MBus commissioning at FX controller

How to connect, commissioin and program MBus devices at FX-series substation

Prerequisites:

1. FX-series substation. Any of FX2020. FX2025x, FX2030x, FX3000-C, FX-Spider. 

2. multiLINK protocol converter equipped with 1 or 2 MBus ports.

mutliLINK power supply must be +24VDC in order to MBus port works properly.

3. MBus device (meter, sensor, etc.)

FX-substation configuration

First communication ports parameters shall be set:

Then we can create an MBus device object (Module):

Press "Add" button at the left pane to create, "Change" to set new parameters to existing module.

When "Message count" is bigger than zero, it means that communication is established.

mutlLINK configuration

Connect to the multiLINK  and configure it's Serial port #2 settings as following:

 

Once configured, multiLINK shall send data to corresponding Serial #2 and there shall be blinking TX LED following with blinkin RX LED. If you've got similar result, communication to MBus device has been established succesfully.

IEC programming (OpenPCS)

MBus records are translating into values by IEC program running on FX substation.

Description in FX-substation manual:

Example of a previously described MBus connection:

realVolume := GetMBUSValueF( Module:=2, Index:= 1, Divider:=0.001, Port:=0 ) ; 
realTemp := GetMBUSValueF( Module:=2, Index:= 5, Divider:=1.0, Port:=0 ) ;

(* Kamstrup warm water measurement in cubic meters, index is 1, divider is 0.001
Water temperature in Celsius degrees, index is 5, divider is 1 *)

If "index" unknown, you can detect those by analyzing MBusDebug.txt file, created at the FX-substation.

Select "Debug" checkbox and press "Change" to create a MBusDebug.txt file.

Proceed to "Settings" -> " System status"

Select MBusDebug.txt from "Debug files" lista and press "Show file" button.

In the new window/tab you will see the content of the file with all MBus messages received from corresponding MBus device "module".

Following example is received from Kamstrup warm water meter.

Data records are the actual measurements/parameters and their number order (from zero) corresponds to the "index" parameter of IEC function GetMBusValueF(). Multiplier is shown among data record properties.

As we can see, index = 0 or index = 1 shall contains consumption volume and index = 5 contains water temperature in Celsius degrees.
