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.
