page 8
The display unit reads the 9 inputs as direct contacts and the closure of each of them causes the associated
message to be displayed, The message disappears when the input reopens.
In case of several inputs closing at the same time, the display unit shows the message associated to the lower
input from D0 to D8, with priority to D0.

2.3.5. Command TYPE 11: Sub-message display in BINARY code
Using this command, you can recall a message to the second display line together with the message that is
already displayed at the moment.
This enables two different messages being displayed at the same time. Should one or both messages be longer
than 20 characters, the text will automatically scroll from right to left.
To remove the message from the second line, send back the same command recalling message no. 0.
