Auxiliary Area and CIO Area in Serial Gateway Mode
Section 6-3
CTS Control
When CTS control is enabled, transmission starts when the request to send
signal (RS) turns ON after checking that the send enabled signal (CS) is ON.
When CTS control is disabled, transmission starts when the request to send
signal (RS) turns ON, without checking whether the send enabled signal (CS)
is ON.
Serial Gateway Response Timeout Monitoring Time
After a FINS command has been converted to the specified protocol and sent,
the response timeout is monitored.
0: 5 s (default); 01 to FF hex (1 to 255 decimal): 0.1 to 25.5 s
The response monitoring time can either be set to the default (0) of 5 s or to a
user-specified value between 01 and FF hex (0.1 to 25.5 s).
Note
If a timeout occurs, the FINS end code (0205: Response timeout) is
returned to the source of the FINS command. If a response is re-
ceived after the timeout, however, the message is converted and re-
turned to the source of the FINS command.
Serial Gateway Send Start Timeout Monitoring Time
When a FINS command is converted to the specified protocol and sent during
protocol macro execution, the time is monitored from when the FINS com-
mand is received until it starts to be sent in the converted protocol.
0: 5 s (default); 01 to FF hex (1 to 255 decimal): 0.1 to 25.5 s
The send start monitoring time can either be set to the default (0) of 5 s or to a
user-specified value between 01 and FF hex (0.1 to 25.5 s).
Note
If a timeout occurs, the FINS end code (0204: Remote node busy) is
returned to the source of the FINS command. Send processing will
not be executed and the received FINS message will be discarded.

Auxiliary Area and CIO Area in Serial Gateway Mode
This section describes the bits and words used by the Serial Communications
Board and Serial Communications Units in the Auxiliary Area and CIO Area
(Software Switches and Status) when Serial Gateway mode is used.
Auxiliary Area
Port 1 and Port 2 Port Settings Change Bits
These bits can be turned ON from the program using the OUT or other
instructions to change communications settings and restart the serial ports.
When changing the communications settings and restarting the communica-
tions port have been completed, the bit will be automatically turned OFF.
Note
These bits are used both to change the communications port settings and to
restart the communications port. Therefore, one of these bits can be turned
ON using an OUT instruction to restart a communications port without chang-
ing the settings in the DM Area. The STUP(237) instruction can also be used
to simply restart a communications port by executing the STUP(237) instruc-
tion with the same port settings as those already being used.
