The
NTPOLL
command is not saved in the 6K’s non-volatile memory. If you wish the 6K to re-establish the
NTPOLL
polling
rate when you cycle power or issue a
RESET command
, put the
NTPOLL
command in the startup program assigned with the
STARTP
command.
Example:
2NTIP1,172,54,125,34 ; Identify network server #2 as an Allen-Bradley PLC at
; IP address 172.54.125.34
2NTCONN1 ; Attempt connection to network server #2
2NTMPRI20,5,2,128 ; File 20, variables 5 and 6 in the AB PLC are mapped to VARI128
; and VARI129, respectively
2NTPOLL50 ; Start polling network server #2, set interval to 50 milliseconds
NTRATE
Network Sharing Rate for Peer-to-Peer Communication
Type:
Network
Product Rev
Syntax:
<!>NTRATE<i>
Units:
i = milliseconds
Range:
0 (off) to 1000 (50 milliseconds is recommend)
Default:
0 (off)
Response:
NTRATE: *NTRATE50
See Also:
NTFEN, NTID
,
SYSPER, VARSHO, VARSHI
6K 5.3
Use the
NTRATE
command to establish the broadcast rate for
VARSHO
information packets to other 6K units. With
NTRATE0
, broadcasting and listening to other units that are broadcasting is disabled. With a value > 0, it is enabled. A rate
of 50 is recommended. All sharing units should have the same
NTRATE
.
NTRATE
is not accepted unless the 6K is operating
in
NTFEN1
mode.
Each 6K unit internally updates its
VARSHO
data at the System Update Rate (2 milliseconds); therefore, the
NTRATE
command must be set to a value of
≥
2 milliseconds. If you lengthen the System Update Rate (see
SYSPER
), increase the
NTRATE
value accordingly.
The
NTRATE
command is not saved in the 6K’s non-volatile memory. If you wish the 6K to re-establish the
NTRATE
broadcasting rate when you cycle power or issue a
RESET command
, put the
NTRATE
command in the startup program
assigned with the
STARTP
command.
Example:
; *************************************************************************************
; Send these setup commands to 6K unit #1
NTID1 ; Set unit 1's network ID to 1
NTRATE50 ; Unit 1 will broadcast at 50-millisecond intervals
; *************************************************************************************
; *************************************************************************************
; Send these setup commands to 6K unit #2
NTID2 ; Set unit 2's network ID to 2
NTRATE50 ; Unit 2 will broadcast at 50-millisecond intervals
