PROFINET Protocol PROFINET uses the IEEE 802.3 (Ethernet) based PROFINET RT protocol for cyclic real-time I/O communication and RPC (Remote Procedure Call) via UDP/IP for acyclic services. Any kind or
Establishing a Connection The connection is established in several steps By means of a DCP identify request, the controller scans the network for a PROFINET Device with the defined station name. The c
PROFINET Diagnosis This chapter describes how the diagnosis mechanisms from PROFINET can be used in CODESYS . The detection and correction of system-related malfunctions (for example, caused by firewa
Troubleshooting This section describes the troubleshooting of technical problems when using the CODESYS PROFINET drivers (Controller and Field Device). In particular, it covers problems that can occur
Alarms In the case of a change to the entries of the diagnosis database, the PROFINET Device sends an alarm to the PROFINET Controller. This immediately signals the coming or going of a malfunction. T
Runtime Configuration (CIFX) For the CIFX version, the corresponding runtime component must be specified in the PROFINET configuration file (*.cfg). In the configuration file, additional settings for
Validity of I/O Data For both incoming and outgoing data, PROFINET devices (Controller and Device) send a status byte in submodule granular form, which marks the I/O data as valid or invalid. From an
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
