10.2 When Connecting Power Supply with + Grounding
When using with + grounding, there is a risk of short-circuit of 24V DC power supply if
connected to the PC. This is because many PCs have the communication ground (GND) and
the frame ground (FG) connected inside and short-circuit occurs through the frame ground.
Also, if controllers with different 24V DC power supplies are connected with serial
communication, the communication line may become the route of controller power supply in
some cases depending on the timing to turn on the power, resulting in the malfunction of the
communication line.
Troubleshooting is summarized separately in [ME0271 Caution for + Grounding 24V Power
Controller]. Please refer to it.
