Relay Output

THE DATAPOINTS WIDGET IS AVAILABLE WITH SMARTSERVER 2.5 AND HIGHER. FOR SMARTSERVER 3.3 AND PRIOR RELEASES, THIS WIDGET IS CALLED THE DATAPOINT BROWSER WIDGET.

You can control the state of the two IOX relay outputs. You can control a relay output state by creating a connection to another datapoint with a connection file, by updating the datapoint from a Sequencing widget data flow or web flow, or by writing to the relay output block using the CMS Datapoints widget. 

To control the state of a relay output with the CMS Datapoints widget, perform the following steps:

1. Open the Datapoints widget. Click the Expand button (  ). 
   

   
   
   

2. Set the filters to find and select the IOX digital output block:
   1. Device: iox[1-n] – the first installed IOX will be iox1, the second will be iox2, etc.
   2. Block: relay

   3. Block Index: 1 – 2 for relay output (DO) 1 or 2
      
      With IOX 2.3 and higher, a SNVT_switch datapoint can be used to control the relay. 
      
      
      
      

3. Click the Action button () for the relay-val datapoint and then select the Edit Value action.
   
   
   
   The Edit Value view appears.
   
   
   
   

4. Set the relay-val datapoint to 0 → OPEN or 1 → CLOSE. For IOX releases prior to 2.3, the level value is 0 → false / 1 → true.

   
   
   • To close the relay, set to 0 → OPEN. 
   • To open the relay, set to 1 → CLOSE.
     
     
5. Click SAVE to store your configuration changes.
