"rt advance" does not mean enough. Please specify fully what you are using. Including the version numbers. The Moderator can then move this topic to the conference it belongs as this conference will not help you much.

Also mention which communication method is being used.

As you stated, the "rt advance" can handle 16. Now you go against the rules and try for 17. Would it be possible for you to have some of the PLCs talk to a central PLC and have that central PLC talk to "rt advance" on their behalf?

Hello dhiraj,

do you mean a S7-1200? Please provide the order number of your device and the software version (number) you have, please. Maybe you can show us with a screenshot or something similar what you have already done?
