Function
The flag corresponding to the specified FAL number will be turned
ON when FAL(006) is executed. Bits A360.01 to A391.15 corre-
spond to FAL numbers 001 to 511.
ON: That FAL was executed
OFF: That FAL wasn't executed
The flag will be turned OFF when the error is cleared.
ON when an error has occurred at the RS-232C port. (Do not
access this bit in Peripheral Bus Mode, 1:N NT Link mode, or
Serial PLC Link Polling/Polled Unit mode.)
ON: Error
OFF: No error
ON when the RS-232C port is able to send data in no-protocol
mode.
ON: Able-to-send
OFF: Unable-to-send
ON when the RS-232C port has completed the reception in no-
protocol mode.
• When the number of bytes was specified: ON when the speci-
fied number of bytes is received.
• When the end code was specified: ON when the end code is
received or 256 bytes are received.
ON when a data overflow occurred during reception through the
RS-232C port in no-protocol mode.
• When the number of bytes was specified: ON when more data
is received after the reception was completed but before
RXD(235) was executed.
• When the end code was specified: ON when more data is
received after the end code was received but before RXD(235)
was executed.
ON when 257 bytes are received before the end code.
ON: Overflow
OFF: No overflow
The corresponding bit will be ON when the serial port is communi-
cating in NT Link Mode or in Serial PLC Link Mode.
Bits 0 to 7 correspond to units 0 to 7.
ON: Communicating
OFF: Not communicating
The corresponding bit will be ON for the PT that has priority when
the RS-232C port is communicating in NT link mode.
Bits 0 to 7 correspond to units 0 to 7.
These flags are written when the priority registration command is
received.
ON: Priority registered
OFF: Priority not registered
Indicates (in binary) the number of bytes of data received when
the RS-232C port is in no-protocol mode.
