The reset word for the sequencer is N10:0. The first word in the
rotation of the sequencer is N10:1. The value in N10:0 must be the
same as that in N10:1. The size of file N10 is equal to the size of the
largest sequencer input file. This size depends on the number of
explicit message transfers to be performed. The sequencer length may
be expanded or reduced for run mode. It is imperative that the
corresponding file that serves as the source of the sequencer's input
file, N10, must be modified accordingly.
Failure to modify the length of file N10 for a
IMPORTANT
modification of either the Configuration or Run
sequence results in improper operation of the ladder
program, and possible FAULT of the processor due to
invalid indirect offsets.
File Data Values
Prior to running the sample ladder, the sequencer initialization file
needs to be loaded with the numbers that correspond to the explicit
message transfer sequence. The following is a list of each mode's
initialization file and the required/possible numbers to be stored in
