consumed, quantities of finished products and quantities of materials that are not within specifica- tion. The CPCC stores all this production and process data in an integrated database and forwards it to a long-term archive. Communication from the CPCC to Coperion’s


production lines uses the OPC UA (Unified Archi- tecture) communication protocol, so third-party systems can also connect to it.


Innovative data KraussMaffei Berstorff offers what it says are two innovative data acquisition solutions as options on its new ZE BluePower twin-screw extruders. “This enables perfect integration of advanced com- pounding equipment with industry 4.0 technolo- gies,” it says. The first is designed to synchronously collect all production data from a compounding line. The company says it is composed of “perfectly tuned” hardware and software components for acquisition, recording, evaluation and further processing of all process and measured values. The modular system is easy to configure,


KraussMaffei claims. As such, it can be adapted to a wide range of different applications and scaled in size. It is also suited for interface-independent operation, which means that any interface can be integrated into an overall system that collects and visualises the desired process data. Pressure, temperature, speed and volume flow values of all upstream and downstream components – metering systems, melt filters, melt pumps and pelletising systems, and so on – as well as the extruder parameters, are all combined in a single system. The second development from the company


uses colour measurement to instantly detect metering errors, in the process reducing produc- tion scrap and enhancing line efficiency. Light is projected into the melt, reflected and then detect- ed by a high-resolution glass fibre sensor. Data on colour and brightness is compared with a previ- ously defined setpoint and the system is integrated into the overall line control. Al Bailey, Entek’s East Coast Controls Manager in the US, explains how his company de- signs systems to make its extruders compatible with Industry 4.0 in plant compounding operations. “Entek has eight control engineers on staff and four controls engineers dedicated to the extrusion business. This allows for customisation of extruders to work as a part of a line instead of just stand- alone. All of our major components – PLCs, HMIs, VFDs, etc – communicate with each other through
