4-38
Half-duplex mode
Send command (RX/WX/ PRINT/PRINTV) runs preferentially.
(1)Mode 6B/mode 70
When the transmit command is executed, the receive mode is forcibly terminated, and the receive mode is resumed aft
er the transmit command is completed.
(2)Send and AIN commands
If the AIN command is being received when the send command is executed, the execution of the AIN command is ca
nceled.
The receiving system instruction (AIN) is not executed while the sending instruction is being sent.
(3)AIN is preferred for the relationship between AIN and conventional 70 mode reception. When AIN is not executed,
the received data enters the receiving mode of mode 70 and is stored in the port setting register. (Register top numb
er set to R7654)
Duplex mode
Since the Port2 is a three-wire RS-485, it is not supported.
Storage of received data of AIN command
(1)
The number of bytes (BCD) of received data is stored in the first register.
(2)
Received data is stored in the following register.
(3)

(4)
If the variable length AINV is smaller than the specified reception size, 20 h is stored at the end and the insufficient
reception size is filled.
(5)
The order in which the received terminal code is stored is as follows, and the terminator code 1 is stored first.
ASCII data
Terminate code 1
