Controller Redundancy To increase the availability of the system, you can use a second controller with a redundant PROFINET controller combined with CODESYS Redundancy . CODESYS Redundancy acts as a "

Media Redundancy (MRP) Media redundancy (based on MRP – Media Redundancy Protocol) is a function for increasing the system availability by means of redundant communication paths. Standard Ethernet all

Diagnosis in the Application Device Function Block For each PROFINET Device in the device tree, a function block is created that provides basic information about the connection or configuration status

Diagnosis in the User Interface Device tree In online mode, the device tree allows for an exact pinpointing of a pending diagnosis. The error flag (red symbol) indicates a hard error, such as an incor

Runtime Configuration For communication with the PROFINET RT protocol, the PROFINET IEC stacks use a special runtime interface (SysEthernet) that allows the transmission of RAW Ethernet frames. This r

Firewall and Package Filter The PROFINET stacks do not use the configured Ethernet adapters of the PLC exclusively. The PROFINET protocols run parallel with the network protocols (for example, UDP), a

CODESYS Communication Insofar as multiple Ethernet adapters exist on the controller, it is generally recommended to separate the CODESYS communication (project download, monitoring, etc.) and the fiel

Configuring the PROFINET Controller Tip We recommend that you configure a static IP address in the operating system for the used Ethernet adapter. Windows The following configuration steps are necessa

Configuring a PROFINET Device Linux The following configuration steps are necessary in Linux for a standard-compliant behavior (here as an example for Debian/Raspi) : In the CODESYS project, disable t
