
Bit 31:0 – Keepalive interval
These registers contain keepalive time interval in ms units. When keepalive interval is different
from 0 ms the power supply expects to be polled within a period not greater than keepalive interval
by whom last sent to it the enable command, otherwise it stops and sets communication alarm
latch. Keepalive timer resets after any successfully processed Modbus frame (frames that rise an
exception do not reset keepalive timer). Keepalive interval cannot be lower than 1000 ms, the only
exception is 0 ms which disables keepalive timer.
