(6) Other PLC and Microcomputer connection

It is necessary for the user to create the cable used to connect GOT with a PLC or a microcomputer 
from another company (RS-422 cable or RS-232C cable).
Refer to the GOT-A900 series User’s Manual (Connection System Manual) for information about 
the cable creation method.

When connecting GOT to a PLC or microcomputer from another company, configure 
the system so that the EMC directive specifications from the connection destination 
are applicable.

The contents shown below are a collection of the contents that should be enforced 
when made applicable to the EMC directive; however, the final decision to make the 
device applicable to the EMC directive and how to make it applicable must be made by 
the manufacturer of the machine device.

(a) For RS-422 cable

• Each signal wire (excluding SG and FG) should be made into a two power wires and 

connected, then twisted.

• Make the SG wire more than two wires and connect.
• Wrap the cable shield material around the cable, so that the back aluminum foil side (shield 

side) of the cable shield material is exposed at both ends of the cable.

*1 The back aluminum foil side of the cable shield material (shield side) should be exposed. (Refer to Section 8.3.2 (1)
