I have a list of tags , for which I am using a xls file with some coding to send values to PI Server. So far so good.
But what if I have HA PI servers: sever 1 primary and server 2 secondary. Any advice how should I send from xls values to both servers.
Thanks a lot!

Hi, Ana-Maria!
How you send values in PI server? If you use VBA, then server name is written in programme code.

Yes am sending values using VBA.And yes I am mentioning the name of the server, but is the name of the PI Colective let's say server 1. but under this I have primary and secondary. Primary has the same name as the PI colective (1) and secondary has different name (2). So when I am running the macro it send only to the primary , even if force xls to be connected to secondary.

Couple of options. 1. You wait for PI SDK 1.4 where PI SDK can communicate with the PI Buffer Subsystem, which fans the data to all members of a PI Collective. 2. You have to add some code to switch PI Collective members are writing to the Primary and repeat the same tasks on the Secondary - there is an overhead to using "Switch Member". 3. Use the PI UFL interface with the PI Buffer Subsystem and change the spreadsheet to produce CSV files that are processed by UFL. Principal Consultant
