MURRELEKTRONIK, represented in Australia by Sick , has released the Cube67 field-bus coupler with Ethernet interface. It provides transparency between the layers of automation as well as simple, worldwide availability of process and diagnosis data.
Starting from a bus coupler, the I/O layer is distributed right into the machine, independent of the controls, connected by one hybrid cable for power and communications. The compact, robust construction of the encapsulated Cube67 modules allows them to be used close the process. This results in the shortest possible I/O cables to the sensors and actuators.
The bus coupler makes the connection to the field bus. The entire machine installation is independent of the field-bus system used and can be implemented as a universal standard for all machine variants with different controls. This creates a potential for cost savings because separate engineering, documentation and system skills unnecessary.
Digital, analogue and serial signals, temperature registration, counters, and valve-island, drive and operating panel couplings are available.
Multifunctional I/Os, with the digital channels freely programmable as input, output, or diagnosis input, give maximum flexibility. Separate modules for inputs and outputs are no longer needed. The number of variants is minimised, storage costs are reduced, and modifications to the configuration, which may become necessary through system restructuring, are no trouble.
Each machine variant or optional enhancement requires an individual hardware configuration, and thus a separate software version. With Integrated Machine Variant Management (IMVM), the potential full enhancement level is configured virtually. In the real machine, the system automatically adapts to the actual hardware structure. Elaborate software tailoring and administration for each type of machine are no longer necessary. The diversity of the software is reduced to one version per series of machine. Optional upgrading is implemented at the touch of a button.
