Dear friends,

I want to write principle software for PLC.
By using this software, user will write its own
application software.
So to write such type of software, what information should i require from PLC.
(Any hardware or parameter numbers)
As i am writing PLC application softwares for various kind of machines.
Basic idea behind this, I want to eliminate ladder form and statements list form from it.

Hope you will have an answer.

Thanks.....

 

But Ladder format is required in most plants in order to be compatible with the technicians and electricians who will be servicing it.

As far as I know there is only one PLC source that gives you the access to write native code rather than _their_ choice of weird and wonderful user languages. Some do offer, for example C modules that you can use for special functions.
I write logic in C. Standardization is a big factor! Now if the PLC wendors would actually standardize........

B&R PLC provides Ladder, SFC, IL, ST, and ANSI-C (GNU C integrated). Developer can really create a specific programming environment for his customer.
