Note
Functional earthing
IE/AS-INTERFACE LINK PN IO has a connector for functional earthing. This
connector is required if the integrated ground fault monitoring is used. It should be
connected to the PE conductor with as little resistance as possible.
LAN Connectors (PROFINET IO, PC with WBM)
As connectors for PROFINET and a PC (or network) there are two RJ-45 jacks
(recommendation: 90° FC connector).
One LAN connector is intended for the PROFINET system, the second LAN
connector of the IE/AS-i LINK is used, for example, for configuration with Web
Based Management and for diagnostics. The two LAN connectors have equal
status.
The IE/AS-i LINK supports autocrossing, in other words, both crossover and
straight-through cables can be used.
Pin Assignment of the LAN Connector
