M-Bus Master MultiPort 250D
Legacy Delay
If the master is connected to old generations of Kamstrup M-Bus modules and secondary addressing is used, Legacy
Delay shall be min. 15 seconds.
Legacy Delay ensures that the modules are ready to reply to the master when an NKE command is sent from the
master.
The above is valid for the following M-Bus modules:
• 6604 and 6607 modules for MULTICAL® III
• 6608 and 6609 modules MULTICAL® 66CDE
• 660S module for MULTICAL® Compact and MULTICAL® 401
Timing Profile
If no repeaters are connected to the master, the scanning speed can be set to Fast which improves the scanning speed
during meter search.
Timing Delay
Baud Change Delay
Baud Change Delay sets how long the master must pause scanning when
switching to another baud rate in the menu Scan All Baud.
Baud Change Delay is per default 700 ms.
Bus Collision Delay
Bus Collision Delay sets how long the master must pause before continuing scanning after a collision between a
number of M-Bus addresses.
Collision Delay is per default 700 ms.
Bus Overload Delay
Bus Overload Delay sets the delay of the internal scanner function after having detected an overload on the M-Bus
outputs. This can e.g. be caused by too many connected meters or short-circuit in the cable network.
Overload Delay is per default 700 ms.
