Hello Tech-Talk,
Is it possible to process Linux system file values as PV records ? For example, we are looking to add MAC address and IP address of the IOC server as PVs.
A simple way to access the IOC server MAC address is “$ cat /sys/class/net/eth0/address” and “$ hostname -I” to access the IP address.
Is there a driver for accessing Linux system values ? Any examples for its usage ?
Thank you,
SK
