Novatec (www.novatec.com) has launched its latest Novatec FXS (FlexXpand) programmable logic controls (PLC), which helps processors monitor plant-wide operations.

Featuring color touch screen control panels, this Siemens-based PLC can support polymer-conveying systems with up to 120 stations and 20 pumps. Its base panel can control up to 25 purge valves, 32 material receivers with proportioning capability and five vacuum pumps, while its icon-driven graphic display offers an easy-to-learn user interface.

With Ethernet connection capability, the PLC can be controlled from any remote personal computer. It is also designed with Profinet communications to allow the PLC to remotely add more components. Expansion is achieved through FlexXpand FXMS modules that automatically connect to the main control through Profinet communications network. The modules, which control additional pumps, receivers, material-selection stations and purge valves, can be arranged in such a way to minimize wiring to system components.

Every FXS control features a three-port Ethernet connection for added FXS modules or remote or local human-machine interface (HMI) modules. Expansion requires no additional programming, since all modules are automatically recognized by the FXS control.

Moreover, both visual and audible parameters are integrated on the control face. With assignable levels of security, various changes to operating parameters can be easily made. Likewise, the Ethernet capability of FlexXpand allows the advanced, intuitive interface to monitor as well as control other Novatec ColorNet-compatible HMI’s integrated on the local network.
