Monitoring and Accumulating Flowrate

Block address
160
Function blocks used: PI 4-point Terminal (Block Model 562)
Connect the instantaneous value output value of the PI 4-point Terminal
block to the Accumulator for instantaneous value input block when
accumulating 8-digit accumulated values based on the instantaneous values
from the Pulse Input Unit CS1W-PPS01.

Note 1 This instantaneous value differs from the instantaneous value, that is
reflected in the allocated relay words n+1 to n+4 of the Pulse Input Unit
CS1W-PPS01, in that the instantaneous value is for each operation cycle of
the PI 4-point Terminal block.
Accumulator for instantaneous value input (Block
Model 150)
Let's apply scaling of 0 to 6000 to zero (0%) through to span
(100%) of the pulsse input instantaneous value, and set
accumulation to maximum 1200.00 per hour. (The accumulated
value is taken to be 1200.00 when 6000 has continued for 100%
for one hour.) The accumulation result is stored to ITEM012 and
ITEM013 of the Accumulator for instantaneous value input block.
