

Home

Welcome to CAS CommServer UA™ - a key to to manage data transfer using OPC Unified Architecture.

CAS CommServer UA™ is a package of communication software to manage data transfer. It’s a fully configurable OPC Unified Architecture server that provides a multi-protocol, multi-medium and multi-channel redundant access to physical process control device data. To ensure short response time and effective utilization of the physical device communication channels throughput, a unique scan on demand algorithm was implemented. CommServer software provides:

  • Integration of production supervision systems (MES, SCADA) with management systems of operations and supplies in an enterprise (ERP, SAP, CRM).

  • Building of communication basing on a uniform standard.

  • Optimization of communication infrastructure utilization of visualization and supervision systems, e.g.:

    • Reduction of GPRS broadcast costs by about 80%

    • Increase of radio communication systems efficiency by over 600%

  • Considerably easier (cheaper) extension and connection of next objects.

  • Increase of functionalities and efficiencies of the existing systems.

  • Creation of OPC UA servers for non-standard (own) protocols.

Main Features

Multi-protocols (new protocols can be added by plug-ins)

Protocol-independent - ones user has defined the process tags and scanning rules, the protocol can be changed easily without any change of the previous configuration

Multi-link and redundancy capabilities (physical devices can be accessed using different protocols, channels, seg-ments and interfaces coupled together in virtual communication pipes)

Advanced polling algorithm - scanning on demand – minimizes utilization of the physical data communication chan-nels

Diagnostic information is provided by OPC tags and a management console

Implementation of a watchdog mechanism that prevents deadlock in case of faulty configuration or malfunction

Significant information are logged in Windows Application Log

It takes the advantages of the most recent technology -.NET Framework
