NOTE
1. Offset position is: 20000 + N*32 + Address as shown in table, where N is unit address. Unit address as set in CSNET WEB BMS con-
guration dialog. Be careful because we are using address 0 as rst register and in Mobdus could be used number 1 as rst value. In
that case, it will be necessary to add 1 to the address calculation.
2. These numbers refer to signed 16-bit value using 2-complement format for negative values.
3. In case that the installation will use more than one CSNET WEB, it will use different device Ids, using Virtual Ids. Refer to the congura-
tion of your BMS to Ethernet adapter to know how it works.
4. Register number 10 is used for general alarm status.
