Errors and messages

9.3 Evaluating errors/messages with the help of SIWATOOL

9.3 Evaluating errors/messages with the help of SIWATOOL
The electronic weighing system has a message buffer that stores the last 80 entries
including time stamp in non-volatile memory. If the number of messages in the message
buffer exceeds 80, the oldest entry is overwritten. The message buffer can be read out at
any time with the help of SIWATOOL (menu item "Read out all data records") and saved
together with the scale parameters. This facilitates the detection, analysis and correction of
errors in the system. The only way to completely clear the message buffer is with the "Load
factory settings" command.

Evaluating errors/messages with the help of the function block

The electronic weighing system has a message buffer that stores the last 80 entries
including time stamp in non-volatile memory. If the number of messages in the message
buffer exceeds 80, the oldest entry is overwritten. The message buffer can be read out at
any time with the help of SIWATOOL (menu item "Read out all data records") and saved
together with the scale parameters. This facilitates the detection, analysis and correction of
errors in the system. The only way to completely clear the message buffer is with the "Load
factory settings" command.

Evaluating errors/messages using Modbus

Data record DR 32 is available for detecting and evaluating errors/messages using Modbus
(see DR 32 Error messages (Page 145)). This is updated automatically by SIWAREX and
contains a bit for each message that is set for 3 seconds when an error occurs. Thus, the
registers can be read directly by a Modbus master and the individual bits can be monitored.
In addition to the error bits, there is additional information with further details on the cause of
the error.
