12. From the Edit Device Parameters window of the Communications Unit,
click Reset.
The Communications Unit and all the I/O Units connected to the Commu-
nications Unit will be reset, and the specified parameters (for example, for
output range) will be enabled.
Note Even if Reset is not clicked and the power supply for the Communi-
cations Unit is switched OFF and ON again, the settings will be en-
abled.
Adjusting Offset and Gain Use the following procedure to adjust the offset and gain settings. The
DeviceNet and the MULTIPLE I/O TERMINAL must be connected first.
Note 1. The offset and gain can be adjusted only with a Configurator Ver. 1.20 or
later.
2. With the earlier model GT1-DA04MX Analog Output Unit, the offset and
gain cannot be adjusted, even with a Configurator Ver. 1.20 or later. Check
the label on the front on the Unit for whether the offset and gain can be ad-
justed. Offset and gain can be adjusted only if the letter B appears on the
label as shown below.
Offset Adjustment
Offset adjustment is used to adjust outputs so that when the value corre-
sponding to 0% in the output range is written, it is converted accurately to out-
put 0%. Offset adjustment is used when output voltage and output current
differ from the actual value of 0% due to the features of the Unit or the method
of connection being used.
