DSW
---
Reads the value set on an external digital switch (or thumbwheel
switch) connected to an Input Unit or Output Unit and stores the
4-digit or
8
-digit BCD data in the specified words.
I: Input Word (Data Line D0 to D
3
Inputs)
Specify the input word allocated to the Input Unit and connect
the digital switch
’
s D0 to D
3
data lines to the Input Unit as shown
in the following diagram.
O: Output Word (CS/RD Control Signal Outputs)
Specify the output word allocated to the Output Unit and con-
nect the digital switch
’
s control signals (CS and RD signals) to
the Output Unit as shown in the following diagram.
C1: Number of Digits
Specifies the number of digits that will be read from the exter-
nal digital switch. Set C1 to 0000 hex to read 4 digits or 0001
hex to read
8
digits.
C2: System Word
Specifies a work word used by the instruction. This word can-
not be used in any other application.
