Filling process run
Initialization
The following steps must be performed before the initial start of
a filling operation and e.g. in case of changes to the fill quantity:
Figure 56: Initialization
Note
The value for the outflow amount “Lag Corr. Quantity“ depends
on a number of factors (valve close time, flow velocity, pressure,
etc.) The value must therefore be experimentally determined for
every application.
Fill operation
The following steps must be performed for every fill operation:
* The digital output DO1 / DO2 must be configured as ‘Batch end contact’
for this purpose.
Figure 57: Fill operation
The current fill quantity for the present fill operation can be read
out via the Modbus address 401 “Current Batch Total.”.
The number of fill operations performed can be read out via the
Modbus address 3315 ”Current Batch Counts”. The counter can
be reset via the Modbus address 9006 “Reset Batch Totalizer”.
