carrier communication, the carrier signal received by the binary input is connected to PLC
connection point (DISCAR-R1). As a result, (External DISCAR-R1) signal will be generated.
In addition, DISCAR has the scheme switch [DisCAR-CHSEL]. By this setting, (External
DISCAR-R1) signal generation is as follows.
Single : (External DISCAR-R1) signal will be generated by only (DISCAR-R1).
And : (External DISCAR-R1) signal will be generated by (DISCAR-R1) and
(DISCAR-R1-2) for fail safe.
Guard : (External DISCAR-R1) signal will be generated by (DISCAR-R1) and non
(DISCAR-R1-2) for fail safe.
In the integral carrier communication, the received carrier signals transmitted by the
DIF_COMM function are connected to PLC connection point (INT.DISCAR-R1-*). As a result,
(Integral DISCAR-R1-*) signals will be generated.

Figure 2.12-13 How to receive carrier signals
How to receive carrier signals from the remote terminal 2 is the same.
Note: When applying UOP or BOP, the user must assign the signal "C1_BIT"
connection points shown below.
(*)"C1_BIT" is a BIT type signal that always holds 1. The Data ID of the signal
is shown in
- In the external carrier communication, assign the signal "C1_BIT" to the PLC
connection points (INT.DISCAR-R*-A), (INT.DISCAR-R*-B), (INT.DISCAR-R*-C) and
(INT.DISCAR-R*-S) that are not used in external carrier communication.
- In the integral carrier communication, assign the signal "C1_BIT" to the PLC
connection point (DISCAR-R*) that is not used in the integral carrier communication.
