PROFINET IO

What is PROFINET IO?
PROFINET IO is an open transmission system with real-time functionality defined in
accordance with the PROFINET standard. This standard defines a manufacturer-
independent communication, automation and engineering model.
Accessories for wiring the PROFINET components are available in industrial quality.
● PROFINET discards the hierarchical PROFIBUS master/slave concept and deploys a
provider/consumer principle instead. The modules of an I/O device that will be subscribed
to by an IO controller are defined within the engineering phase.
● The quantity framework is extended in accordance with the options offered on
PROFINET IO. Parameter limits are not exceeded during configuration.
● The transmission rate is 100 Mbps.
● The configuration interface for users is generally the same as that on PROFIBUS DP (the
system is configured in STEP 7 > HW CONFIG).
Properties through PROFINET IO
● Integrated switch with 2 ports
● Supported Ethernet services: ping, arp, network diagnostics (SNMP)/MIB-2, LLDP
● Port diagnostics
● IRTtop (Isochronous Real-Time Communication)
● Device replacement without removable medium/programming device
● MRP (Media Redundancy Protocol)
● Supports PROFIenergy
