The ZX20 controller from Zander was designed to eliminate all cycle times. For this purpose, the user program is burned into an FPGA (Field Programmable Gate Array). This means that the program no longer runs; instead, complete parallel processing takes place. The complete user program is converted into hardware, so to speak. The programmer creates his program in the PLC language ST (Structured Text) and loads it into the controller as in a conventional PLC. According to the manufacturer, the cycle time of the ZX20 is always the same and constant, namely zero. Communication with other controllers or PCs takes place via Ethernet at 10 or 100 MBit/s. The integrated Zandernet protocol supports networking here. Communication is possible with or without third-party protocols in the network. The user program is also transferred to the controller via the Ethernet interface. The analog processing in the controller also has no cycle time. This also makes it possible to record rapidly changing measured values and process them logically at the same time.
