Chapter 13 Troubleshooting

(h)Peripheral units problem

Peripheral units cannot be connected.

Is it a fatal CPU error?

Are the connection

cable type, continuity

and connector

connections normal?

YES

Are the CPU

communication setting

correct?

YES

Is there 5 V DC output when a 5 V DC power supply is required?

YES

Replace the connection cable

YES

Expansion connector check

Expansion cable check

Correct the setting

Set the CPU DIP SW to the communication speed of the peripheral unitused

Broken fuse

∗Fuse replacement may not be performed by the user, so a replacement request must be submitted

Please contact our service department.
