Zoomed view:
The zoomed view remains active for as long as you hold the Data
Release key down. With smaller displays (for example, with 4 x 20
characters) only the message text is zoomed. The device type that is to
be used must be considered when the text is programmed, to ensure
the lines are wrapped correctly.
5.22.5.9 Acknowledging Messages
Message acknowledgment in the controller can be carried out by
means of variables. Various editors or function keys (soft keys) are
suitable for this purpose. The acknowledgment enables the controller
to delete the message and initiate another verification.
5.22.6 Serial Message System
Two bytes are reserved in the cyclical polling area for the transfer of
serial messages. These two bytes are referred to as the 'serial mes-
sage channel'. The byte order depends on the selected data type of the
polling area (see Polling Area). The controller writes a 16 bit message
number in this message channel.
The operating device polls the entire polling area of the controller at
cyclical intervals and transfers the serial message in the process.
Upon detecting a message (message number > 0), the operating
device stores this message in the internal message memory and resets
the serial message channel in the controller to zero (0). The value 0
indicates to the controller that the message has been picked up by the
