Variables Area

Process Control variables area is a code editor for ST language with analyzer and embedded prompt messages.

Contains information of:

- program component variables.

Further they will be employed in program body for calculation. After variable creation and program analysis, it can be accessed by user and will be added to screen tips list.

- GPIO (general-purpose input/output) of device variables.

This is low-level I/O interface for direct operation. Via this interface, device connected to Iotellect can listen and order any outer device such as sensor, diode, etc.

- ADC (Analog-to-digital converter) of analog device variables.

If device contains ADC converting input analog signal into discrete code (digital signal), you can use variables of corresponding range.

Usually from -10 000 to 10 000 mV.

Variables are described in ST language, their values can be assigned to GPIO and analog variables, as well as program itself. Device variables can be accessed if device context was chosen during program configuration.
