313/314 R Float 1 0-4294967040 Pulse Counter 1 (Import Real Energy)
Contact closure counters. Valid for both pulse
inputs and outputs. EM3555 counts are shown in
parentheses. See register 144 for the weight of
each pulse output count. These values are derived
from the 32 bit integer counter and will roll over to
0 when the integer counters do. Inputs are user
dened.
