The SCADA 3000 Software contains a C programming utility that allows you to write C
programs, upload/download them to the SCADA 3000, save/load C programs on your com-
puter, compile, run, and start programs in the SCADA 3000. This can be performed while
online through the RS232 serial port or remotely via modem. To access the C Editor, open the
Control Center form and click on the “C” button in the toolbar or choose “C” from the main
menu. The following form will appear:

Program, Save Program, Cut, Copy, Paste, Undo, Syntax Check, Compile Program, Upload Program,
Download Program, and Start/Stop Program.
