Limit

This block reads an analog input and checks it against four thresholds. If a threshold is exceeded the corresponding output

is set to true.

Parameters

The HH Limit, H Limit, L Limit and LL Limit inputs must be specified in descending order. Otherwise the

outputs HH, H, L and LL will remain low all the time.

Signal Name

In (W): Analog input

HH Limit (WP): If the analog signal In is above this value the output HH ist set to logical 1

H Limit (WP): If the analog signal In is above this value the output H ist set to logical 1

L Limit (WP): If the analog signal In is below this value the output L is set to logical 1

LL Limit (WP): If the analog signal In is below this value the output LL is set to logical 1

Delay (WP): The analog signal must remain above the threshold during the delay period at

least to activate the corresponding output.

Internally the delay time is represented as multiples of 100ms.

The max. possible delay time is 1h49m13s500ms.

If PT is left open the delay time is set to zero.

HH: High-High Output

H: High Output

L: Low Output

LL: Low-Low Output
