Citect

[poppachoppa]

Hi all,
I am trying to take a piece of data from one device (PLC) and write it to another device (Eurotherm) using Citect as the medium. I can do this sucessfully using an event, but I'd like it to happen every second without the need for a trigger. Thanks for the help.

You can call a cicode function at startup. In the cicode function have a loop that does not end (While true do) and in the loop include a sleep statement

Thanks Geoff. I'll try that in the morning. Never had to use Cicode before, so should be interesting!

What GeoffC said will work. I've used that in a couple instances.

Your code will look something like this:

INT
FUNCTION
StartupCode();
WHILE 1 DO
Eurotherm_Tag = PLC_Tag;
Sleep(1);
END
Return 0;
END

Then run the Computer Setup Wizard and set the startup function to StartupCode();
