9.1 Message types
The messages in the electronic weighing system described here are divided into three types.
System status messages
System status messages can be generated spontaneously at any time by an unexpected
event. They include internal and external hardware problems which can occur spontaneously
during weighing.
Data and operating errors
The data and operating errors are always a response to a command due to a plausibility
check.
These are data errors if a plausibility error has been detected in a data packet which was
sent to the module and receipt of the packet has been rejected by the module.
These are operating errors if the module cannot execute the sent command in its current
operating state.
Technology errors
Technology errors occur spontaneously due to the process flow of a weighing.
Status bits, on the other hand, are not messages. The status displays describe the status of
the scale during normal operation and can be monitored or evaluated at any time.
