*1 The RS signal setting is valid when the "RS signal status designation ( R 2 101
RYn9 ON/OFF (1)". (Refer to section 8.9.)
*2 The ER signal setting is invalid when the "Flow control designation ( R 2 100
flow control. (DTR/DSR/ (ER/DR) control) (1)".
The input/output signals (RX/RY) for the R2 master module are explained in this
section.
A list of the R2 input/output signals is shown below.

Important
Do not designate the RXn0 to RXn8, RXnE to RX(n+1)F, RYn0 to RYn9, RYnB, or RYnE to
RY (N+1)F signals to the following functions.
Monitor target RX/RY for monitor transmission function
Reference RX/RY for registration frame RX/RY/RW reference special character.
Do not output (turn ON) the usage-prohibited signals.
If an output is carried out to a usage-prohibited signal, the programmable controller system
could malfunction.
