PAC TECHNOLOGY PAC technology is based on PreprogrammedFunction Blocks Similar to PLC, PAC , to be connected in different architec-tures allowing to design millions of different applications in process control. technology is mainly applied toAnalog Control because it combines Analog and Logic functions at the same time. This > PREPROGRAMMED FUNCTION BLOCKS The Function Blocks are virtual groupings of structured functionsindependently and look like classic structures used long ago with commercial discreet components inside the instrument. The programming is based on virtual connection of blocks...
