Annex A (configuration instructions)
Error code Error Cause
1 Illegal function The function code is not supported.
2 Illegal data address A register address is invalid or write-protected
3 Illegal data value A value contained in the data is not allowed or not
plausible.

6 Slave device busy The slave is busy and cannot accept the query.
Several important data points from the Modbus data point list are listed below. The entire da-
ta point list is available on request.
Data are saved in a non-volatile EEPROM. This type of memory has a limited life of at least
100,000 write operations per memory address. It is almost impossible to exceed this limita
-
tion if configurations and data are only changed manually using TROVIS-VIEW or at the de -
vice. If parameters are changed automatically (e.g. by Modbus communication), make sure
to observe the maximum number of write operations and take appropriate action to prevent
that parameters are written too frequently.
