ZX21TC high-speed-controller with EtherCAT

The new high speed controller ZX21TC also does not have any cycle time and thus, always ensures fastest possible - and even more important - constantly fast processes. How is this possible?

Often single high-speed requirements needs to be processed in integrated control systems.

E.g. recording of measurement data or pace critical activities like counting, sorting or printing of products. In this case ZX21 bus variants are the right choice. With the integrated EtherCAT interface (ZX21TC) single control systems can be integrated in higher systems.


This means:

  • Direct, simple integration in higher control systems
  • No additional hardware is necessary
  • High-speed data transfer
