Abbreviation/term Significance
EDS Electronic Data Sheets contain product-specific data, e.g. the bus node
characteristics
see also “DCF” Appendix A.2
EDS library Manages the characteristics of the various fieldbus/network participants
Fail state Bus node function, also referred to as “fail safe” function; defines the
state assumed by outputs or valves following network or communication
errors, activates for example a reset of the outputs - or alternatively holds
the last state
I-port I-port is a Festo-specific interface for transmitting communication data
(process data, sensor signals, pilot signals) and supply voltages. The
I-port communication protocol is based on the IO link protocol. The elec-
trical and mechanical link between bus nodes and I-port device is stand-
ardised.
