The following diagram shows the connection between the GOT and the PLC.
(1) RS-422 connection diagram 1)
*1 A terminating resistor is required.
Set the terminating resistor selector switch in the main unit to “Disable”, and connect a terminating resistor (110 Ω).
1.4.3 Terminating resistors of GOT
*2 For terminating resistors in PLCs manufactured by MITSUBISHI INDIA, refer to the manual of PLCs manufactured by
MITSUBISHI INDIA.
*3 Use a twisted pair cable for the SDA1/SDB1.
(2) RS-422 connection diagram 2)
*1 A terminating resistor is required.
