Hello everyone

I have cpu 1214c and ktp700 hmi.

Also I have 5 valves that must be controled according relative  timer. Operator can select which valves will be opened and adjust hour and second by hmi. my hmi page is attached.

I used relative timer in this library (https://support.industry.siemens.com/cs/document/78788733/how-can-timers-be-programmed-in-a-s7-1200-in-the-dtl-time-format?dti=0&lc=en-WW).

I should make 5 tags in every row of table to connect these to every valves, so for 50 rows of table, I must make 250 tags!!! What should I do?

A very nice link you have there - thanks for sharing.

I am a bit reluctant to help -
you do not seem to rate people who try to help you.

Could you explain where you get the 250 variables?
Which values in the table can be changed and which are fixed?

My assumptions -
(a) The schedule times are fixed at 10 minute increments
(b) Any of the valves can be switched at any of the 10 minute increments.

Next -
(a) What happens if the valve stay on time is longer than the 10 minutes?

Last thoughts -
For the PLC to handle the 250 tags is not a problem. Best to order those inside arrays. If we assume there are 5 arrays each with 50 tags, then the KTP700 only needs to be configured for 5 tags (the first element in the array). The 5 tags is much better to work with for the KTP700, but to untangle those for to expand to 50 rows, is going to be work. It can be done.

What worries me more is that the user needs to edit 50 rows of data... that is too much. Consider if there is some way to make the job easier for the user.

I think every expert in this forum, that have a lot of stars, they do not need my rate, because they help to everything for conscience, they love helping  to other, but we should encourage them by rate.
