GridVisLicensesOptional the following extension modules are available for GridVisGridVis licence, item number 51.00.117Graphic programming modulewrite/read ModbusAllows the "read/write modbus" function modulein the graphical programme editor to be used. Thisfunction may be used by measurement devices thatsupport Jasic ® (such as UMG 604, UMG 508etc.). Consequently, measured values are exchangedamongst one another via modbus TCP/IP(port 502) or modbus RTU and processed inJasic ® programmes.GridVis licence, item number 51.00.123Database driver for MySQL /MS-SQL serverEnables data exchange between the GridVis and anSQLServer.

The generic measurementdevices may be integrated into and analysedin reports, graphs and topology. Measured valuearchiving can be configured with the aid of theonline readout. In order for online readout to function,the GridVis software must run at all times.GridVis licence, item number 51.00.121Virtual instrumentAdditional virtual measurement points may beadded. This function allows items such as measurementdevices/measurement points to be addedand thus organised into categories or groups. Theconfiguration allows basic mathematical operationssuch as addition, subtraction, division andmultiplication to be performed.Individual measured values can be linked frommultiple measurement points. The virtual measurementdevices may be integrated into reports, graphsand topology and analysed either historicallyor live.166
