Parameters like: Retry Count, Initialization Delay, Response Timeout and Inter Message
Delay are used in the device discovery action. If it is required these parameters can have
different settings in devices than the network (devices connected to the bus can have
different communications parameters).
8 M-Bus IP Device
The M-Bus IP Device is a component for servicing the M-Bus devices connected to the M-
Bus IP gateway. All types of the iSMA-B-AAC20 devices can use this type of communication.
There are two ways to add the M-Bus IP Device to the application:
•
Manual: By drag and drop from the Sedona Palette to the network component. In this
case, user must know the M-Bus device address (Primary or Secondary).
•
Automatic: By using the discovery action in the network component. For the first
commissioning, it is recommended to search by the Secondary Address and then assign
the Primary Address. All new devices have factory default Primary Address set to 0.
WARNING! ALL discovered devices are placed in the DiscoveredDevices folder. In this folder,
devices are read only once for normal use and they must be moved from this folder and
placed directly or to another MbusFolder under the MbusLocalNetwork component.
