(OPC Server for modbus)
mbOPCSvr is designed to provide a generic interface between modbus slave
devices and Windows applications operating as OPC Clients. MbOPCsvr operates as a standard
Windows Multiple Document Interface, (MDI), application. Each document represents a block
of data from an addressed modbus slave and is scanned independently based on a user defined
clock interval. Each data item configured within a document may be addressed by one or more
OPC Client applications. As new data is read from the modbus slave, the OPC Tags are
automatically updated. Multiple slaves may be attached to the PC and made available
to OPC from any of nine serial ports or via a modbus/TCP connection.
Using mbOPCsvr, you may open multiple documents to represent modbus data collected from
a slave device. Each document is scanned according to the defined rate and made automatically
made available to any compatible OPC Client application.
Each data point defined within a document is represented by a tag name associating the
PC Com Port, Slave ID, and Modbus Address. Register data may be scanned from the slave
as integer, unsigned, floating-point, or scaled values.
