BATCHING_QUANTITY module
The value of the quantity to be batched (IEEE 754 floating point number), including status,
can be cyclically transmitted by the PROFIBUS master (Class 1) to the measuring device
using the BATCHING_QUANTITY module (slot 8). If the batch quantity specified here is
achieved, the closing contact for valve 1 is activated. The unit selected in the measuring
device is used as the unit.
"
Caution!
The batching quantity is a nonvolatile device parameter. For this reason, avoid constantly
writing this device parameter via PROFIBUS! → 104
!
Note!
• This module is only evaluated by the measuring device if the additional "batching" software
is installed in the measuring device (order option).
• Further explanation of the parameter BATCH QUANTITY (7203) is contained in the
"Description of Device Functions" manual, which is a separate part of this Operating
Manual.

BATCHING_FIX_COMP_QUANTITY module
A positive or negative correction value (IEEE 754 floating point number), including status,
can be cyclically transmitted by the PROFIBUS master (Class 1) to the measuring device
using the BATCHING_FIX_COMP_QUANTITY module (slot 9). The correction quantity
balances out a constant, system-related incorrect quantity. This can be caused, for example,
by a pump over-running or by the closing time of a valve. The correction quantity is
determined by the system operator. A negative compensation quantity must be specified for
overbatching and a positive correction quantity for underbatching. The permitted input
range is ±10% of the batch quantity. The unit selected in the measuring device is used as the
unit.

Note!
• This module is only evaluated by the measuring device if the additional "batching" software
is installed in the measuring device (order option).
• If the input range is not sufficient for the correction quantity, the batching quantity may
have to be adjusted.
• Further explanation of the parameter FIX COMPENSATION QUANTITY (7204) is
contained in the "Description of Device Functions" manual, which is a separate part of this
Operating Manual.
