EXAMPLE:
IF:
•
•In the PLC’s binary data file 3, use data elements
•Use the 6K’s binary variables
to be transmitted to the PLC. The required mapping command is:
2NTMPWB3,0,15,20
The NTMPWB command maps a range of binary data elements from the AB PLC to a range of binary (VARB) variables in the
6K. There are 125 VARB variables available in the 6K for exchanging binary data. To perform a binary 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).
3.Map a range of binary elements in the AB PLC to a range of binary (VARB) variables in the 6K (NTMPWB command).
4.Start polling the AB device at a specific polling interval (NTPOLL command). This updates binary data elements in the AB PLC with the data from the mapped VARB variables in the 6K.
Saved in Non-Volatile Memory
This command is saved in the controller’s
Potential Error Conditions:
•You are not allowed to map the same 6K VARB variables for read and write functions. Nor are you allowed to map the same 6K VARB variables to another PLC. If you attempt either of these conditions, the 6K will not accept the NTMPWB command and will transmit the error message “VARIABLE MAPPING CONFLICT…”.
•If you attempt to write to an AB data file of the wrong type, or to a
NTMPRBi,i,0,i, NTMPWBi,i,0,i, NTMPRIi,i,0,i, and NTMPWIi,i,0,i, commands).
