AO Attribute Introduction

WISE provide Analog Output as Voltage output or Current output, each can be applied to different application field. AO attribute setting allows to set up initial output value of the AO channels for controller when is power on. In the logic rule settings, the AO channel value can be used to perform mathematical operations with the value of the other AI/AO Channel, Internal Register or specified value by operators"=", "+=", or "-=",etc.; the result can be included in the THEN/ELSE Action.

AO Attribute Setting
  • WISE-71xx, 790x, 4000
  • WISE-580x

The configuration page is shown as below:

Follow the following steps:

i.

Specify the channel you are going to configure by selecting channel index from the dropdown list of channel field in “Module& Channel” section.

ii.

Input Nickname for each I/O channel, this nickname will be displayed on the “Channel Status” page.

iii.

You can set the initial value of the AO channel in the “Power On Value” field. The hardware device will output this value when is power on. The default initial value is 0.

iv.

Repeat steps i ~ iii. After all AO Channel settings are completed, click “Save” button to save the changes.

For XW-Board:

The XW-Board AO Channel Setting page is shown as follow: (using XW304 as an example)

The settings are as follow:

．

Nickname：For users to define nicknames for each I/O channel, this nickname will be displayed on the “Channel Status” page.

．

Power On Value： You can set the initial value of the AO channel in the “Power On Value” field. WISE-580x will output this value for the AO channel when is power on. The default initial value is 0.

For I-7000 module:

The I-7000 module AO Channel Setting page is shown as follow: (using I-7024 as an example)

The settings are as follow:

．

Nickname：For users to define nicknames for each I/O channel, this nickname will be displayed on the “Channel Status” page.

．

Type：Select the appropriate AO signal output type.
Please note: please use DCON Utility to set up the Power On Value for each AO channel on I-7000 modules.

AO Attribute Rule Setting
．AO Action:
 

Users can modify the AO Channel value in the THEN/ELSE Action statement.

AO Channel Operator Variable Description Execution Type

AO Value of Channel N

 =
+=
-=		 Self-Defined Value The value defined by user. One Time / Repeat
AI Channel Value One of the AI channel value of the module.
AO Channel Value One of the AO channel value of the module.
Internal Register One of the Internal register value of the module.
Operator Description
= Assign the new AO channel value as the value in "Varibale" field.
+= Assign the new AO channel value as the original AO channel value plus the value in "Varibale" field.
-= Assign the new AO channel value as the original AO channel value minus the value in "Varibale" field.

AO Attribute Application Example
Scenario Example Document

Assume a fan is connected to an AO channel on a WISE controller, 10 seconds later after start the controller, it will automatically output 5V to the fan via AO channel to get the fan run.
