EXTEND JBUS/MODBUS TABLES
For specific needs
To optimize the data traffic between the UPS and the remote equipment, DELPHYS
MX / MP
is able to
sent in one frame all information, including states and alarms, and also measurements.
The addressing map is absolute; this means that the first address defines the complete table. The next
address defines an other data table.
To use this specific mapping, you need to check if your remote system is able to manage the address
mapping independently of the length of it.

How to read data:
The identification, status and alarms tables should be read completely (this means the number of word to
read is equal to the table length).
The measurements table could be read word by word or per group, without exceed the length of the table.
