Step7 - Classic - W.E.ST. POS-124-U-PFN Technical Documentation Manual

11.2 STEP7 – classic
If controllers of the S7-300/-400 series are used, their programming can alternatively be done using the "Si-
matic Manager".
First the GSDML – file has to be imported in the HW – configurator.
Then create a Profinet – system and choose the component „UNIGATE IC-Profinet 2Port" from the catalogue
folder "PROFINET IO / Additional Field Devices" and add it to the Profinet-IO-System.
Then you can open up the device in the right window and take the element „IN/OUT: 32 bytes" from the "bidi-
rectional" subfolder and place it in the slot 1 of the device (window left / bottom).
The system will automatically assign addresses (I address / Q address).
These may be altered if required. The start addresses of both ranges need to be kept in mind because they
have to be entered as fix input parameters for the driver block.
As driver we supply a STL source (*.awl) which can be imported into the "Sources" folder:
The source contains a symbolic name for the blocks which corresponds to the file name, here it is
„WEST_POS124U_PFN".
Prior to compiling them, a free block number has to be allotted to the name in the Symbol Editor:
