Appendix C - batch system capacities

The following tables contain the fixed and recommended capacities of the DeltaV Batch subsystem.

The values in the Fixed Limit column are limits imposed by the system that the user cannot exceed. The values in the Maximum Recommended Limit column are values that are recommended that the user not exceed and are to be used as a guideline when determining your system's performance.

It is important to note that the combination of items and the configuration of those items in a system and other variables (such as available memory in the controller and recipe or phase logic size) can effect whether or not a fixed or maximum recommended limit can be reached on a system; and, may also have an effect on the performance of a particular configuration. For example, a system may exceed the maximum recommended limit for one item without noticing any change in performance. However, if a particular configuration nears the maximum recommended limit of several items in combination, the potential for a change in performance is increased.

Table: Controller Capacities
Controller Capacities	Fixed Limit	Maximum Recommended Limit
PLMs per controller: non-redundant	Limited by available memory in the controller.	SQ, SD Plus, MQ, MD Plus controllers - 300 SX, MX controller - 600 PK controller - 1200
PLMs per controller: redundant	Limited by the minimum available memory between the redundant controllers.	SQ, SD Plus, MQ, MD Plus controllers - 300 SX, MX controller - 600 PK controller - 1200
Unit Phases running simultaneously per unit module: redundant and non-redundant controller	10 Unit phases can be marked as Always in Memory. This means that the phase is always able to be loaded so that it never fails to run because of over-commitment of controller memory resources.	10
Number of active phases in a controller	None	SQ, SD Plus, MQ, MD Plus controllers - 50 SX, MX controller - 150 PK controller - 300
Number of unit modules per controller	None	SQ, SD Plus, MQ, MD Plus controllers - 5 SX, MX controller - 24 PK controller - 48
Common phase logic algorithms in a single controller	None	SQ, SD Plus, MQ, MD Plus controllers - 200 SX, MX controller - 600 PK controller - 1200

Batch Executive System Capacities

A DeltaV system can include up to four enabled Batch Executives, four enabled Batch Historians, and four enabled Campaign Managers.

On Redundant Batch systems, a pair of Application Stations running the Batch Executive counts as one Batch Executive. Similarly, a pair of Application Stations running the Campaign Manager counts as one Campaign Manager.
