Currently we have a HVAC system comprises of 3 N30 Supervisory controllers (Johnson Controls make), some application Specific controllers (Danfoss PLC Controller) and one M series workstation (Johnson Control smake). M graphics SCADA is used for real time data monitoring through OPCDA which is on M series workstation. I want to collect historical data by means of using simple script or something and store it to MS access database. Is it possible on M series workstation? and if Possible then how?
Or suggest any other way so I can pull data from any three Tap points either Workstation, N30 itself or Danfoss PLC Controller and historize?
