Overview
The Honeywell ControlEdge HC900 Controller is an
advanced loop and logic controller offering a modular
design sized to satisfy the control and data management
needs of a wide range of process equipment. When
combined with the optional 900 Control Station operator
Interface that is highly integrated with the controller’s
database, configuration and setup time is minimized. This
powerful combination together with Honeywell’s

In general, needed to execute the total configuration is recalculated. If
Maximum I/O channels = (max. number of I/O racks) x additional time is needed, the scan time will be increased to
(max. number of modules in each rack) x the next increment in sequence. (See Specification section
(max. number of channels per module) for scan time increments)
Examples
How many recipes in my pool?
Maximum C30 I/O = 1 rack x 12 modules x 32
Unlike with function blocks, there is no quantity limit to

14 ControlEdge HC900 Controller

The rule of thumb is Controller Data Storage

Max. number of recipes = Recipe memory allocation ÷ The controller may log process data values in the available
memory per recipe memory that is not used by the configuration. Up to 250
signal values may be logged in a rotating buffer using three
Configuration memory allocation
different sample rates with oldest data being replaced with
The configuration memory comprises one allocation for
new data after the buffer is full.
the function block configuration and one allocation for
recipes. Data is extracted from the controller using HC Historian data
In general, harvesting software via Ethernet or Serial connection.
Total configuration memory =
Configuration + Recipe allocation

Whatever memory has not been allocated to recipes is

available for your configuration. By changing the size
of the recipe pool allocation, you control the amount of
memory available for recipes and therefore
configuration. Need a small configuration but many
recipes? Allocate more recipe space. Need a large
configuration but few recipes?
Allocate less recipe space.

Where are usage/capacities presented?

File Properties in Designer displays statistics on
usage/availability of:
• configuration memory (recipes + function
block configuration),
• dynamic memory (function block configuration
only)
• fast scan time,
• Normal scan time,
• Normal CPU% used,
• Fast CPU% used,
• Each component of a configuration (variables,
constants, etc.).
