Short description

This function displays message texts and parameters of other blocks on the LOGO! onboard display when LOGO! is in RUN mode.

Connection

Description

Input En

A 0 to 1 transition at En (Enable) triggers the output of the message text.

Input P

P is the priority of the message text.

0 is the lowest, 30 the highest priority
Ack: Acknowledgement of the message text

Parameter

Text: Input of the message text
Par: Parameter or actual value of another, already configured function (see "Visible parameters or actual values")
Time: Shows the continuously updated time-of-day
Date: Shows the continuously updated date
EnTime: Shows the time of the 0 to 1 transition
EnDate: Shows the 0 to 1 transition of the date

Description of the function

With a 0 to 1 transition of the signal at input En, the display outputs your configured message text (actual value, text, TOD, date) in RUN mode.

Acknowledgement disabled (Ack = Off):

The message text is hidden with a 0 to 1 signal transition at input En.

Acknowledgement enabled (Ack = On):

After input En is reset to 0, the message text is displayed until acknowledged by pressing the OK button. The message text cannot be acknowledged as long as input En is high.

If several message text functions were triggered with En=1, the message with the highest priority (0 = lowest, 30 = highest) is displayed. This also implies that a new message text is only displayed if its priority is higher than that of previously enabled message texts.

After a message text is disabled or acknowledged, the function automatically shows the previously active message text that takes the highest priority.

You can change between the display in RUN mode and the message texts by means of the and buttons.

Restrictions

Up to ten message text functions are available.
