Connecting to Siemens S7-1200 and S7-1500

Posted by Peggie Wong, Last modified by Peggie Wong on 10/20/2017 09:37 AM

The following considerations, and configuration changes, must be made when connecting to the S7-1200 and S7-1500 devices

  1. Only global DBs can be accessed
  2. The optimized block access must be turned off
  3. The access level must be "full" and the "connection mechanism" must allow GET/PUT
  4. No read/write to TM/CT areas
