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, 72xx, 75xx, 790x

 

The AO attribute setting page is shown as below:

Follow the following steps:

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

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

  3. 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.

  4. Repeat steps 1 ~ 3. 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.

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.

WISE-52xx, 224x

For XV-Board:

The XV-Board AO Channel Setting page is shown as follow: (using XW310 as an example)

The settings are as follow:

  • Nickname: For user to define nicknames for each I/O channel, these nicknames will be displayed on the “Channel Status” and “Rule Setting” pages.
  • Power On Value: You can set the initial value of the AO channel in the “Power On Value” field. The default initial value is 0.
  • Power On Value: You can set the initial value of the AO channel in the “Power On Value” field. The default initial value is 0.

For I-7000/DL DCON module:

The I-7000/DL DCON 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.
  • Description: The Description field provides a space for the user to make a brief description of this module.
  • Address: The address will be the DCON address of this I-7000/DL DCON module, please make sure the address is the same as the settings of the module, if the setting is not accurate, the connection for WISE-52xx/WISE-224x to the I-7000/DL DCON module will be failed.
  • Scan Rate: Input the time interval for WISE-52xx/WISE-224x to periodically retrieve the I/O channel data of this I-7000/DL DCON module, the setting range will be 0 ~ 65535 seconds.
  • Retry Interval: The time interval to wait for WISE-52xx/WISE-224x to repeatedly send command again when WISE-52xx/WISE-224x sends command to the I-7000/DL DCON module and get no response. The unit will be second. The setting range will be 3 ~ 65535 seconds.
  • Type: Select the output signal type of the AO channel from the dropdown list.

Please note: To set up the Power On value of the AO channels on I-7000/DL DCON modules, please use DCON Utility to set the value.

 

AO Attribute Rule Setting

    • AO Condition:

Identify the value of AO channel to be equal to, greater than, less than, equal to or greater than, equal to or less than the “Variable”, if the result matches the evaluation criteria, the Action will be executed.

AO Channel Operator Variable Description Condition Statements
AO Value of Channel N =
>
<

User-Defined Value Using a user-defined value to compare with the AO channel N value. continue to be TRUE when the status matches the criteria
Internal Register Using the internal register value to compare with the AO channel N value.
AI Channel Value Using AI channel values of module to compare with the AO channel N value.
AO Channel Value Using AO channel values of module to compare with the AO channel N value.
Input Register Value Using input register values of module to compare with the AO channel N value.
Holding Register Value Using holding register values of module to compare with the AO channel N value.

Only WISE-52xx/WISE-224x supports to use AO channel status as IF conditions.

    • 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 =
+=
-=
User-Defined Value The value defined by user. One Time / Repeat
Internal Register One of the Internal register value of the module.
AI Channel Value One of the AI channel value of the module.
AO Channel Value One of the AO channel value of the module.
Input Register Value One of the Input Register value of the module.
Holding Register Value One of the Holding 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.
