Checking Maintenance Information

Note The allowable current of Thin Cables with shielded connectors is 3 A, and for
Thick Cables the allowable current is 8 A.
Multi-drop wiring cannot be used for round communications connectors. Use
T-branch wiring and T-branch Taps to connect cables with shielded connectors
on both ends.
The rated current capacity of the T-branch Connector's communications
power supply pin is 3 A.
A cable with a connector (socket) on one end can be used to connect to a
standard DCN1-@C T-branch Tap. A cable with a connector (socket) on one
end can also be used to connect to the communications power supply from a
T-branch Connector.

Note Tighten the connector by hand to a torque of 0.39 to 0.49 N·m. If the connec-
tor is not tightened sufficiently, it will not provide the expected degree of pro-
tection and may become loose due to vibration.
Do not use pliers or other tools to tighten the connectors, because these tools
may damage the connectors.
This section describes the Maintenance Information Window, which can be
used to check the status of Environment-resistive Slaves. The Monitor Device
Window can be used to check the same Slave status information, but the
examples in this section uses the Maintenance Information Window. Refer to
4-1-2 Maintenance Mode Window for details on the differences between the
Maintenance Information Window and the Monitor Device Window.
From the DeviceNet Configurator's Main Window, click the right mouse button
and select Maintenance Information. (From the Maintenance Mode Window,
double-click the icon of the desired Slave.)
