KUHNKE Automation 4 System Description 4.1 Overview Description of functionality The 9-channel thermo-controller is a power controller with the ability to actu- ate ohmic consumers. Ohmic consumers are normally contact heaters or IR radiators. Load voltages can be fed through a bus bar. Separate fuses are thus un- necessary which minimises the amount of space and time needed for instal- lation. Super-fast blow-out fuses in the thermo-controller protect both, actuated outputs and antiphase. Consumers can thus be directly connected without any need for separate fusing. Intelligent soft start by phase-fired controller reduces the inrush load on the mains when energising the unit.
EtherCAT ® 1 fieldbus interface Ethernet Control Automation Technology EtherCAT® is the most powerful Ethernet-based fieldbus system currently available on the market. EtherCAT® puts up the top speed mark, and its flexible topology and simple configuration make it the perfect means of con- trolling extremely fast processes. To give you a clue: 1000 I/Os can be ad- dressed in 30 μs. Because of its high performance, the simple wiring and its open protocol support, EtherCAT® is often used as a fast motion control and I/O bus driven by an industrial PC or in conjunction with control technology on a smaller scale. EtherCAT® moves beyond the limits of conventional fieldbus systems.
Its interconnections between the controller at one end and both the I/O modules and drives at the other are as fast as those of a backplane bus. EtherCAT® controllers thus nearly act like centralised control systems, over- coming the issue of bus transfer times that conventional fieldbus systems are burdened with. Integrated functions • Extensive diagnostic options provide quick information about the thermo-controller and the load users need to efficiently locate problems. - Load failure - State of fuse - Power supply failure • A software function module for CoDeSys controller programs helps us- ers integrate the controller into the control system.
• Parameter setup and actuation data is exchanged via an EtherCAT® fieldbus which supports networks of hundreds of thermo-controllers. • LEDs for optional output status indication help locating faults immedi- ately at the switching cabinet 1 EtherCAT® is a registered trademark and patented technology, licenced by Beckhoff Automation GmbH, Germany.
