5.6.1 Examples of improper wiring
Improper wiring as shown below causes waveforms on the lines to be distorted, resulting in
communication errors. Make sure that the cables are connected properly.
Do not branch the line.
Do not make a closed loop.
Connect each cable directly to the hardware unit without passing through a terminal block.
Use cables of the same type on the same line.
The CPU module can be installed in any place.
