Fieldbus Connection
Description
The splitter box can either be in the middle of the chain connection or at line end.
The fieldbus is connected via 5-pin M12 connectors (B-coding).
Pin Assignment
The following diagram shows a front view of the bus connectors (B-coding)
NOTE: It is preferable to connect the shielding to the connector housing. If this is not
possible, the connection can also be made using pin 5. These two possibilities can
also be combined.
