The OPC server provides the OPC clients (any advanced SCADA systems) with an access to devices, supporting the MODBUS protocol. To have a trial run of the software product, you can use, absolutely free of charge, 30 tags without any time limit. To handle more than 30 tags, you can use a 30-day fully functional trial period. Key functions Supported protocols: MODBUS RTU, MODBUS TCP, MODBUS ASCII Supported MODBUS functions: 1,2,3,4,5,6,15,16 Supported communication channels: COM port, TCP connection Opportunity to use an extended list of communication channel types (CSD, GPRS, etc.), using the Modem Communication Channel Module special software Opportunity to poll tag groups of the device at varying intervals Interaction with the OPC clients in accordance with the OPC DA specifications, version 2.05a Service operation function (Windows OS Service) Group setting of tags Configuration import/export in the CSV format (with a report file formatting) Ability to survey and view tag values without the OPC client connection Ability to operate at a broadcast address Ability to emulate tag values OPC server operation logging. Features Automatic search for connected devices reduces the configuring time. Configuration import/export into the CSV format significantly accelerates the configuring process. Polling tag values of the device at varying intervals increases the speed of reading of critical parameters. Surveying and viewing tag values without the OPC client connection allows the OPC server to be initially set without application of any additional software. Tag value emulation provides the opportunity to debug projects in the upper level systems without any physical access to metering instruments.
