10-4 Using the DL5 Parallel Port to Replace Pilot Lights
Priority Mode In the priority mode of operation you can only specify an ON state message
for each input. If several inputs are ON, only the highest priority message
will be displayed. The following table lists the message numbers that are
assigned to each of the sixteen inputs.
If programmed, message #17 is displayed if no data lines are ON.
Notice that each of the sixteen data lines listed in the table above only has
an ON message number assigned. You do not have to program a message
for each of the inputs; if an input does not have a message programmed, the
DL5 will ignore the input. Each input has an assigned priority level. Data
line D0 has priority over data line D1, data line D1 has priority over data
line D2, data line D3 has priority over data line D4, etc. The DL5 displays
the message number that corresponds to the highest priority data line. For
example: If data lines D1, D4, and D7 are in an ON condition, the DL5 will
display message #2 (message #2 is the message assigned to data line D1).
Message #2 will continue to be repeated for as long as data line D1 remains
in an ON state; unless data line D0 changes to an ON state. If data line D0
changes to an ON state, it overrides data line D1 because data line D0 has a
higher priority. The DL5 then displays message #1 (message #1 is the
message assigned to data line D0). If only one input is ON and that input
goes OFF, the display will automatically clear.
In addition to the sixteen messages associated with data lines D0 through
D15, there is a message #17. Message #17 is only displayed when none of
the data lines is in an ON condition.
Data Line No. ON Message No. OFF Message No.
