Significance
Electronic Data Sheets contain product-specific data, e.g. the bus node
characteristics see also "DCF"
Manages the characteristics of the various fieldbus/network participants
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 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.
Makes all important fieldbus/network participant parameters accessible
in a standardised manner
Open Device Vendor Association, DeviceNet umbrella organisation
Programmable logic controller, also referred to as system controller or
controller for short
Configuration, parameterisation, commissioning and diagnostics software
for DeviceNet from Rockwell Automation/Allen-Bradley
