GOT main unit to "Disable".
• For GT14, GT11
Set the terminating resistor selector to "330 ".
For the procedure to set the terminating resistor,
refer to the following.
1.4.3 Terminating resistors of GOT
(b) YOKOGAWA PLC side
When connecting a PLC link module to a GOT, a
terminating resistor must be connected to the PC
The following describes how to connect it on the
PC link module.
Set the terminator switch (TERMINATOR) on the
front panel of F3LC11-2N to the "4-WIRE" side to
enable the terminator.
Connect the terminating resistor provided with the
LC02-0N across SDA and SDB, and across RDA
and RDB on the terminal block.
