Display Activation | Schneider Electric SR2MAN01 instruction

LD Language Elements

Used as a Coil Two coils are associated with each Text block:

zDisplay Activation coil,

zDisplay Deactivation coil.

The use of these coils is described below.

Display Activation

Symbol of the Display Activation coil of a Text function block:

TX -

This coil displays on the screen the text and/or the values of the associated Text block when the contacts that are connected are conducting.

Display deactivation

Symbol of the Display Deactivation coil of a Text function block:

RX -

This coil deactivates the display of the text and/or the values of the associated Text block when the contacts that are connected are conducting. The display returns to the inputs-outputs screen.

Example:

I1		TX1

I2		RX1

Activation of input I1 displays the text on the LCD. Activating input I2 makes the text disappear.

Parametering The Text function blocks are only programmable from the programming software, see the on-line help for the programming software for more information.
