CombiBOX Analog Cbox A

The all-rounder CombiBOX A is basically designed for three applications:

1. Cbox A as a passive BUS terminal

Cbox A is a platform for high-speed automation-Systems. Based on an ultra-fast BUS cycle time of 50µs provides the fieldbus terminal with an EtherCAT-Slave-Interface analog and digital Inputs / Outputs. On the contrary to a  standard PLC - which operates at a cycle time of 1ms – realizes the Cbox A a BUS cycle time of 50µs, thus a  20 times faster and therefore a 20 times more precise evaluation of the process as conventional PLC systems. Real time software solutions are realized e.g. with the Soft-PLC TwinCAT.

2. Cbox A as an active PLC-Sub-System

Cbox A suits optimal as a high-speed PLC-Sub-system, to collect, evaluate, actuate and control stand-alone analog and digital process data and provides the process parameters additionally via  an EtherCAT-Interface to a host system. Due to the high-speed internal processing of the  I/O-Signals via CPU <50µs and FPGA <1µs are cycle times realized which are only a fraction of the BUS cycle.

3. Cbox A as an Embedded System

The Cbox A is also a stand-alone system for individual test- / control-applications available. Programming with C- programs for the ARM-Controller or with VHDL for the FPGA. Development Kits for individual applications are available.
