Parker Hannifin GEM6K manual NTFEN2 Reset, 5NTCONN1, VARB100-VARB103, 5NTPOLL50

n NTMPRI i, i, i, i

Network Server #

Range: 1-6

#of Allen-Bradley data file

#of first element in AB data file (beginning of range)

#of elements in range

#of first integer variable (VARI) in 6K (beginning of range, max value is 225)

EXAMPLE:

IF:

•Allen-Bradley PLC is server #5

•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:

5NTMPRI9,15,15,35

•Use the NTMPWB command to write up to 50 binary values from VARB variables in the 6K to binary elements in a PLC’s binary file.

n NTMPWB i, i, i, i

Network Server #

Range: 1-6

#of Allen-Bradley data file

#of first element in AB data file (beginning of range)

#of elements in range

#of first binary variable (VARB) in 6K (beginning of range, max value is 125)

EXAMPLE:

IF:

•Allen-Bradley PLC is server #5

•In the PLC’s binary data file 3, use data elements 0-14 (15 elements total) for binary data that is to be transmitted from the 6K.

•Use the 6K’s binary variables 20-34 (15 variables total) to store the data

to be transmitted to the PLC. The required mapping command is:

5NTMPWB3,0,15,20

•Use the NTMPWI command to write up to 50 integer values from VARI variables in the 6K to a integer elements in a PLC’s integer file.

n NTMPWI i, i, i, i

5NTMPWI9,0,15,20

7.Set the polling rate with the NTPOLL command. 50 milliseconds is recommended. For example, to set the polling rate to 50 ms on Server #5, use the 5NTPOLL50 command. If there is an error during polling, Error Status bit #24 will be set (see ER, TER or TERF).

;*********************************************************************

;The 6K's VARB106 will read from the PLC's File 11, element 7.

;The 6K's VARI128-VARI129 will read from the PLC's File 20, elements 5-6.

;The PLC's File 11, elements 3-6 will read from the 6K's VARB100-VARB103.

;The PLC's File 20, elements 3-4 will read from the 6K's VARI120-VARB121.
