28.2 COMMERCIAL CONTROLLERS


At the time of writing Allen Bradley did not offer any Fuzzy Logic systems for their PLCs. But, other vendors such as Omron offer commercial controllers. Their controller has 8 inputs and 2 outputs. It will accept up to 128 rules that operate on sets defined with polygons with up to 7 points.

It is also possible to implement a fuzzy logic controller manually, possible in structured text.
