RS-232/422 Host Port
User-Defined Multidrop
Note:
Any ASCII character except
NULL
(
00
) and a
^A
(
01
) can be assigned as an
address. Control characters can be used to define RES through NAK in serial commands.
Note:
Definitions of commands in
User Defined
and
User Defined
Multidrop
must be
duplicated in host applications to enable poll and select sequences to execute correctly
during transmission.
Note:
Typically, parameters in
User Defined
Multidrop
are defined by first enabling
Multidrop
, then enabling
User Defined
Multidrop
. This pre-loads multidrop characters
into the parameters. Then changes are made to individual characters to match the host
or other requirements.
Host 422 Status
Usage:
This option is used when connecting to a concentrator or other device that
does not match standard multidrop protocol.
If selecting
User Defined
Multidrop
(7), complete the format by either
choosing new parameters or place commas where unchanged data fields
occur.
Definition:
User Defined
Multidrop
allows the user to customize the polling protocol.
Serial Cmd:
<
K140,7
,RES,address,REQ,EOT,STX,ETX,ACK,NAK>
For
User Defined
Multidrop
, first select
Multidrop
<K140,5>
, then
User
Defined
Multidrop
<K140,7...>
.
Address:
Any single character (
02
to
7E
in hex) in the ASCII table can be assigned as
the address character. The character chosen is used as the poll character
and the subsequent ASCII character becomes the select character. For
example, if a
^B
(
02
) is selected as the address,
^C
(
03
) becomes the select
address that the host will use in sending host select commands.
Usage:
RS-232 is an industry standard. RS-422 is used where greater cable
lengths are required and/or where noise interference is an issue.
Definition:
Host 422 if enabled allows communication through the 422 I/O lines.
When Host 422 is enabled, RS-232 is disabled.
When Host 422 is disabled, RS-232 is enabled.
Serial Cmd:
<
K102,host 422
>
Default:
Disabled
Options:
0 = Disabled
1 = Enabled
