Sequencing Instructions
The following table shows Sequencer instructions of internal data.
SEQIC - Sequencer Input
Compare
Instruction Type: output
If rung state is true, the SEQIC instruction is used to compare IN data and
masked source at the data table. If the data is matched, it sets Found flag in the
CR data table specified as CTRL.
When the FOUND flag is set, the FOUND flag indicator turned green on the
ladder program.
The following figure explains how the SEQIC instruction works.
Instruction
Description
SEQIC
Sequencer Input Compare
If rung state is true, compare IN data and masked source
at the data table. If the data are equal, it sets Found flag in
the CR data table specified as CTRL.
SEQO
Sequencer Output
If rung state is true, data table value in the POS and
masked value are logically ANDed, then, copy the data to
the destination data table. If copy is done, Done flag in the
data table specified CTRL is set.
SEQL
Sequencer Load
If rung state is true, load data table values specified IN to
the data table specified by POS sequentially. If copy is
done for a give
N
length, it sets DONE flag in the CR data
table specified as CTRL.
IMPORTANT
Data table and Masked source data type must be same.That is,
if the data table is an integer(N), Mask and IN must be
integer(N).
