DM words m+1 through m+11
Outputs #0 though #2 turn ON and OFF according to the counter values set in
DM words m+1 through m+10. The only exception is that output #0 turns ON at
the beginning of the countdown. The diagram below illustrates this situation.
Each of the counter values must be set between 0 and 8,388,607.
The ON time sets the length of time that outputs #4 through #7 remain ON after
completion of the countdown when they are designated in the relevant output
pattern. The setting value must either be between 0 and 99.99 (decimal not in-
put) or it must be ”FFFF”, in which case the designated outputs will remain ON
until the start signal is turned ON again.

IR Area Settings
The IR area contains commands used to operate the Counter Unit and flags
used to monitor its operation. Both of those are used in programming the desired
counter operations.
START Command
Word n, bit 00
The countdown begins on the rising edge of the START command bit according
to parameters from DM area. Note that the countdown will begin with preset #0
unless CHANGE PRESET is ON to designate the number of another preset.
The START command is effective only when pin 4 on the back-panel DIP switch
is turned OFF. If pin 4 is ON, control input IN2 is used to start and stop the Count-
er Unit.
