2-2 Physical Equipment Blocks
Control Execution Environment (CEE)
Description Provides control functionality for associated Control Processor Module block. This block’s parameters characterize the
CEE within the CPM. In the future, multiple CEEs may be assigned to a single CPM.
This block always runs at an execution period of 2 seconds.
There are two versions of the CEE available, the standard version CEE-50ms, and the fast version CEE-5ms.
Function
•
Publishes parameters describing the status and configuration of the CEE.
•
Processes the computation of statistical parameters and notification reporting.
•
Runs on the CPM hardware platform. In the future, CEE will run on other platforms as well.
•
Serves as a faceplate for any parameters whose scope corresponds to that of the CEE rather than the CPM as a
whole.
•
Supports configurable subscription rate for peer-to-peer communications.
•
Supports peer-to-peer communications among CEEs assigned to CPMs located in the same management domain.
•
Sequential Control Module function blocks are supported. Special care should be taken in configuring the SCMs in
5 msec CEE.
Inputs Integrated Control Protocol (ICP) communications
