Greetings to all Simatic users! I recently came across a problem that I cannot still solve. This is the HW printscreen of the plant (Pic1) The CPU 414-3 DP is powerful enough to address all the slaves which are present in the two Profibus segments (Pic2)When I simply inserted a new analog input module into ET200S (station 1), assigned start input address 548 to the module (as it had been prompted automatically by a system ), recompiled everything and loaded into CPU, I discovered that the station 2 (pic 3), belonging to the same Profibus segment (Pic3 - station 2 IO field), became inaccessible! Errors are shown in the diagnostic buffer (pic.5, 6) I tried assigning the start address 900 to the 2AI module, choosing image table PIP1 instead of OB1 (in the properties tab of the module). Everything failed!! Station 2 got accessible again after I had deleted the module from the HW and dismantled it physically from the cabinet. Every help is appreciated!!
