General information on the evaluation of current mes-
sages on the controller
As of controller version 1.5.X, up to four currently pending messages of the control-
ler can be read out via Modbus TCP/IP. To evaluate and retrieve these messages,
the following registers have been added to the data point list:
Error Key X: This information specifies the message key.

The values can be interpreted using the document "Logamatic 5000/Control 8000
series message key list". This document is available in the ".csv" file format. This en-
ables an automated readout or processing of the message keys. You can obtain the
document from your Buderus contact partner.
Some messages contain additional information which, however, is only necessary in
individual cases. If you need this additional information for a detailed error descrip-
tion, you can contact your Buderus contact person.
