Tol-O-Matic is new to the controls world, however, they did a pretty good job with it. It is a big bulky, and the GUI is a bit rough, but it is good quality. Tol-O-Matic is a very good company to do business with.
They have made the leap where others should be going for Integrating the Motion Controller & PLC Control into the same package. They also use the latest & greatest servo algorithms so tunning is very easy.
I am not sure if they released MODBUS coms for it yet for use with off the shelf OITs. (Operator Interface Terminals).
You will probably pay a bit more for the Tol-O-Matic system than others, but I guarantee that you will get service & support.
If it does the functionality that you need, then I would say try it. If your using their actuators, better yet, because this it will come configured for your system.
