DeviceNet
The following figure shows the basic connection topology for DeviceNet using a micro-
style connector (the example depicts an ABOX with terminals and cable glands):
• The connection can be made via a multiport or T connector. Observe wiring instruc-
tions compliant with DeviceNet specification 2.0.
• The DeviceNet segment must be terminated using bus terminating resistors at the
first and last physical station to prevent malfunctions in the bus system due to reflec-
tions, etc.
• Use external bus terminating resistors.
NOTES
The example is valid for the following connection boxes:
• ABOX with terminals and cable glands "MTA...-S02.-...-00"
• Hybrid ABOX "MTA...-S12.-...-00" and "MTA...-S22.-...-00"
• HanModular
