Messages
Messages on the Touch Panel indicate events and statuses related to control
processes. A message consists of static text, at least. It may also contain tags.
The following types of message are displayed in plain text on the Touch Panel.
S event messages
S alarm messages
S system messages
Once issued, alarm messages and event messages are stored on the Touch
Panel in battery–backed message buffers, so they are protected against power
failures. Messages in the buffers may be called to the display and logged on the
attached printer. The Touch Panel can still be operated when messages are
waiting to be displayed.
Alarm and event messages may contain the following information:
S Arrived:
Denotes the occurrence of a message.
S Cleared:
The reason for the message no longer exists.
S Acknowledged (alarm messages only):
The message has been noted by the operator or the PLC, acknowledged and
confirmed.
A message status is accurately timed by the Touch Panel when it is recorded
and indicated when a message page or buffer is displayed.
