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. In other news from the company, it has made touchscreens the standard interface on every NovaWheel model of resin dryer.
The Novatec FXS PLCs, Siemens-based and with color touch screens, can handle polymer-conveying systems with up to 20 pumps and 120 stations. The base panel controls up to 5 vacuum pumps and 32 material receivers with proportioning capability, and 25 purge valves. An icon-driven graphic display makes for an easy-to-learn user interface.
Ethernet connection capability permits full control access from any remote personal computer. The PLC is also supported by ProfiNet communications for adding more components remotely. Expansion is accomplished via FlexXpand FXMS modules that connect to the main control via ProfiNet communications network. Modules can be positioned to minimize wiring to system components. The modules control additional receivers, pumps, purge valves, or material-selection stations when automatic proofing is desired for selection validation....
