Function
ON while the serial port 1's commu-
nications settings are being changed
for a CP1L EM-type CPU Unit. This
flag will be turned ON when
STUP(237) is executed and it will be
turned OFF after the settings have
been changed.
ON while the serial port 2's commu-
nications settings are being changed
for a CP1L EM-type CPU Unit. This

Turn ON this bit to send a command
and receive a response for serial port 2
of a CP1L EM-type CPU Unit using the
Modbus-RTU easy master function.
Note This bit will be turned OFF
automatically by the system
when communications have
been completed.
Turn ON this bit to send a command
and receive a response for serial port
1 of a CP1L EL-type CPU Unit using
the Modbus-RTU easy master func-
tion.
Note This bit will be turned OFF
automatically by the system
when communications have

ON when one command has been
sent and the response received for
serial port 2 of a CP1L EM-type CPU
Unit using the Modbus-RTU easy
master function.

sent and the response received for
serial port 1 of a CP1L EL-type CPU
Unit using the Modbus-RTU easy
master function.
ON when an error has occurred in
communications for serial port 2 of a
CP1L EM-type CPU Unit using the
Modbus-RTU easy master function.
The error code is output to D32252
