Optimize the required storage size of the ADS/ADX Trend repository using the following methods:

  • configure larger sample intervals for individual trends

  • determine which trends to store long-term and transfer only these samples

  • configure the trends of non-critical objects to sample on large Change-of-Value (COV) increments

In addition, optimize the network communication performance for transferring trend samples from engines devices to the ADS/ADX repository using the following methods:

  • configure the Transfer Setpoint on individual trends so they transfer their samples at intervals different from other trends

  • use the ADS Delivery Time of the network engine to transfer the samples at the time when user access to the system is minimal
