6.2.5 Reading/writing data records
Introduction
Every data record (DR) can only be read fully from the electronic weighing system to the
SIMATIC controller or written to the electronic weighing system. Transfer of a single parameter
within a data record is not possible.
Data in the "cyclicIoData" structure is updated automatically without commands via cyclic
communication.
Requirements
You have called the FB (Page 41).
Example: Reading and writing DR07
CAUTION
The number of system functions that can be called at the same time is limited.
Start the commands for reading and writing a data record only when necessary.
