(4) Sample program on the connected device side
The program example of the connected device accessing the L02CPU in the E71-connected station is described.
In this program, data of D0 to D4 (five points) in the L02CPU in the E71-connected station are read with an A-
compatible 1E frame command (01: Batch read in word units). The following are basic operation procedures:
• Sending a command with the line disconnected (Connect the line. After completing the connection, the E71
sends a command.)
• Reconnecting the line with it connected (Disconnect the line. After the disconnection is completed, reconnect
it.)
Remark
The following is an outline of how to compile a program created using Microsoft
• Start Visual Basic
• Create a project. From [File][New][Project], select "Visual Basic Project" in "Project Types" and "Windows
Application" in "Templates", and set the project name (e.g. AJSAMP) and location.
• Create a form and a program. Use the toolbox "Button" to create the sample window shown below (Form1.vb) and
create a program referring to the sample program.
• On the Build menu, click Build Solution to create an execution file (AJSAMP.EXE).
• Exit the Visual Basic
• Execute the AJSAMP.EXE.
