Parker Hannifin GEM6K - Manual (Page 28)

Control over Polling: If you want to stop the 6K from writing binary data to the PLC, but continue to exchange NTMPRI ,
NTMPWI and NTMPRB data, use the NTMPWBi,i,0,i command. If you need to stop polling all mapped variables, use the
nNTPOLL0 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
2NTMPWB3,0,15,20 ; File 3, elements 0-14, in the AB PLC are mapped to
; the 6K's binary variables VARB20-VARB34
2NTPOLL50 ; Start polling network server #2, set interval to 50 ms
VARB25 = b1111000011110000 ; The value of AB file 3, element 5, will be set to
; 111000111000, because it is mapped to VARB25

EXAMPLE:
IF:
• Allen-Bradley PLC is server #2
• The PLC’s integer data file 9 has 30
elements. Use data elements 15-29
(15 elements total) for integer data
that is to be shared with the 6K.
• Use the 6K’s integer variables 35-49
(15 variables total) to store the data
from the PLC.
The required mapping command is:
2NTMPRI9,15,15,35
The NTMPRI command maps a range of integer data elements from the AB PLC to a range of integer ( VARI ) variables in
the 6K. There are 225 VARI variables available in the 6K for storing integer data. To perform an integer data read from the
PLC:
1. Assign the AB PLC a server number, according to its IP address ( NTIP command).
2. Connect to the AB PLC, according to its server number ( NTCONN command).
3. Map a range of integer elements in the AB PLC to a range of integer ( VARI ) variables in the 6K ( NTMPRI
command).
4. Start polling the AB device at a specific polling interval ( NTPOLL command). This updates the 6K integer ( VARI )
variables with the integer element data from the AB PLC. You can then use the PLC integer data (via the VARI
variables) in conditional expressions, command value substitutions and variable assignments.
Saved in Non-Volatile Memory
This command is saved in the controller’s non-volatile memory, and is remembered on power-up
and RESET.
