Product Watch: Novatec introduces PLC control system for centralized conveying systems, makes touchscreen standard


Plastics auxiliary equipment manufacturer Novatec (Baltimore, MD) has begun marketing its new Novatec FXS (FlexXpand) programmable logic controls (PLC) to help processors keep track of plant-wide operations.
