Milford, MI January 8, 2004—Sapia Inc. introduces SMTX: an ActiveX control that brings Modbus/TCP Master functionality to Excel, VB 6.0, VC++ and other applications. Within minutes, SMTX allows any compatible application to communicate over a wired or wireless Ethernet network using Modbus/TCP protocol. SMTX features built-in Properties and Test Pages for communicating with Modbus servers at design-time. This feature makes start-up and troubleshooting easy without writing a single line of code! SMTX provides a rich set of properties and methods for configuring the connection and communicating with Modbus server devices at run-time. Talking to a Modbus/TCP server is as simple as calling a function with the necessary arguments. SMTX automatically builds the command, prepends the header, sends the command over the network, and receives and validates the response. The application program just reads and writes simple 16-bit data values. SMTX conforms to all of the Class 1 and Class 2 commands—plus a few additional ones—as specified in the Open Modbus/TCP Specification.Sapia produces a complete line of Modbus software components.
