Function
ON when a data overflow occurred
during reception through the serial
port 2 of a CP1L EM-type CPU Unit
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 exe-
cuted.
ON when 257 bytes are received
before the end code.
ON when a data overflow occurred
during reception through the serial
port 1 of a CP1L EL-type CPU Unit 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 exe-
cuted.
ON when 257 bytes are received
before the end code.
• ON when a communications error
has occurred at the serial port 1 of
a CP1L EM-type CPU Unit. (Not
valid in Peripheral Bus Mode or
NT Link mode.)
• ON when a timeout error, overrun
error, framing error, parity error, or
BCC error occurs in Serial Gate-
way mode.
ON when the serial port 1 of a CP1L
EM-type CPU Unit is able to send
data in no-protocol mode.
ON when the serial port 1 of a CP1L
EM-type CPU Unit 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 serial
port 1 of a CP1L EM-type CPU Unit
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 exe-
cuted.
ON when 257 bytes are received
before the end code.
