You are correct,One thing you MUST consider !
the hours quoted are from members who have been doing programming for years. They don't have a learning curve.
we don't know your application.
we don't have a scope of work or sequence of events.
we don't know your programming software, interface, or hmi.
we don't know your programming experience and capabilities.
I don't mean to be rude or mean, but you must look at the process, scope of supply and sequence of events, safeties and plc interface to other systems, manual controls, documentation required, commissioning, prove out, and your own capabilities and come up with your own time estimate.
if you quote 50 hrs based on what we tell you and it takes you 60, that's ok, you were close. but if it takes you 200 hrs for example, then that's another matter and I don't know how to over come it because you went by what we would quote based on none of the information I have listed. if we had all the information, our time may have gone up to 200 hours.
as I said, look at all the information and come up with a time frame that you are comfortable with.

I already scheduled time.
