DM Area Allocations (Using Serial Gateway Mode)
Section 6-2
Note
The following operations will result if the Serial Gateway is executed either
using a pre-Ver. 1.2 Board/Unit or using a Ver. 1.2 or later Unit/Board without
Serial Gateway or protocol macro mode set for serial communications at the
serial port.
• If either NT Link or loopback test mode is used for serial communications,
or if protocol macro mode is used with a pre-Ver. 1.2 Board/Unit, an unde-
fined command response will be returned (end code: 0401 hex).
• If Host Link mode is used for serial communications, the message will be
converted into a FINS command using Host Link slave-initiated communi-
cations and transferred (this will mainly result in a response timeout being
returned, depending on the remote device (end code: 0205 hex))

DM Area Allocations (Using Serial Gateway Mode)
This section explains the Setup Area (words allocated in DM Area) when a
Serial Communications Board or Serial Communications Unit is used in Serial
Gateway mode.
Setup Area Words
The Serial Communications Boards and Serial Communications Units use the
following words as a Setup Area in the DM Area when Serial Gateway mode
is used. The words allocated to the Serial Communications Board are differ-
ent from those allocated to the Serial Communications Units, which are allo-
cated words according to the unit numbers.
Serial Communications Boards (CS Series Only)
Words are allocated in the DM Area from D32000 to D32099 as the Setup
Area for the Serial Communications Board as follows:
Send start timeout
monitoring
The time is monitored after a FINS command is received and
converted into another protocol until transmission starts (pro-
tocol macro mode only).
Default: 5 s; Setting range: 0 to 25.5 s
Note
If a timeout occurs, the FINS end code is returned to the
source of the FINS command (0204 hex: Remote node
busy). Send processing is not executed and the
received FINS command is discarded.
Send delay
The time after protocol conversion using the Serial Gateway
until actual data is sent can be set (Serial Gateway mode or
protocol macro mode only).
Default: 0 s; Setting range: 0 to 300 s
