Parker Hannifin 6K 사용자 설명서

Potential Error Conditions:

• You are not allowed to map the same 6K

VARI

variables for read and write functions. Nor are you allowed to map

the same 6K

VARI

variables to another PLC. If you attempt either of these conditions, the 6K will not accept the

NTMPRI

command and will transmit the error message “

VARIABLE MAPPING CONFLICT…

”.

• If you attempt to read from an AB data file of the wrong type, or read from a non-existent data element, the 6K will

not accept the

NTMPRI

command, it will transmit the error message “

ERROR, INVALID FILE TYPE, NUMBER

OR SIZE…

” and it will automatically stop polling all mapped binary and integer variables (equivalent to executing

the

NTMPRBi,i,0,i

NTMPWBi,i,0,i

NTMPRIi,i,0,i

, and

NTMPWIi,i,0,i

, commands).

Control over Polling: If you want to stop the 6K from reading integer data from the PLC, but continue to exchange

NTMPWI

NTMPRB

and

NTMPWB

data, use the

NTMPRIi,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

2NTMPRI9,15,15,35

; File 9, elements 15-29, in the AB PLC are mapped to
; the 6K's integer variables VARI35-VARI49

2NTPOLL50

; Start polling network server #2, set interval to 50 ms

WAIT(VARI40=22)

; Wait until the value of VARI40 (mapped to file 9,
; element 20, in the PLC) is 22

Network Map Integer Variables for Writing to PLC

Type:

Network

Product Rev

Syntax:

<!><n>NTMPWI,,,

Units:

n = network server #
1

i = Allen Bradley data file #

i = # of the 1

element in data file (beginning of range)

i = # of the elements to include in range

i = # of the 1

integer (VARI) variable in the 6K to map to

Range:

n = 1-6
1

i = 0-n (n depends on size of file)

i = 0 or 1-50 (0 disables polling for this mapping only)

i = 1-225

Default:

1NTMPWI0,0,0,0 (no mapping)

Response:

1NTMPWI: *1NTMPWI1,5,15,23

Range: 1-6

EXAMPLE:

IF:

• Allen-Bradley PLC is server #2

• 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:

2NTMPWI9,0,15,20

The

NTMPWI

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 exchanging integer data. To perform a integer write to 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).
