Special messages let you monitor and control certain functions of the
DL40 Plus while remaining in Run mode. These messages normally
occupy message numbers 901 to 916. You have the ability to move
special messages to message numbers 1 to 16 or to disable them
using the Onboard Editor or Offline Programming Software.
When operating in Message List run mode, do not add special
messages to the list. Trigger them only as priority messages.
