Introduction
The DeltaV SX Controller provide communication and control functions and integrate field devices and the other nodes on the control network. The SX and SQ Controllers provide a choice to match the controller capacity to the requirements of the process. They also provide new ease of use features that eliminate mounting screws and accelerate cabinet assembly.
Control strategies and system configurations created on earlier Deltav systems can be used with this powerful controller. The SX Controller provides all the features and functions of the M-series controllers including support for CHARM based Electronic Marshalling.
The control languages executed in the controllers are described in the Control Software product data sheet.
Benefits:
Scalable Controllers. The SX Controller complements the SQ Controller by providing additional CPU and Memory for those applications that need more control capacity:
- Late Changes:You can easily upgrade an SD Plus or SQ Controller to an SX to handle project scope changes late in the project. Simply replace the SD Plus or SQ with the SX and all existing configuration, documentation and hardware design remain the same forgiving.
- Speed: The SX Controller supports all the features you've come to expect from the DeltaV system: self-addressing, automatic 1/0 detection. All these features are designed to make your projects execute faster - just plug and play!
- Redundant Architecture: The SX Controller supports 1:1 redundancy for increased availability. Redundant SD Plus or SQ Controllers can be upgraded to SX Controllers online robust!
- Quick Assembly: The S-series hardware has been designed for speed of project execution. Carriers snap to standard DIN rails and controllers and S-series IO snap into position without the use of retaining screws.
Easy to Use.
Controllers are also easy to configure. Simply connect the SX to the DeltaV network and auto-sense it from DeltaV Explorer. Add the controller and all its IO cards to the system database and all components are automatically addressed and communicating.
- Control strategies are developed using IEC-61131 programming techniques: Function Blocks, Sequential Function Charts and Structured Text.
- Automatic diagnostics and event reporting with time stamps applied in the controller.
- Set control execution to match process dynamics and controller scheduling adjusts automatically.
- Reference any parameter by its module name, regardless of its location in the system.
- Synchronized system clock for consistent time based event driven actions across the system.
- Online expandable IO carriers allow new cards to be added online, with autosense capability, for modular system growth.
- Hardware redundancy is automatically detected with zero. configuration effort.
