Hello again,

I tried the same program with KTP400 + TIA Portal v15.1 and it seems to work too. I noticed that it simulates the program differently than with TP1200 panel. I attached the demonstration, in which the value change works as I want it to with internal tags.

Thank you very much, that makes sense.

Hi I hawe similar prbelm. I used event Vaulue Change foe changing the screans with activateScrean function. But the screans didnt change. I saw the bit change its value in PLC but nothing happened after. culd anione help with it?

(Basicli what it shuld do is that becouse Basic panels dont hawe Pop-Up windows iam changing screans with the same screan but diferent "po-pup". And this particular shuld be indication that the STOP buton is presed.)

I made the output of this bit be 1 only for an impuls becouse i dot want it to react if it changes to 0 sou it is a quic (1s) impuls. and when i want to go bac there is an aditional merker (taht is also an impuls) witch sud change screans bac.

(this is logic behind the tags. The first line is not important becouse that is something els (also indication but on screan, it isnt used for changing screans))

Using PLC 1215C TIA V17 and KTP 400 Basic

p.s. I dont know if i can or canot ask my own problems in someons elsis post. so sorry if i am asking it in wrong post. but i saw that in tis post was similar problem to mine. so i asked

So i tried Job Mailbox. it dont want to switcvh screans. What happened: when i added impuls nothing hapened. (this is how it looks like)

This is its DB (from tutorial)

(i anabled bouth in HMI conection. i hawe there screan number pointer becouse i nead to know witch screan is active)

and when i tried to to "force" it to true (becouse i thought that positive edge impulse was to short for it to happen this happened)

(to job number it wrote 33 fore some reason) screan still didnt change
