In connection with the gateway, the CRFX modules act as a data acquisition subsystem in the sense of an EtherCAT slave, without operating in the network of a complete CRONOS data logger. The individual modules are interconnected via the CRFX system bus. This CRONOS system bus is based on the "EtherCAT standard", uses network hardware and is spatially distributable via network cables (Power-over-EtherCAT). The protocol of the CRONOS system bus differs from the "EtherCAT Standard". It is not compatible with EtherCAT 3rd party systems.
i.e. the CRFX modules cannot be operated in such an environment. The ECAT gateway establishes this connection, forming a single EtherCAT slave station.
The ECAT slave subsystem is configured once using imc STUDIO via EtherNET. Afterwards and during active operation this access is no longer necessary.
