Note!
The control (e.g. switching on positive zero return) is executed by cyclic data transmission if the
output byte
switches from “0” to the bit pattern in question. The output byte must always switch from “0”. A
switchback to “0” does not have any effect.
Example (change the output byte)
Output data
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!
!
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.
