Question
What is the difference between methods to
use a terminating resistor attached to the T-branch Tap or a Terminal
Block style terminating resistor of the DeviceNet?
Answer
It differs by whether the T-branch Tap "DCN1-1C" and/or "DCN1-3C" is
located within 6m or more than 6m far from a node of the main line.
If it is located within 6m from a node of the main line, a supplied
terminating resistor can be attached to the T-branch Tap.
If it is located more than 6m far from a node of the main line, a
terminating resistor must be attached to the end of the node.
In this case, the T-branch Tap fitted with a terminating resistor or the
Terminal Block style terminating resistor DRST-1 must be connected. The
maximum cable length between the node and the terminating resistor is 1m.
