Hello All,

I know that since I work with S7-1500, my project is full loaded inside the PLC memory, so not only a compiled version of the project like in the past, but all the project, and so also every tag is stored with their comments.

Based on this assumption, correct me if I'm wrong, I can tell that somewhere in the memory of the PLC, there are for all the tags all the comments of each of them.

So my question is: There is a script or a function, or whatever else I can use to show on a page during runtime of a Panel, the tag name plus the tag comment?

I wish to give my customer this opportunity, scroll all the tags and see their comment on a page on the panel, so he can further change values of every tags, but only after he saw what is the comment and so what is the meaning of this tag.

Thanks in advance!

 Hi,

so he can further change values of every tags?? You want him to be able to force tags for example?

what you can do is you make a DB for inputs and DB for outputs exactly same as the IN/OUT tags, then  you copy the PII to the Input DB and the output DB to the PIQ with a help of FC for example. inside your software you have to use the 2 DBs, not the real IO. 

then in your HMI(Comfort panel) you can add watch tabel of these DBs, the tags text and commects can be shown there and if you want to change there values its possible if you disable the FC call through a user defined button and bit.

Hi T_Ebrahem,

thank for your support. Assume that I don't want to do this for the I/O Tags, but for example for Timers. I wish to show the comment of each timers, I can create a DB full of Timers and then use your procedure to let change the timer value for each of them.

Your procedure can let do this? Show the commets of the timers?

Thanks
