7.1 Message types
The SIWAREX U messages are divided into several types.
The asynchronous messages (see Chapter 7.8) can arise spontaneously at any
time due to an unforeseen event. This includes internal and external hardware
faults (operating faults), which can arise spontaneously during a weighing.
The synchronous messages (see Chapter 7.7) always arise in response to a
command.
There are data errors when a plausibility error was detected in a data package
which was sent to the module and the acceptance of the data package by the
module is refused. These are command errors if the module in the current
operating status cannot execute the given command.
The status bits (see Chapter 5.8.2) on the other hand are not error messages at
all. The status describe the status of the scale in normal operation and can be
monitored/evaluated at any time.
7.2 Message paths
The SIWAREX U messages reach the operator over different paths. During
configuration, it is important to choose the right path for routing and processing the
messages.
Essentially, the messages are processed for two purposes:
• For display on a control unit
• For the control software to control certain reactions in the process.
