Hi, when you upload the code from the PLC, what options do you have twhen you go online and monitor whats happening within the code on the PLC. Do you get the monitoring options you get when download the code to the PLC?? Stuart

Hi, i use Siemens (i know you can upload the code from the plc with no comments etc) Beckhoff (no option to upload) and Mitsubishi. I am correct in saying with some PLC's you can upload the code, then you can download that code to go online and monitor whats happening. or can you upload the code, saying if you have no source code and go online at the same time. Just trying to get my terminology correct. Stu

You can upload the code, however in IEC languages (GX IEC Developer or GX Works2 w/Structured Ladder) you will get the upload as IL if the previous downloader did not download the Symbolic Information. If you use GX Developer or GX Works2 with simple ladder you can upload the program and use IL or Ladder to monitor. This is of course only valid if the PLC is not password protected. In that case you cannot upload the program without a password

Thanks for that, much appreciated. I do this i should ask a more general question in general forum about uploading e.g. what you can do, what you can't etc.
