C200 Control Processor Processing and Memory Resources
The C200 Control Processor provides a flexible execution environment for performing a variety of
control tasks at different execution speeds. To determine how much control a Processor can perform,
Processor Usage and Memory Usage must be considered. Available CPU and memory resources
determine the number of modules or blocks a C200 Control Processor can execute. Other constraints,
such as total number of CMs and SCMs, must also be taken into account.
These specifications should be reviewed to ensure that Experion PKS meets the application
requirements. The table below represents an example of non-redundant Control processor configuration
(not necessarily typical).

Device Control CM
Logic Control CM
Sequential Control Module (SCM)
PU = Processing Unit per Control Cycle; MU = Memory Unit, Kbytes
PUs for any given CM = (PU per Cycle) / (Cycle Time, sec.)
*Total PUs = (No. of Modules) x (Module PU) / (Period, sec.) for each CM type.
Available Period for all CM and SCM types are 0.05, 0.1, 0.2, 0.5, 1.0 and 2.0 sec. I/O Modules fixed at 0.05 sec.
**Total PUs for Non-Redundant/Redundant C200 Control Processors (Module PUs provided above apply to a non-
redundant controller, see table 17 for Module PU values for redundant controllers).
