Analog Output Units
Section 5-2
Note
1.
When setting the output range or output for communications errors using
a DeviceNet Configurator, use version 1.11 or later. (If pin 10 is ON, and a
setting is made using the Configurator, the output ranges will all be 0 to 5 V
and the output for communications errors setting will be set to clear to min-
imum.)
2.
Make sure the I/O Unit power supplies (including the I/O Unit interface
power supply) are OFF when setting the DIP switch.
3.
With an Analog Output Unit, output for communications errors is enabled
using the switch on the Analog Output Unit. It does not depend on the
Communications Unit “hold/clear communications error” setting.
Output Range Settings
As shown in the following table, the DIP switch output range settings are for
two outputs each.
Note If output range setting is performed using the Configurator (version 1.11 or
later), it is possible to make the setting for each point.
Output Setting for Communications Errors
When clear to minimum, clear to maximum, or clear to 0 V is set using DIP
switch pins 8 and 9 and a communications error occurs, the outputs shown in
the following table will be produced according to the output range.
