S salve number and the UPS unit or module one.
The interface is plugged in the ‘com-slots’ of the common cabinet is case of central bypass installation or in
the UPS unit 1 “com slots” in case of modular system (see bellow).
How to read data:
The identifications, status and alarms tables should be read completely in one JBUS/MODBUS frame; this
means the number of word to read is equal to the table length.
The measurements table could be read word by word, without exceed the length of the table. (from 0x1060
to 0x108F).
Incoming data structure:
Example of 6 words
1 2 3 4 5 6 7 8 9 10 11 12
MSB 0 LSB 0 MSB 1 LSB 1 MSB 2 LSB 2 MSB 3 LSB 3 MSB 4 LSB 4 MSB 5 LSB 5
