Reviews for CPUs (Remote & Expansion)

This processor is easily as or powerful than any processor available. I have had some trouble adjusting to the need to use tag-based programming, but that is me: I'm old-school. I just completed a three-processor upgrade to a system of two drop-bottom ovens and a Quench Management system. They share data over an Ethernet link. These systems were originally SLC504 CPUs. I translated the programs and the Panelmate touchscreens. The systems are working like new. The PID is very easy to use.

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.
