Description

Main points in the definition of a particular controller are:

  • Type of controller to be used, reflecting

– Security questions such as Hazardous applications, Emergency situations, Abnormal

operating situations, Consequences in the event of a failure, Behavior at start/stop,

Behavior at maintenance, Manual control.

– CPU performance

– Capacity requirements

– Dependability questions like Availability, Integrity

– Need for communication (Need for physical interface).

  • Type of I/O system

Centralized or distributed location of I/O is normally determined at prior and superior

design stages reflecting such questions as Maintenance, Environment, Economy (cable

savings).

  • I/O board assortment. Limitation in number of different types is often desirable.
  • Physical interface to the process. Terminal blocks, Marshalling, Hazardous applications.
  • Application of redundancy.
  • Environmental questions. Special requirement of cabinetry.
  • Mechanical design. Cabinet lay-out.

When the design work reaches this stage, the hardware and the system software for the

controller have been determined. Sufficient information should also be available to permit a

controller system configuration. The information should include a rough estimation of

application functions needed thus facilitating a dimensioning and disposition of the RAM.

The next step is to make a detailed function identification and to design the application program

based on AMPL. Finally, you implement the program.

To sum up, the main activities are:

  • Circuit identification with respect to

– Standard type circuits (typical solutions)

– User-defined type circuits

– User-defined circuits

– User-defined PC element.

  • Structuring
  • Definition of functional interface to other system
  • Execution control work-through
  • Design of start-up program which include securing of application dynamic data during

power supply disconnection

  • Configuration/Implementation

This is mostly an interactive session using an engineering station.

Some of these activities, subactivities and other similar subjects of interest are dealt with below
