1,2,3...
The DeviceNet Communications Unit's baud rate is automatically adjusted to
match the Master's baud rate. The Communications baud rate is set and
saved after the power is turned ON and communications with the Master are
established. The baud rate setting is retained until the next time that the
power is turned ON.
If the Master's baud rate has been changed, the DeviceNet Communications
Unit must be turned OFF and then ON again to change its baud rate.
The present, bottom, and peak values of the Network power voltage can be
recorded in the DeviceNet Communications Unit. A monitor voltage level can
be set with the Configurator and recorded in the DeviceNet Communications
Unit. The Network Power Voltage Error Flag in the Status Area will be turned
ON when the voltage drops below the set monitor value. The current, mini-
mum, and maximum values of the Network power voltage, and the Network
Power Voltage Error Flag can be read from the Configurator.
1. The communications power voltage of the actual DeviceNet is 11 V mini-
mum, so if the communications power voltage drops below 11 V, the oper-
ation for reading the measurement values using the Configurator may not
function properly.
2. The maximum and minimum Network power voltages are cleared when the
Network power is turned OFF.
The method used to set values from the DeviceNet Configurator (Ver. 2.43 or
later) is described here.
1. Turn ON the DeviceNet Communications Unit's power supply.
2. From the Main Window, open the Network Configuration Window and dou-
ble-click or click the right mouse button over the icon of the DeviceNet
Communications Unit to be set. Select Parameter and Edit to display the
Edit Device Parameters Window.
From the Maintenance Mode Window, click the right mouse button over the
icon of the DeviceNet Communications Unit to be set. Select Parameter
and Edit to display the Edit Device Parameters Window.
