I came across Curelom Engineering. They claim to be able to do them.
Maybe, but a systems integrator is going to do it by hand. Curelom Engineering uses a software utility.
In the US, they'll run your program through their tools for no charge, but they'll want you to hire an integrator from their partner program to get you the rest of the way.Siemens has a service for converting programs from non-Siemens PLCs.
But it is (very) expensive as far as I know.
You wont find a free tool for converting between PLC brands.
@Ani, can you let us have the Rockwell to GE tool that you are using ?
Thanks in advance !
