7.10.3 Display Message
The Display message function has one Boolean input. A message
will be displayed on the CMU monitor for as long as the input value
is "1". The upper line includes the date and time of day that the
message appeared.
The text of the message is defined with the Message parameter.
This is to be found in the lower line of the display.
The Acknowledgement parameter can be used to specify that the
message will not automatically disappear with the display when the
input returns to "0", but rather that it must be acknowledged by
pressing a key. Should this eventuality occurs, then it will be
signalled by the flashing of the upper line.
Independent of that which is set with Acknowledgement, a message
can be acknowledged at any time in order that the CMU can be
operated. If the input remains at "1" however, then the message will
be displayed again after a time.
If several messages are active simultaneously, then the keys can be
used to scroll through the list of messages.

7.10.4 Switch on LED
The Switch on LED function has one Boolean input. The respective
LED will remain on for as long as the input value is "1".
The Acknowledgement parameter can be used to specify that the
LED will not automatically go out when the input returns to "0", but
rather that the LED must be acknowledged by pressing a key. The
respective LED will start to flash in such cases.
The Color parameter is used to set which LED will be switched on. 3
traffic light colors are present:
• red, • yellow • green.
Each color may only be used once in the CM program.
Depending on the specific CM device, the LEDs can also have
designations other than the names of their colors, e.g.: LED1, LED2,
etc.
