DO Attribute Introduction

In additional to Digital Output ON & OFF basic operation, WISE DO Attribute setting allows to set up detail configuration of DO channel, including Power On value, Pulse Output and DO Counter.

DO 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 specify the initial status to be “ON” or to be “OFF” when the hardware device is power on. Select the value from the dropdown list of “Power On Value” field. The default value is “OFF”.

vi.

You can set the trigger criteria for triggering the counter to count. There are three criteria: HI to LOW, LOW to HI and Status Change. This field cannot be “Disable” if you want to use the counter function of this channel. You can also specify the initial value of the counter in the “Initial Value” field. This counter will start counting from the initial count value. The default initial value is 0 and the range of initial value is between 0 and 65535.

v.

If you check the Enable pulse output checkbox, it will allow this DO channel to perform pulse output. In Pulse Output mode, the selected DO channel will generate a square wave according to specified parameters (Pulse High and Pulse Low). Pulse High and Pulse Low are required and has to be entered in multiples of 10ms. Pulse High indicates the “ON” time duration and Pulse Low indicates the “OFF” time duration in a periodic Pulse cycle. The range of pulse high and pulse low are between 1 and 65535.

vi.

Repeat steps i ~ v. After all DO channel settings are completed, click “Save” button to save the changes.

For XW-Board:

The XW-Board DO Channel Setting page is shown as follow: (using XW107 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 specify the initial status to be “ON” or to be “OFF” when the WISE-580x is power on. Select the value from the dropdown list of “Power On Value” field. The default value is “OFF”.

．

Pulse Output: If you check the Enable pulse output checkbox, it will allow this DO channel to perform pulse output and form a periodic pulse cycle. In Pulse Output mode, the selected DO channel will generate a square wave according to specified parameters (Pulse High and Pulse Low). Pulse High and Pulse Low are required and has to be entered in multiples of 10ms. Pulse High indicates the “ON” time duration and Pulse Low indicates the “OFF” time duration in a periodic Pulse cycle. The range of pulse high and pulse low are between 1 and 65535.

For I-7000 module:

The I-7000 module DO Channel Setting page is shown as follow: (using I-7060 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.

Please note: To setup the Power On Value on DO channel for each I-7000 module, please use the DCON Utility to setup the value.

DO Attribute Rule Setting
．DO Action:
 

Change the DO Channel status to specified status. The status can be set as "OFF", "ON" or "Pulse Output".

DO Channel Action Description Execution Type
DO Channel N Status ON Change the DO Channel status to be ON One Time / Repeat
OFF Change the DO Channel status to be OFF
Pulse Output Change the DO Channel status to be Pulse Output
‧The DO channels on I-7000 modules do not provide Pulse Output function with WISE-580x.
．DO Counter Condition:
 

Identify the value of DO Counter to be equal to, greater than, less than, equal to or greater than, equal to or less than the specified value, if the result matches the evaluation criteria, the Action will be executed. The action also can be executed when there is a change to the value of the DO Counter.

DO Counter Operator Value Description Condition Statements
DO Counter
Value of Channel N		 = Value Identify if the value of DO Counter is equal to the specified value. Continue to be TRUE when the status matches the criteria
> Identify if the value of DO Counter is greater than the specified value.
< Identify if the value of DO Counter is less than the specified value.
>= Identify if the value of DO Counter is equal to or greater than the specified value.
<= Identify if the value of DO Counter is equal to or less than the specified value.
Change - Identify if there is a change to the value of DO Counter Turn to be TRUE only once when there is a change
‧The DO channels do not provide Counter function with WISE-580x.
．DO Counter Action:
 

When the condition is TRUE, reset the DO Counter value.

DO Counter Action Description Execution Type
DO Counter Value of Channel N Reset Reset DO Counter value One Time
‧The DO channels do not provide Counter function with WISE-580x.

DO Attribute Application Example
  • WISE-71xx, 790x, 4000
  • WISE-580x
Scenario Example Document

Assume a warning light is connected to the DO channel 0 on a WISE controller, the DO0 keeps on sending Digital Pulse Output signals so that the warning light will be triggered and keeps on flashing. At the same time, the DO0 Counter will keep on counting the frequency of the Pulse, and when the flashing frequency reaches a certain amount( in this example, 5000 times), the warning light will stop flashing.

Scenario Example Document

Assume in a product line terminal is equipped with a sensor and a warning light that are connected respectively to the DI channel 0 and DO channel 0 on a WISE-5800 controller (with a XW-Board XW107), when a finished product passes the sensor, the sensor will send out an “ON” signal to the DI channel 0 of the XW107. When the amount of the finished product reached 10, the warning light will start to flash so that the related personnel will be able to perform further process.
