Packing Interval
Packing Interval
defines how long the unit should wait before sending accumulated characters.
This wait period is between successive network segments containing data. For alternate packing,
the default interval is
12
ms.
Trailing Characters
In some applications, CRC, Checksum, or other trailing characters follow the end-of-sequence
character; this option helps to adapt frame transmission to the frame boundary. The default
setting is
00
(none).
Send Characters
If
2-Byte Send Character Sequence
is enabled, the unit interprets the sendchars as a 2-
byte sequence; if this option is not enabled, the unit interprets them independently. The
default setting is
0
(disabled).
If
Send Immediately After Characters
is
not
set, any characters already in the serial buffer
are included in the transmission after a "transmit" condition is found. If this option is set, the
unit sends immediately after recognizing the transmit condition (sendchar or timeout). The
default setting is
0
.
Note:
A transmission might occur if status information needs to be exchanged or an
acknowledgment needs to be sent.
DisConnTime (Inactivity Timeout)
Use this parameter to set an inactivity timeout. The unit drops the TCP connection to port
10001/10002* if there is no activity on the serial line before the set time expires. Enter time in the
format mm:ss, where m is the number of minutes and s is the number of seconds.
Note*:
The default port number for Port 1 is 10001 and 10002 for Port 2. However, port
numbers may be set to a different value.
DisConnTime (00:00) ?:
To disable the inactivity timeout, enter
00:00
. Range is 0 (disabled) to
5999
seconds (99 minutes,
59 seconds). The default setting is
0
.
Send Characters
Enter up to two characters in hexadecimal representation in sendchar.
SendChar 1 (00) ? _
SendChar 2 (00) ? _
If the unit receives a character on the serial line that matches one of these characters, it sends
the character immediately, along with any awaiting characters, to the TCP connection. This action
minimizes the response time for specific protocol characters on the serial line (for example, ETX,
EOT). Setting the first sendchar to
00
disables the recognition of the characters. Alternatively, the
unit can interpret two characters as a sequence (see
Pack Control
). The default setting is
00.
