Hi, I'm developing a application thats need read and log a large tag database at period of 1 second. My system have actually 1200 tags and when I try to increase the number of tags my system slowdown and not update at requested period anymore. I'm using NI OPC Servers to read data of 4 different PLC's. In the SVE I've created an IO Server to bind variables and all variables are located in a single process. All variables are logging alarms and data. The Log Deadband and Update Deadband are set to 0. My machine is a DELL Precision T5400 with Dual Intel Xeon Quad Core with 4GB of RAM and Windows XP Sp3 installed. Bruno Costa Automation Enginner
