From: Sven Van Asbroeck <sven...@arcx.com> The Anybus-S PROFINET IRT communication module provides instant integration to any Ethernet based LAN via SMTP, FTP, HTTP as well as PROFINET and Modbus-TCP. Additional protocols can be implemented on top of TCP/IP or UDP using the transparent socket interface.
Official documentation: https://www.anybus.com/docs/librariesprovider7/default-document-library /manuals-design-guides/hms-hmsi-168-52.pdf This implementation is an Anybus-S client driver, designed to be instantiated by the Anybus-S bus driver when it discovers the Profinet card. If loaded successfully, the driver creates a /dev/profinet%d devnode, and a /sys/class/misc/profinet%d sysfs subdir: - the card can be configured with a single, atomic ioctl on the devnode; - the card's internal dpram is accessed by calling read/write/seek on the devnode. - the card's "fieldbus specific area" properties can be accessed via the sysfs dir.
