WinTECH Software Newsletter WinTECH Software Newsletter Vol. In response to several requests, WinTECH Software has introduced a slave version of it's modbus ActiveX Control. Each data block definition is configured to represent a range of modbus data corresponding to a particular slave and memory address.
Data written to the data block is automatically updated and made accessible to a connected master.
This control represents the easiest way possible to interface data from a PC application into a modbus system without having to learn the details of the protocol or Windows serial driver interfaces. Several OPC compliant Client and Server applications are now commercially available even while the OPC Foundation is working to complete the Version 2.0 specification. In the course of developing an OPC Server application for one of its customers, WinTECH Software saw the need for a simple low-cost test tool which could be used to test and verify compliance with various OPC designs. All Required OPC Version 1.0 custom interfaces are supported and OPC Client may be used to test each interface supported by the server. OPCSvrSim is an OPC Server application which may be used to simulate data for testing OPC Clients.
