If you have not yet created a project, proceed as follows:
Start the SIMATIC Manager and create a new project using the guided dialogs via File Assistant
“New project” (assign a project name).
Select the SIMATIC 300-Station . Open the S7 hardware configuration screen by selecting menu com-
mands Edit Open Object .
Open the hardware catalog by selecting Insert Hardware Components or View Catalog . Select
SIMATIC 300 FM-300 FM357-2 (observe the order no.). Drag the FM 357-2 to the slot desired
(in the example: slot 4).
Save and compile your hardware project by selecting commands Station Save and Compile .
The configured CPU and FM 357-2 are now included in your project in the SIMATIC Manager.
Open your project in the SIMATIC Manager.
Select SIMATIC 300-Station CPUxxx S7-Program .
Open library FM357_2L in the SIMATIC Manager with commands File Open... Libraries .
In this library, select S7 directory “BF_V3...”. This directory contains:
a “Symbols” file
a “Sources” directory
a “Blocks” directory
Select the “Symbols” file and copy it to your project under SIMATIC 300-Station CPUxxx S7
Program .
When the message “... Do you want to replace the existing object and all its contents?” is displayed,
click on
Yes .
Open the “Sources” directory and copy the STL source file “fm357ob_n1” (one FM 357-2) to the
“Sources” directory of your project.
Open the “Blocks” directory and copy all the blocks it contains into the “Blocks” directory of your pro-
ject.
Open the copied STL source file “fm357ob_n1” (in “Sources” directory) in your project.
The LAD/STL/CSF editor is started.
Enter the FM 357-2 module address (256 in this example) in the FC 1 call line FMLADDR in OB 100.
Select menu commands File Save and File Compile to generate organization blocks (OB 1,
OB 82, OB 100) from the STL source.
Close the Editor.
Select SIMATIC 300-Station CPUxxx S7 Program Blocks in the SIMATIC Manager. Load
all the S7 blocks (including system data) in this directory to your CPU (CPU must be in STOP state)
by selecting
Target System Load .
Test: Switch the CPU to the RUN state. After a maximum of 60 seconds, the yellow LED “DIAG” on
the FM 357-2 starts to flash cyclically to indicate successful combined power-up of the CPU
and FM 357-2.
For information about programming standard function blocks, please refer to Section 6 of the Manual.
