MULTIFUNCTION CONTROLLER

Engineered to simplify the programming operations of the work cycles for the processing machines of all manufacturing fields,NEXUS joins the functional flexibility of the PLC with the absolute novelty of its interface completely programmable by the user bymeans of NEXUS-Wintools, a software developed by ELAP. The storable data structures with indexed access (receipts) allow to fit the configuration of the user interface to the most differentapplication requirements.
