You can use the Sharp Test Program (sharp_diag.exe), provided with the Sharp TCP/IP communications option, to check your network configuration without starting a CIMPLICITY project. You need to run this program from a command prompt window for your project.
To open a command prompt window for your project:
Open your project in the CIMPLICITY Workbench.
Select Command Prompt... from the Tools menu.
Enter the command you want at the MS-DOS prompt in the Command Prompt window.
If the command succeeds a series of information messages displays
If the command fails, then an appropriate error message displays. In this case, check your Ethernet connections, ladder logic and your computer configuration to ensure that all are configured correctly. Any error or inconsistency will prevent successful communication.
You can find detailed information about the Sharp PLC communication commands in the "New Satellite JW series" Programmable Controller A User's Manual Ethernet Interface Module type JW-50CM Rev 1.0 manual.
Verify the PLC Connection.
