What to Do If a Transmission Error Occurs

Condition
A transmission error is occurring.

Procedure 1
Check to see if the communication cables have been securely connected to the trans-
mission terminals of the various units, with positive (+) terminals connected to positive
(+) terminals and negative ( - ) terminals to negative ( - ) terminals.

Transmission
terminal (RS485)

Procedure 2
Check to see if the transmission cables are within the specifications range, referring to
FP2 Multi - wire Link Unit hardware manual Section 1.2.4.

At this point, make sure all of the cables in the link are of the same type, and that multiple
types of cables are not being used.
