I am using R with PI ODBC(32bit version) to gather plant data. There is memory limit on 32bit R. So I want to use 64bit R. Recently, I installed PI ODBC 2015(64bit version, also installed PI SQL DAS). Setup of DSN of 64 bit version is different from one of 32bit version. I don't know name of PI SQL Data Access Server. How can I find out the name of PI SQL DAS. Could you give me some advices?
