 Hi Daniel,

Ok. Thank you for information oabout different versions of Step 7. I thought I should adjust Process image partition (red box on picture) because I haven't seen that option in my version Step 7.
The picture I sent is from the example which you linked.

Best regards.

Hello Gujaa;

The DP slave configuration appearsonce you have selected the MS exchanges for your CPU as DP-slave,.

The design of the screen varies depending on the version of Step 7 you are using, but the data you provide is much the same.

See for example step # 6 in the following example, with ios shown in the screenshot below. The screen of this step #6 corresponds to the image you show, even if the design is slightly different.

Hope this helps,

Hello everybody.

Finally, I set correctly hw configurations for master and slave devices. No more red lights on plc after download configurations in master and slave cpu's.
Machine which I need to program is connected to slave device.

Please help.

New question published by Gujaa is split to a separate thread with the subject How can command from code in ladder diagram in FC block send/download to slave and control machine?.
