Field Controller System Capacity Calculations

Important: When you upgrade from Release 5.x to Release 6.0 or later, or use the System Selection update as part of your upgrade process, the calculated object count may increase, which could potentially exceed system capacity. For more information on object counts and calculating system capacity, see System Capacity Indicator.

Output Controller Module Upgrades

  • Starting at Release 5.1, the tool updates Output Controller modules (including custom and user-modified modules) that contain PID and PID Pre-Processor logic block changes:

    • The tool fully upgrades Output Controllers used with Proportional Outputs with the latest logic and all of the necessary internal connections.

    • The tool upgrades Output Controllers used with Staged/MSC Outputs with the latest logic block changes; however, the tool is unable to make the connections between the blocks if they do not reside at the same level within the module (for example, the PID exists inside a Hybrid Activity, but the PID Pre-Processor exists outside of the Hybrid Activity within the module). Instead, the PID logic blocks calculate their starting tuning parameters from the time constant and deadtime.

    • The tool upgrades Output Controllers for 2-Pipe (Common Heating/Cooling Coils) with the latest logic block changes; however, the tool does not make the connections between the blocks. Instead the PID logic blocks calculate their starting tuning parameters from the time constant and deadtime.

  • Starting at Release 5.1, when you rerun System Selection, the tool adds four EWMA parameters that are automatically exposed to all of the Output Controllers doing Zone Control (VAV Boxes, Fan Coils, Unit Vents, and Heat Pumps).

  • Starting at Release 5.1, the tool makes changes during the upgrade process for Chiller Plant Automation (Central Cooling with Optimization) enhancements. The tool updates the Chiller Selector for more efficient chiller selection, accounting for capacity at more or less than the designed chiller lift, support for all 24 of the large tonnage standard configurations and sequences, and to work with the new Cooling Tower Selector.

  • Starting at Release 5.1, when you rerun System Selection for Chiller Plant Automation (Central Cooling with Optimization) applications, you can add support for variable speed condenser water pumping. The tool adds a Variable Speed CW with Low Limit v61 Output Controller, pressure flow and temperature AIs, and AOs.

Custom or Manual Tuned PID Value Upgrades

Starting at Release 5.1, select custom-set attributes of the PID Pre-Processor are reset to default values after opening or upgrading the CAF in a later release of CCT.

PID Attributes affected are:

  • Proportional Band

  • Integral Time

  • Derivative Time
  • Saturation Time
  • Deadband
  • Interval

Accumulator Attributes affected are:

  • Periodic Update (Release 4.1 and later)
  • Update Interval (Release 4.0 and earlier)
Note: The Update Interval attribute became the Periodic Update attribute at Release 4.1.

For more information on PIDs, see the Pattern Recognition Adaptive Control (PRAC+) Overview section. For more information on preserving the PID values, see the Preserving PID Values Reset by Upgrading or Opening CAF in Post 5.1 Release Environments section.
