Integration in the user program
1. Create the OB 1 user program in the LAD/STL/FBD editor.
Example 1: Reading an input and controlling an output:
STL Explanation
A I 0.0
A M 2.0
S Q 0.0
If input bit 0.0 and
memory bit 2.0 are set, then
set output bit 0.0
Example 2: Transferring an input byte to an output byte:
STL Explanation
L PIB 0
T PQB 0
Load I/O byte 0 in the accumulator (bits 0.0
to 0.7)
Transfer the contents of the accumulator to
I/O output byte 0 (bits 0.0 to 0.7)
2. Save the project in SIMATIC Manager.
3. Load the configuration in the DP master.
Switching on
1. Switch on all the power supplies of the ET 200S.
2. Watch the status LEDs on the DP master and ET 200S.
