Evaluating messages with the help of SIWATOOL
The electronic weighing system has a message buffer that can hold up to 80 entries. 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.

Detecting messages with the help of FB SIWA
All messages of the SIWAREX module can be completely detected and processed in the
controller with the help of the SIWAREX WP241 function block. The messages can be
evaluated directly in a signaling system by means of a bit signaling area in the scale data
block. The message texts are stored in the signaling system. The message text is output
when a bit becomes "1".
