Shifts data from
DM0010 to DM0030.
Designates the
shift start
DM No. (DM0010).
Designates the
shift end
DM No. (DM0030).
Uses the indirect addressing
function to designate DM Nos.
Clears the start DM to #0000
after the data is shifted.
The program lines which
execute the data shift
are groped as the subroutine.

signal
External reset 0008 is predetermined on hardware even if you do not specify in
the program. However, you have to set external reset enable relay 2115 to ON.

Application of Subroutine CALL
■ DM shift
Shifts the data from current DM to the next DM at UP edge of the synchronous
signal (timing).
As the number of DMs to be shifted increases, the required scan time becomes
longer.
