Advanced I/O Instructions (CQM1 Only) Section 2-2
The following example illustrates connections for an A7B Thumbwheel Switch.
The inputs can be connected to the CPU Unit’s input terminals or a DC Input
Unit with 8 or more input points and the outputs can be connected from a
Transistor Output Unit with 8 or more output points.
Preparations When using DSW(87), make the following setting in the PC Setup in PRO-
GRAM mode before executing the program.
