Janitza UMG 96RM-M 5222039 Data Sheet

57

The data of the parameter list and measurement values 
list can be accessed via the M-Bus interface with the 
help of the primary or secondary address. Changing 
these values is not possible via the M-Bus.

The primary device address is factory preset to „1“. 
The extended section of the 8-Byte long secondary 
address is factory preset to contain the device serial 
number and can be individually changed via the corre-
sponding parameters. The device-specific section of the 
secondary address cannot be adjusted (see page 42).

M-Bus device features
•  Addressing possible via primary address and sec-

ondary address (0 .. 250)

•  Freely selectable number of data points (0 .. 27)
•  Supports protocol types:  

SND_NKE/$E5 and REQ_UD2/RSP_UD2

•  Slave search: Search on M-Bus

C

The UMG 96RM-M loads the M-Bus with 
an M-Bus device load of 1.5 mA.

The number of data points to be transmitted for the 
RSP_UD2 telegram is defined via this address.

Address:  

080

Meaning:  

Number of data points for RSP_UD2

Setting range:   0 .. 27
Default setting:  0 (0 = All data points)

In order to call up all data points (0), a telegram must 
be sent.

Example: Read out data points 1 to 6
Set the parameter of the address to 6. With each request 
all data points up to and including data point 6 will be 
transmitted.

Example: Read only data point 10
Set the parameter of the address to 10. With each re-
quest all data points up to and including data point 10 
will be transmitted. Use only the data point required and 
ignore those that are not required.
