The fieldbus and device levels are connected via an I-port.
I-port is a Festo-specific port for the transmission of commu-
nication data (process data, sensor signals, pilot signals) and
supply voltage. The I-port communication protocol is based
on the IO-Link protocol. The electrical and mechanical connec-
tions between the bus node and I-port device are standard-
ised.
