Overview MBUS



This function block can be used to read out M-BUS devices. An RS232-M.BUS gateway is required for this.


Outputs

W0-X
Meter values
Measured value read out.

Parameters

Read type
Single frame or multiframe.
Addressing
Addressing via primary address or secondary address.
ID/serial number
ID for primary address or serial number for secondary addressing.
Read interval
Interval in seconds. Please note that some meters temporarily do not respond if read out too frequently.
Interface
Interface selection
Data
Configuration of the data / outputs.

Normally not all data of the meter is always needed, therefore the data can be selected.

The dialog has two fields, on the left a list of the configured values, on the right the data fields that were read out from the meter. If the controller is connected to the gateway, the button "Read query" can be used to read out the meter. In the right window all data is displayed. With the button between the windows (left arrow) the data on the right side can now be transferred to the left side.

Only for the data on the left side are variables also generated and connected to the outputs. Optionally the data can also be created manually via the toolbar buttons +/-. For this you need to know the position within the data.
