Web API WEB API

Runs one command on a Web API Link.

Rung rise, through Web API, to Result and status tags in the project.Rung riseWeb APIResult and status tags

How it works

When the rung turns on, it sends the command once. Holding the rung on does not send again. To send again, the rung must turn off, then on, after Busy has cleared.

In practice

Place a ladder step that names one imported operation on one Web API Connection.

Configuration

  • Drop Web API, pick the Connection, pick the imported operation.

Limits and status

  • A missing pin leaves the instruction incomplete.
  • A stale pin fails closed and never silently rematches another revision or Connection.

Operands

Choose the Link and its command in the instruction. Map parameters and result tags there.

Common mistakes

  • Running it before the Link is set upChoose the Link and its command in the instruction first. Without them it does not run.
