Gemini GV6K and Gemini GT6K Programmer's Guide

Network Server #
Range: 1-6
n NTMPRB i, i, i, i
# 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
• The PLC’s binary data file 3 has 30
elements. Use data elements 15-29
(15 elements total) for binary data
that is to be shared with the 6K.
• Use the 6K’s binary variables 35-49
(15 variables total) to store the data
from the PLC.
The required mapping command is:
5NTMPRB3,15,15,35
• Use the NTMPRI command to read up to 50 integers elements from a PLC’s Integer
file and write them to VARI variables in the Gem6K.
Network Server #

n NTMPRI i, i, i, i
# 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
Gem6K to binary elements in a PLC’s binary file.
Network Server #
Range: 1-6
n NTMPWB i, i, i, i
# 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 integers values from VARI variables in
the Gem6K to a integer elements in a PLC’s integer file.
Network Server #
Range: 1-6
n NTMPWI i, i, i, i
# 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 0-14
(15 elements total) for integer data
to be transmitted from the 6K.
• Use the 6K’s integer variables 20-34
(15 variables total) to store the data
to be transmitted to the PLC.
The required mapping command is:
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).
