Hardware Category and System Limits
The Desigo CC software has a Hardware Category parameter that it uses to define system limits (the maximum number of System-Browser-tree objects that a project can have). The Hardware Category can be set to:
- EP = (embedded computer) maximum 10000 objects
- MS = (small or medium sized server/FEP) ≤50000 objects
- LS = (large-sized server maximum) >50000 and ≤150000 objects
Desigo CC then monitors how close a project is operating to those system limits, and
- Generates an alarm if the maximum permitted number of objects is exceeded.
- Prevents you from performing imports that would exceed the system limits.
- Warns you when you are approaching the system limits.
This avoids instability that may arise from overloading the hardware.
By default, the hardware category is set to MS (≤50000 objects), but you may need to adjust this value to EP or LS to match the actual scale (number of field devices and subsystems, and so forth) of the installation you are configuring.
The System Description document (A6V10415500) details the criteria for determining the system dimensioning, and the hardware requirements for each category.
For instructions, see Configuring Hardware Category and System Limits.
Hardware Category and System Limits Properties
In Engineering mode, when you select the Main Server object in System Browser, information about the hardware category and system limits displays in the Extended Operation tab.
The various properties and commands of the Main Server object, which also include those relating to the hardware category and system limits.
If the project only slightly exceeds the maximum system objects for its hardware category, contact Customer Support to increase the System Objects Limit for that category.
However, if the number of objects is significantly above the limit, the project must be adjusted to a higher category, which may also require an upgrade of the computer hardware. Contact Customer Support for assistance.
Details of these properties are provided in the following table.
Property | Description | Commands | |
---|---|---|---|
System Objects | Total number of objects currently configured in the system. This value is automatically checked and updated every 60 seconds. | - | |
System Objects Limit | Maximum number of objects the project can have. Its value is determined by the Hardware Category. | - | |
Hardware Category | System Objects Limit | ||
EP | 10000 | ||
MS (default) | ≤50000 | ||
LS | >50000 and ≤150000 | ||
System Load | Loading of the system with respect to the system limits.
| - | |
Hardware Category | System limits (maximum permitted objects) and should be set to match the actual hardware category (EP, MS, or LS) of the installation, as specified in the System Description document. |
| |
Notification Threshold | Safety threshold with respect to the system limits. See System Load, above. | - | |
