Operation
Navigating to the A/O Operation screen sets the mode to A/O Manual and all the outputs of 32
A/O channels become 4 mA. On the A/O Operation screen, setting commands are available for
any of the up to 32 A/O channels. Navigating to other screens cancels the A/O Manual mode, and
according to the settings, outputs are made from each A/O channel.
To set the output value of an AO, select the A/O number with the cursor, enter the set value and
press the Set/Ent key. Note that this operation must be done in Manual status and in Stop mode.
