Function
The flag corresponding to the specified FAL number
will be turned ON when FAL(006) is executed. Bits
A36001 to A39115 correspond to FAL numbers 001
to 511.
The flag will be turned OFF when the error is cleared.
1: That FAL was executed
0: That FAL wasn't executed
ON when an error has occurred at the RS-232C port.
(Not valid in Peripheral Bus Mode, 1:N NT Link mode
or PLC Link Master/Slave mode.)
1: Error
0: No error
ON when the RS-232C port is able to send data in
no-protocol mode.
1: Able-to-send
0: 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 specified 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 exe-
cuted.
• 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.
1: Overflow
0: No overflow
• ON when a communications error has occurred at
the peripheral port. (Not valid in Peripheral Bus
Mode or NT Link mode.)
1: Error
0: No error
The corresponding bit will be ON when the RS-232C
port is communicating with a PT in NT Link or Serial
PLC Link mode.
Bits 0 to 7 correspond to units 0 to 7.
1: Communicating
0: 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.
1: Priority registered
0: Priority not registered
Indicates (in binary) the number of bytes of data
received when the RS-232C port is in no-protocol
mode.
