Special Messages
This chapter describes the use of Special Messages with both the Remote I/O
and Parallel Port versions of the DL40.
Triggering Special Messages gives you the ability to monitor and control
certain functions of the DL40 while remaining in the 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.
