The Link Next field contains the number of the next step that will execute when the condition of the Link Type and Value are met.
The Link Next field can point to any step (from 0 to 255). When a chain of steps is finished the last step should have a Link Next of 0 to indicate so. If a never-ending loop is required, the last step will have a Link Next value of a step earlier in the chain.
When the Link Next field is read or written through PROFIBUS-DP Compact Mode and DI/O Command Mode, it is combined with the Link Type field. See the Link Type/Next field for details on how they are combined, and the Event Step Edit and Event Step Transfer command topics for details on changing these fields from the master controller.
Tip: When editing the steps, you can press CTRL+G to cause the cursor to jump to the step indicated by the Link Next field. This allows the user to view the steps in a step sequence.
