Your both constantly calling the main display which is what is causing the screen to flicker.
See net 1 in the original program, every time the PLC scans the logic it is going to load the Main display. (In a Vision unit we are talking every 4-5 mS) You can remove this net.
Also while net 2 works you should have it broken into 4 separate nets. Nets 7,9,11,13,16,18 in the Main routine should also be separated in to multiple nets( you can get abnormal operation with the way you've done it) I didn't check the other subroutines but any where you've done something similar should be broken in to multiple nets.
And why are you calling the displays from the ladder using MB's linked to touch properties?? If you click on the Links & Jumps tab while editing an HMI you can put your display calls there and not have them in your ladder.
Thanks so much but Please i dont understand what to be done, can someone just kindly help me edit this program to see where i made the mistake.

I add first scan display codes at your program.
This codes make every first scan load -Main Display-
I think when you look codes you will understand "what i wanna do"

Good day, please i have been having problem with a program am writing just because i believe it too long so i split it into subroutine but still not working. i checked and followed examples on the program but trying to use it on mine but still not working. Please i need someone to enlighten me on this subroutine, making call and returning to the initial program.
Thanks

Thanks Joe T you are very right, I have the idea but I don't know where and how to start and I go through the examples on the software but not getting the starting point. Please what can be done to this to help my zeal and level?

Thanks, for the subroutine, I worked on it but yet to get the function
I get that now, each logic for each rung.
For the alarm, I will latch the output.
For the comparison, I want to use the output of the 3 sensor to open or close a valve and that was why I did it that way but the fact that it is wrong, kindly advice how to go about it.
Also, for the subroutine, is it that each detector will be design In a subroutine or what ?
Please if you have any written program that you know I can learn from, kindly help attach to aid my learning.
Regards

Thanks for the response, am using a RTD type and the plc am using is V200-18-E1B.
will this also go in with a pressure transmitter and for the output, will i set a coil or just pick ML as the output?
is this correct?
