Sample Application

Special function blocks

Below is the list of special function blocks that the application will use:

Smart relay label

Name

 

 

Counter C1

Counts the number of vehicles in the car park (93

 

maximum).

 

 

Clock function block H1

Manages car park access hours.

 

 

Timer function block T1

Lighting timer (10 minutes).

 

 

Analog function block A1, the

Compares the CO2 level measured with the allowable

authorized threshold value

threshold.

corresponds to 8.5 Volts.

 

 

 

Timer function block T2

Fan timer (15 minutes).

 

 

Note: To implement this solution, a smart relay with analog inputs, clock function blocks and at least 4 discrete inputs and outputs.
