The RS-232 communication parameters for the ISaGRAF WinCE ViewPAC MUST be set to the same serial
communication parameters for the development PC. For the ISaGRAF WinCE ViewPAC (serial port
communications), the default parameters for COM3 (RS-232) port are:
(Please refer to Appendix A.2 to setup COM3 as Modbus RTU slave port)
Debug the Link
Before you can download the project to the PAC, you must first verify that your PC and the PAC system
are communicating with each other. To verify proper communication, click on the "Debug" icon in the
"ISaGRAF Programs" window as shown below.
If the development PC and the PAC system are communicating properly with each other, the following
window displayed below will appear (or if a program is already loaded in the controller system, the
name of the project will be displayed with the word "active" following it.
If the message in the "ISaGRAF Debugger" says "Disconnected", it means that the development PC and
the controller system have not established communications with each other. The most common causes
for this problem is either the serial port cable not being properly configured, or the development PC’s
serial port communications
DO NOT match that of the ViewPAC system.
You may have to either change the serial port communication settings for the development PC (which
may require changing a BIOS setting) or change the "Serial Link Parameters" in the ISaGRAF program.
If there is a project already loaded in the PAC system you will need to stop that project before you can
download the example project. Click on the "STOP" icon to halt any applications that may be running.
