PLC Recommendation for Profibus_PA

Greeting,
Could you please describe which one is the best PLC hardware for Profibus PA instruments SIEMENS or Allen Bradley.
As we know this protocol was invented by an engineer group of user organization in 1989, in this group there was no person which belong to Allen Bradley (as mentioned on profibus .com)
Later this protocol was owned by SIEMENS.




Thanks.

You don´t need a Profibus PA PLC.
You can have your PA network connected to a Gateway with a Profibus DP, Profinet, Etehernet/IP, Devicenet etc. master on the PLC.
Anybus, Siemens etc. have this type of gateways.
