Studio5000 CompactLogix L16ER - Physical adresses N7, F8,...

Hi folks,


In a new project, I'm trying to define variables with physical address like N7:xx, F8:xx,...
I need physical address variables to communicate CompactLogix controller with Siemens HMI Comfort.


¿Could someone tell me how to do it?


Thanks in advance.

I'm pretty sure the Comfort HMIs support tag names instead of memory addresses. But, if you really need to use addresses instead, go to the Logic menu and "Map PLC/SLC Messages..." and map the addresses to tags.

Hi,


I defined Map PLC/SLC Messages, with files 7, 8 and 3 associated with arrays of 999 elements type INT for file 7, 999 elements type REAL for file 8 and 512 elements type BOOL for file 3.


In PLC program, we are using array elements.


Siemens comfort panel is configured for ethernet/ip, but HMI output errors with these variables.


I don't know if I need to some extra configuration,...
PLC and HMI are in the same network.


Do you think that I miss something??


Thanks!!

It's been a while since I messed with Siemens HMIs, but, again, I would use the native Ethernet/IP drivers inside the HMI and just link directly to the tags in the PLC.



What errors are you getting?



In the SLC mapping, you need to tie the mapping to actual array tags in the PLC, which I assume you've done. For the BOOL file, I don't know that a BOOL array is the best way to go. I haven't tested it, but I would have it also be an array of INTs instead. If you need 512 BOOLs, that would be 32 INTs.

Hi @joseph_e2,


Problem solved.
And yes, tag names works ok with Siemens HMI.


Thanks!!!

If you don't mind sharing, what actually fixed it?

Simply use nemonic vars it's working fine. Don't use N7:00, F8:00,...

Thanks!
