No GSD file and no special configuration (for example in the SIMATIC Manager) are required for the device.
The telegrams on the PROFIBUS must be known if you want to enter the data to be measured in the configuration files of the device or in ibaPDA. The following signal information must be known:
-
The slave on which it is to be acquired (bus no. and slave no.).
-
If it is a signal that is sent from the DP master to the slave (OUTPUT) or from the slave to the master (INPUT).
-
Where the signal is located in the telegram or where the range of values for several signals starts (byte offset) and what data type is involved. The byte offset is the offset within the payload data.

If you use Step7 and S7-CPUs, you can generate a symbolic address book for the data you want to measure. See chapter Selecting signals via sniffer symbol browser. As a prerequisite, the IO signals have to be defined in the symbol table. |

PROFIsafe PROFIsafe is a certified profile for PROFIBUS and PROFINET which overlays the PROFIBUS and PROFINET standard protocol to transmit safe input and output data. The transmitted data does not only include the pure user data but also an area for the transmission of the data securing information. User data from PROFIsafe connections can be acquired using the same functions as from PROFIBUS and PROFINET standard connections. The definition of the transmitted data can be found in the respective device manual of the IO-module. In most cases, the user data is located from byte offset 0 on. |
