Considering the possibility of installing or connecting digital or analog I/O devices directly to the PC, the Movicon system is capable of replacing the plant control device, such as the PLC (replaced by the IL Logic).

The Movicon IL Logic permits the use of PLC type logic tasks in projects for managing the control of variables or I/O.
The IL Logic (Instructions List) is the key feature of the Movicon system. This resource can has all the effects of a PLC (Programmable Logic Controller) which runs it program in background independently of the system's logic, graphic or historical engines.
The IL Logic offers a number of obvious advantages. Basically it allows you to perform any type of non-standard executions using internal PLC type programs.

The IL Logic can be associated to projects, where it is known as General Logic, or it can be associated to symbols (drawings and controls) and to screens where it is known as Local Logic. The fundamental difference between the General Logic and Local Logic are:
At project startup the General Logic is run and continues running cyclically until the project stops. The Local Logic, however, is run only when the object containing it is active, ie. when loading a screen in RAM
The General Logic run has priority over the Local Logic
The Logic is edited through the "Logic Explorer" window which displays the logic associated to the component selected at that moment.
