Housing
The AES series bus coupler for PROFINET IO has a 100 Mbit full duplex 2-port switch, so that several
PROFINET IO devices can be connected in series. As a result, the controller can be connected to
either fieldbus connection X7E1 or X7E2. Both fieldbus connections are identical.
Danger caused by incorrectly assembled or damaged cables!
The bus coupler may be damaged.
Only use shielded and tested cables.
Faulty wiring!
Faulty wiring can lead to malfunctions as well as damage to the network.
Comply with the PROFINET IO specifications.
Only a cable that meets the fieldbus specifications as well as the connection speed and
length requirements should be used.
In order to assure both the protection class and the required strain relief, the cable and plug
assembly must be done professionally and in accordance with the assembly instructions.
Never connect the two fieldbus connections X7E1 and X7E2 to the same switch/hub.
Make sure that you do not create a ring topology without a ring master.
