Scan configuration
Options:
The M-Bus first needs to be scanned for the Energy Analyzer to detect connected devices. This
scanning process uses either primary or secondary addressing.
Primary: If you select this option, the search for devices connected is based on their primary
address. The primary addresses must be set beforehand on the relevant device (M-Bus slave).
Note
The primary address is pre-set to 0 on ABB meters in the factory.
Each M-Bus device must be assigned a unique primary address. Duplicate addresses cause address
conflicts!
Speed range (baud rate)
Options:
Sets the speed range used for scanning for M-Bus devices connected. Communication with M-Bus
devices is only in this range. The speed range set here must match the speed set on the M-Bus
slave. Otherwise the system cannot detect any devices. The speed can be set based on meter
type.
Note
ABB meters are supplied from the factory with the speed 2400.
You should limit the scan range as much as possible. The wider the speed range, the longer the
scanning process takes.
Address range
Options:
Sets the limits for the primary address range. This parameter is only visible if Primary is selected.
Note
The wider the range, the longer the scanning process takes.
