Scan list configuration
For configuration, the Modbus RS485 register addresses of the device parameters to be
grouped must be entered in the scan list. Please note the following basic requirements of
the scan list:
Max. entries
16 device parameters
Supported device parameters
Only parameters with the following characteristics are supported:
• Access type: read or write access
• Data type: float or integer
