Appendix E: Event Step Link Reference
E-3
Link Type Description
Position/Pressure Wait for the position on an axis to be
above or below a specified value.
Speed Wait for the speed on an axis to be
above or below a specified value.
Status Bits Wait for one or more status bits on an
axis to be on or off.
E.2 Link Next
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.
E.3 Commanded Axes
As described in Event Control Overview, each event step contains a command and a link section.
The command, by default is issued only to the axis running the event sequence. In this case, the
Commanded Axes field will display "Default."
With RMC CPU firmware dated 19980414 or later, this field can be changed to select one or
more specific axes to receive the command. There are three ways of changing this field:
1. Type directly in the Commanded Axes field. Enter the axes numbers separated by spaces or
commas, and use a hyphen (-) to indicate a range of axes (e.g. the first four axes are indicated by
0-3; the second and fourth axes are indicated by 1,3; etc.).
2. Use the Commanded Axes popup editor. See Using Popup Editors for details on opening the
editor. Once the editor is open, either click Use axis running event sequence, or click Use axes
selected below and check the boxes next to the names of the axes you want to command.
3. With most communication types, you can change the event steps from the programmable
controller. Refer to the section of the communication type you are using for details on changing
event steps. The Commanded Axes field is stored in the most significant byte of the Command
field. See Command/Commanded Axes for a bit map.
