S7-400 Redundant fault (Cement industry) I have encountered the S7-400's,which is placed in the server room,(air con. temperature: 19 C, clean room) problem. The slave doesn't work and shows redundant fault even I've changed its to match with another master. Thus, I have some questions to ask: 1. What is the main cause of S7-400 Redundant fault? 2. How to prevent my S7-400 from this problem? However, I've changed the PLC to the new one but I don't want to change it every time I have this problem so do you have any comment on how to fix this.
