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?

What CPU (05, 06, 250, 260, 450, etc.)?

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.

I'm currently using CPU 06... and thanks for the clarification

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.
