Print Message Box (PRINT)
« on: July 18, 2014, 04:29:34 PM »
I only have a question about the Flags section of the help file. It says that SP114 is on when port 2 is in communication. I am using port 2 of the PLC to communicate but, SP116  is the flag I see comming on and off while I communicate through port 2. The program works well but when I use SP116 not SP114. Am I missing something?

I just checked - SP116 is the Port 2 "Busy bit" for most CPUs.  The 450 "busy bit" for Port 2 is SP114.  I'm guessing you are NOT using a 450.  We'll update the Help.

Yes, you are correct in your observation that you need to look at SP116 for the "busy bit" for Port 2 on an 06, not SP114.  Sorry for the confusion.  Help will get some help.
