Reviews for CPUs (Remote & Expansion)

Recently did a controller upgrade on a machine from shcnieder electric modicon controller to the productivity 3000 series with this processor. My experience has been quite good with this controller. The tag based IO logic was easy to get used to and the functions were not that difficult to find or figure out. The IO cards for this series are open circuit board type rather than a totally enclosed card which I have not encountered before, so care needs to be taken when installing, moving or working with these. For the price, processing power, program memory size so far it has proven to be a good unit. Will be updating the rest of our production equipment to these in the near future.

Selection is a function of application complexity. I watch for the instruction set to evolve to that of Allen-Bradley's Logix, including the ability to create user defined data types.
