4.5 Messages and log book
The IQ S ENSOR N ET continuously monitors the status of the entire
system. If the IQ S ENSOR N ET identifies system changes, a message
appears. New messages can be recognized by the flashing information
symbol or error symbol on the display.
All messages are recorded in the log book.
In addition, a flashing status LED at the MIQ/TC 2020 XT reminds you
that there is an error or alarm (see section 1.3.5).
4.5.1 Message types
The system differentiates two types of messages:
 Errors h
Indicates a critical status in the system or an individual system
component that requires immediate action.
In the case of new error messages, the error symbol flashes on the
display.
 Information i
Information that does not require immediate action.
In the case of new information, the info symbol flashes on the
display.
Note
In the case of errors, immediately open the detailed message text in the
log book and perform the recommended actions. If the actions have
been performed, mark the message as read (see section 4.5.3).
4.5.2 Log book
The log book is a list with all the messages from all modules. The log
book contains up to 1000 entries. If there are more than 1000
messages, the oldest entries are deleted.
New messages can be recognized by the flashing information symbol
or error symbol. The log book always contains the latest message in the
first position. They do not yet have a checkmark in the status field.
The flashing of the info or error symbol only stops after all detailed
message texts in the log book have been opened and marked with a
checkmark (
✔) (see section 4.5.3).
