Hi-ya Jim, I (we) appreciate the feedback.. good to hear. I am a bit concerned about the TON that is initialized by SM0.1 - it will be sure be helpful to see a screen-capture of the code segment. The best all-in-one reference is this manual:

Gentlemen, Thanks again for the replies. The units I have been having communication issues with are S7-216 models. I do have user manuals for the 216 through 226 models. Our company has an Automation Department that does most programming, but unfortunately through mergers and retirements the support for the older S7 is non-existent. The plants I work at have a few S7's, some 545's, AB SLC500, AB RSLogix, even an ancient TI 305. I have a Tech position which covers electrical, mechanical, PLC and pneumatic controls and such. I have had programming training classes, but limited actual experience since I maintain the systems and don't make many changes. I'm the classic example of the Jack of All Trades, Master of None. I have tested the Comm Ports by Upload/Download and the Program Status button, and did learn to place the PLC in Stop so I could connect to Port 1 which is set up in the Freeport Mode. Attached is a screen shot of the timer. Jim Attachmenttimer.pdf (305 Downloads) |
