REMARKS
When performing online exchange
The built-in terminating resistor can not be exchanged online since the terminating resistor is on the FR-A7NC board and
disconnected when the terminal block is removed from the FR-A7NC connector for communication. When changing the FR-
A7NC online, connect a terminating resistor supplied with a PLC master module to the FR-A7NC after modifying it and do
not use the internal terminating resistor (SW2 1-OFF, 2-OFF).
Connection with the terminating resistor
Connect the terminating resistor between terminals
DA-DB of the FR-A7NC at the end.
Modify the terminating resistors supplied with the
PLC to use.
When a resistor is not supplied with the master unit,
use a resistor with 110Ω1/2W available on the market.
