Relay Output (Release 3.3 and Prior)

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 Datapoint Browser. 

To control the state of a relay output with the CMS Datapoint Browser, perform the following steps:

1. Open the Datapoint Browser.

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 Name: relay
   3. Block Index: 1 – 2 for relay output (DO) 1 or 2

To set the relay state using the CMS Datapoint Browser, set the relay-val datapoint level value to true or false.

To close the relay, set the level value to true. 

To open the relay, set the level value to false.
