Ethernet DDE Server Program For FA-M3

Complicated Ethernet communication processes are all handled by the DDE Server Program as long as you have the Ethernet environments and this DDE communication program, and you can concentrate on data of FA-M3

Outline of Feature

With this FA-M3 Ethernet DDE Server Program, you can view and work with data of FA-M3, A programmable logic controller (PLC) by Yokogawa Electric Corp., on any Windows-based Applications supporting the DDE (Dynamic Data Exchange) interface. This allows you to Communicate very easily between a Windows-based application and FA-M3.

You use the DDE Server Program by connecting a Windows PC to the Ethernet module (LE01-ST) of FA-M3 via Ethernet.

System Configuration

• The DDE Server runs every timer tick ( minimum 50msec), and reads the data from FA-M3.
• You can set the Data Update Cycle Time according to data amount, changing speed of process value and CPU capacity.
• You can build the Visual Basic program into macros of MS-Excel worksheet and write data to FA-M3 using DDEInitiate, DDEPoke, and DDETerminate functions of VB program.

Software Environments

Explanation

For example, by only writing '=PLCTCP｜PLC1！"D00001" ' in cell A1 of a MS-Excel's worksheet, you can read data of D00001 from the D-register in the FA-M3 that is assigned as PLC1.

As this DDE Server Program supports the DDE hot-link function, any changes in FA-M3' s data will be automatically reflected onto those in cells of MS-Excel worksheet.
