Loading the user program
When commissioning the ET 200S, you can download the user program to the
IM 151-7 CPU in the following ways:
The program is downloaded from the PD/PC to the memory module (MMC)
inserted in the IM 151-7 CPU by means of the ”Load User Program” function.
Note
This function does not delete retentive areas.
The program is transferred from the PD/PC to the memory module (MMC). The
memory module is then inserted in the IM 151-7 CPU and the memory reset
request acknowledged.
See Section 8.3.
Tip: Programming OB 82 and 86 during commissioning
Always program OB 82 and OB 86 when commissioning as an I slave in the DP
master and I slave using STEP 7. This will allow you to detect and evaluate the
operating states of and interruptions during user data transfer (see Tables 7-6 and
7-7).
Note
Without configuration, a default start-up is possible if the power modules are
switched on and all the modules are inserted.
Start-up
When the IM 151-7 CPU is switched to RUN mode, the following mutually
independent operating mode transitions take place:
The CPU switches from STOP to RUN mode.
The IM 151-7 CPU starts user data transfer with the DP master on the
PROFIBUS-DP.
When the DP master module is plugged in, the IM 151-7 CPU starts user data
transfer with the DP slaves on the PROFIBUS-DP.
