Welcome to the Forum!
A small piece of advice as you are new...
I know language barriers can be an issue here but if you are posting a new thread, try to add more specific detail to its title. A one word title like "Pause" is quite vague and could mean anything. It may not immediately attract the attention of someone who might have specific knowledge to answer your questions.
Example...
"PLC Name Here" - How to Pause a Sequential Program?
This will attract Forum members who have knowledge with that PLC or that brand and often someone who knows exactly how to do what you have asked. This is before they even view the thread.
For the contents of your first post...
Again, statements such as "...I'm new in this PLC..." are extremely vague. It could mean you have poor English and are saying you are new to PLCs in general. Or you could be used to other PLCs, but not the one you are currently working with. If misinterpreted, Forum members may think you are a novice, which may not be the case. You need to state which PLC brand and model you are using.
Add as much detail as you can, no matter how insignificant you might think something is. The more detailed your questions are, the more detailed the answers are likely to be. Don't be afraid to ask what you might think are silly questions. The people who ask all the questions in the beginning may appear to be struggling, but they are usually the ones who excel in the end.
Posting the PLC brand and model here might help narrow down what you have asked, but also be clear whether you want to know how to Pause a Sequence itself, within its logic, or do you mean Pause a Program Routine that is running sequentially, cyclically, or periodically?
Or you could be referring to a Sequential Function Chart (SFC) routine?
In short...
Spell it out for us like we are dumb!

George
