Production processes are getting faster and faster. There are many examples: Injection moulding machines for plastic products, automatic packaging and cutting machines, labelling systems, filling devices for the food industry and many more.
As a result, high demands are put on the control system. Here, the challenge is not the absolute reaction time, but rather ensuring exactly reproducible switching points at different machine speeds.
Because of varying cycle times, it is often very difficult for conventional PLC controllers to meet these demands. ZANDER high-speed PLC controller use programmable logic instead of a micro-controller. An FPGA chip takes over all the functions in absolute real-time. The cycle time is 0.000 s!
Because of this no cyclic program is executed - all programs take place in a parallel manner in real-time and that too, several times faster than in a PLC.
And it must be emphasized that there are no deviations in the reaction time.
The controllers operate in a fault-tolerant manner. During a spaceflight experiment, the SPEEDY technology in research satellites has been used successfully and the operational reliability has been confirmed.

For all ZX09 the programming is done via the Ethernet interface; network applications are easily and quickly realized. Of course, you can programm the ZX09 as easily as you are used to in a PLC - with Structured Text (ST) according to IEC 61131-3.
Also for all ZX20 the programming is done via the Ethernet interface; network applications are easily and quickly realized. Of course, you can programm the ZX20 as easily as you are used to in a PLC - with Structured Text (ST) according to IEC 61131-3.
SPEEDY processes your programme internally in an absolutely parallel manner in real-time, without cycle time.
