Hi there,
I am an experienced control and automation engineer. I design from concepts, build, program and commission automation processes.
Having seen your video, without wiring diagram, no-one can reprogram the PLC. If you can spend time drawing it up, you have to trace all wires that connects to the PLC inputs and outputs.
Also, if you can provide details of all components which are connected to the PLC, if you choose to work with me, I can send you a document template for you to fill. Also, I will need an experienced electrician at your site to help with it, as there will be some backward and forward in our discussions and looking at details..
This will be a development kind of project as we have to work as team to identify and control all the processes.
Not sure if it can be done within your budget, so it would be good to chat here to clarify and understand the exact scope of work.
I can fix this for you, but require a lot of work, not just programming, frequent testing to get the sequence right.
I am keen to hear from you, otherwise good luck with your project. Sometimes, it can be challenging to choose the right candidate. So thank you for taking the time to consider me.
Kind regards,
Gopal
