7.1 Message types
The SIWAREX FTA messages are divided into different types.
Asynchronous messages can be generated at any time by an unpredictable
event. The internal and external hardware faults (operating messages) and the
technology messages that can occur spontaneously during a weighing procedure.
Synchronous messages are always the response to user activity.
There are data errors if a plausibility error is determined in a data package that the
user wants to send to the module and the module does not accept that data
package. These are also command errors if the module in the current operating
status cannot execute the given command.
The status displays are not messages in this respect. The status display
describes the status of the scale in normal operation and can be monitored
or evaluated at any time.
7.2 Message paths
The SIWAREX FTA messages are passed on to the user by various paths. During
project planning, it is important to choose the right path for routing and processing
the messages.
Basically, the messages are processed for two purposes:
•
For display on an operating panel
•
For connection to control software to control certain reactions in a process.
