Honeywell ControlEdge HC900 Controller Controlware 900U02-0100 spot goods

Overview ControlEdge HC900 Controller Controlware is the execution  environment, control algorithms and firmware infrastructure  programmed into the controller’s memory to allow users to  apply the product in process control applications. Operation A control strategy configuration in the ControlEdge HC900 controller consists of function blocks, or predefined  algorithms that get executed in a sequential manner during a  scan cycle. During controller configuration, the user specifies  the quantity and type of function blocks needed for the  application.  Two scan engines (Fast and Normal) contain the specific  function blocks and the execution sequence to run its blocks.  Physical inputs are read at the start of each scan cycle, then  all function blocks are executed according to the execution  order, then physical outputs are updated. Due to their  nature, TPS, TPO and PPO functions have their physical  outputs updated during their execution. The execution environment for the controller is based on two  deterministic execution cycles, one for fast logic type  operations and a second cycle for normal analog based  operations. Within these two fixed time cycle operations,  time is allocated by the system to execute other functions  such as communication tasks, and background diagnostic  checking. These tasks are assigned function block numbers  1 through 100 and may not be altered by the user. The  user’s configuration begins with function block number 101. In order to maintain the deterministic operation of the  controller, time may be added to the scan cycles in fixed  increments based on the size and scope of the user’s  configuration. The maximum time required to execute the  user’s configuration is determined when a configuration is  loaded into the controller and does not change during online operation.  The time needed to execute communications and other  background tasks is accounted for in the configuration timing  and does not impact the deterministic operation of the  controller.

Controller Configuration 

User configurations are permanently retained in flash memory  in the controller. In the event a PC configuration file is lost or  misplaced, it can be easily reconstructed using the upload  function of the Designer configuration software or via the 900  Control Station. Simply read the configuration from the  controller to exactly duplicate the original configuration,  including all text descriptions. In the event edits to a  controller’s configuration are required after the unit is in  operation, the on-line download function of the ControlEdge  HC900 Designer software allows configuration changes while  in the Run/Program mode, limiting process disturbances.  During power interruptions to the controller the dynamic  control status is retained in battery backed RAM memory. This  function minimizes process upsets during momentary power  interruptions and other discontinuous operation. If power is  lost and the battery is not available, the controller defaults to  the configuration stored in Flash memory and a cold start is  performed. 

Function Block Attributes 

The CPUs of the ControlEdge HC900 provide different  function block capacities to allow matching controller  performance to application needs. The C30 CPU provides up  to 400 function blocks, the C50 up to 2000, and the C70/C75 up to 15000 (5000 for version below 6.6) function blocks. Similar proportions apply to available support items such as  soft-wire connections and page connectors.
