Single-line diagram displayed on
the LCD of ARIS C30x controller

ARIS C30x series controllers are equipped with LCD screens, and allow to create and display on it animated single-line mimic diagrams of connections. With the help of these diagrams it is possible to visualize the current status of switching devices, status of interlocking signals, position of keys, effect local or remote control of connection in real time, as well as send other signals via this connection. Single line mimic diagrams are presented on the ARIS C30x controller`s screen and can be accessed for user editing via a menu
in the web interface

Custom algorithms based on FBD

Example of algorithm implementation in ARIS C30x controller

ARIS C30x has built-in tools for programming the logic of operation. These tools can be used to create logic
and computational diagrams of any complexity, including diagrams of online interlocking of controls, logic
processing of parameters, auxiliary calculations using a custom algorithm.

For this purpose the software of ARIS C30x includes an runtime system for applications developed with help
of the functional block diagrams language (FBD). FBD allows a user to elaborate sophisticated procedures
consisting of various functional library units (arithmetic, trigonometric, logic control, PID controls, etc.). FBD
complies with the IEC 61131-3 standard issued by the International Electrotechnical Commission in 1992 that
defines the programming languages of logic controllers (PLC).

FBD integrates a structural programming methodology that allows a user to describe an automated process
in the most simple and understandable way. User functions allow to describe procedures and function
algorithms that are not implemented in the standard version.

Custom algorithms based on FBD are loaded into the ARIS C30x controller as an executable file, moreover,
changing the logic of algorithm inside the controller is not possible, one can only define bindings of
controller`s internal input and output signals. In addition to binding and processing of controller`s physical
signals it is possible to process quality attributes according to these signals.
