User-defined algorithms (interlocking algorithms) based on FBD:

Example of algorithm realization in ARIS CS controller

ARIS CS has built-in logic development tools. These tools may be used to create logical and calculation diagrams of any difficulty, interlocking, logic processing and user-defined calculation diagrams in particular. User-defined algorithms based on FBD are downloaded into ARIS CS controller as an executable file, at the same time logics of algorithm functioning is not changeable, but internal i/o signals binding can be done. Apart from binding and processing of controller's physical signals it is also possible to process data/signals quality attributes.

Environment for development of user-defined algorithms (interlocking algorithms)

Algorithm development example in Soft Constructor

Delivery package includes advanced FBD development tool - Soft Constructor. Its user interface has a windowbased interface with graphical editor and standard algorithms library. Debugging mode allows to simulate algorithm operation with supervision of variables’ status and execution flow.
