4-2 Examples
1. Installation
Connect the Units. When necessary, install a Memory Card.
Make sure that the total power consumption of the Units is less than the max-
imum capacity of the Power Supply Unit.
2. Wiring
Connect the power supply and I/O wiring.
3. Initial Settings (Hardware)
Make necessary hardware settings such as the DIP switch settings on the
CPU Unit. In particular, be sure that the settings for the peripheral port and
RS-232C port are correct.
In the following example, a Programming Console is connected to the periph-
eral port so pin 4 is turned OFF. A Programming Device other than a Pro-
gramming Console is connected to the RS-232C port, so pin 5 is turned ON.
