ACI Historian 

The purpose of this software is to save PLC or SCADA information to a standard database (MS Access, SQL Server).  This program runs continuously on the SCADA PC and utilizes very little of the operating system resources.  The historian is setup through MS Access with "fill in the blank forms".  We currently support Opto22, Modbus, NI Lookout (Citadel) and files in CSV format.  Other drivers are available upon request.
