Storing Steps
Steps are stored in the motion controller’s memory. This step table can be saved in the
motion controller’s FLASH using the Update FLASH command . However, in some
applications this information should be stored in the Programmable Controller so that it
can be downloaded to the motion controller on initialization. Refer to the Event Step
Transfer for details on storing the steps.
Changing Event Steps
Refer to Editing the Event Step Table for details on using the Event Step editor.
Basic Event Step Flow
After a valid event step sequence is loaded into the motion controller, event control can
be used. This section describes the basic flow:
To start a sequence of events, do the following:
• Issue a Start Event command to trigger an event from the monitor program or
Programmable Controller.
A sequence of events will stop when one of the following occurs:
• A Quit Events command has been issued from the monitor program or Programmable
Controller.
• A step is executed which has a Link Type of 0.
• A Halt or Disable Drive Output command will stop the event sequence as well.
• Another Start Event command will stop the current sequence and start the new one.
The following additional details should also be kept in mind:
• The Mode, Accel, Decel, Speed and/or Command Value fields need not be filled out
if the command does not use them.
• The command field can be left blank in a step if only the link type is being used. You
can chain steps together to make a sequence wait for multiple conditions to all be
true.
