For measurement data acquisition with ibaPDA-Request-S7-DP/PN/ibaNet-E the measurement data is actively transmitted from the controller to ibaPDA via PROFIBUS slaves or PROFINET devices implemented in the device used (e.g. ibaBM-DP) or using the ibaNet-E (UDP) protocol. For this purpose, one or more Request blocks (FB/FC + DBs) have to be integrated for each slave/device/connection in the S7-CPU program. These Request blocks are used to send the S7 operands/symbols selected by the user within ibaPDA to ibaPDA. If the signal selection is changed, no changes to the S7 program are needed.
You can select the signals to be measured either using the absolute operand address or using the symbolic name with support from the ibaPDA address book browser. This browser allows access to all defined symbols in the connected STEP 7 project.
For S7-1500 you can use optimized data blocks. Signals within these data blocks can only be accessed using their symbolic names and not using the address or the operand. For CPUs with firmware V3 or higher, it is also possible to access this data using special Request blocks.
