Fieldbus interface connector layout
The bus connector layout for DeviceNet
BUS OUT: M12 5-pole socket, A -coded
BUS IN: M12 5-pole plug, A-coded
BUS IN and BUS OUT fieldbus interface connectors are connected inside the SI unit for a daisy-chaning
structure as shown in the circuit below.
If you are concerned about disruption of "downstream" devices whilst replacing SI unit, use a
TM
DeviceNet tap rather than making connections to the BUS OUT connector.
Note
Connect terminating resistors to both ends of the DeviceNet
Be sure to fit a seal cap on any unused connectors.
Proper use of the seal cap enables the enclosure to achieve IP67 specification.
