Dynamic References

Jump to Section

Inputs can reference other Inputs or Instances in their configuration.

An example of this is a SQL input that references a machineID from an OPC UA input to pull maintenance data for the machine. The syntax for referencing another input is as follows.

sql

SELECT * FROM machineTable WHERE machineID={{Connection.opc.machineIDTag}}

When this input is read, the referenced input is read first and the result is inserted into the query. If the referenced input read fails, the input read will also fail.

Dynamic references are supported on any text based input field.
