Opto 22 Nodes

Read and write Opto 22 points from a pipeline, using the functions saved on an Opto 22 connection.

Needs

Saved Opto 22 connection

Output

Typed values by point name

Limits

Uncertain writes are not repeated

Parameters Tab

Select a saved Opto 22 connection and function. Configure addresses and values in the connection guide. Writes require current inputs; uncertain writes are not automatically repeated.

Settings Tab

The Settings tab holds the node's Description, Timeout (seconds), Retry on Timeout, Retry on Fail and On Error (Pipeline Default, Stop Pipeline or Continue Execution). All execution settings default to the pipeline-level values.

Opto 22 Read Node

Node type: connected.opto22.read. Runs opto22.read.

{"result":{"count":2,"values":{"pump":true,"level":512},"quality":"good","totalDataPoints":2,"totalReads":1}}

Field	Meaning
result.count	Number of decoded points
result.values	Typed values by point name; LINT values are decimal strings
result.quality	good; a failed read fails the node
result.totalDataPoints	Requested point count
result.totalReads	Read requests made

Opto 22 Write Node

Node type: connected.opto22.write. Runs opto22.write.

{"result":{"address":"SPB7","dataType":"BIT","value":true}}

Field	Meaning
result.address	Address written
result.dataType	Type of the address
