Peter-
Thanks so much for chiming in. I have been studing the things you have written about Modbus. I have also watched several of your videos. I would prefer to use the legacy interface.
Can you please explain to me with an example how to use GetInput(*) and SetModOutput(*,*)?
I dont think that I can really wrap my head around this until I see how they are used in an example.
I know you are very busy, but if it make a difference, everytime anyone (like you and Hood) helps me get closer, you are helping others get closer in the future also, as I am diocumenting my turret conversion here
http://www.cnczone.com/forums/hardinge_lathes/129658-chnc_turret_plc_conversion_log.html in great detail.
My goal is to doccument the process so throughly, that anyone in the future can do the same or simmilar with very little research or effort. I find it very frustrating, that I am having to "reinvent the wheel" I have found that everyone who has done this in the past has left large or small holes in their postings about how they did it. these holes are not easily filled. I am making a post that leaves NOTHING out. I want the next guy to be able to buy the right parts, wire them up, plug in my settings and have it work. I hope the next person does not need to spend weeks trying to tease enough information out of people/books/wikis to get it functional.
We should be building upon each others expierence and knowledge, not relearning the same stuff over and over again.
Ok, I'm done ranting now....
