Hello TO-220, in the manual PCS 7 Help on CFC - Elementary blocks at section IK_ALARM I found follow information: The IK_ALARM block is part of the runtime system to support the AS-wide interconnections; it is copied during initial creation of an AS-wide interconnection to the block folder of the S7 program. So please check how many AS-wide interconnection you have. With regards |

Thank you for a link to that manual! I've also grabbed a copy of the manual referenced in the section you mentioned. CFC for Simatic S7 The number of connections does not seem unreasonable. In communicating with around 5 other controllers there are less than 8 connections when going online. I tried deleting all the profibus and ethernet connections for the afflicted controller, compiling then re-adding those connections. But that did not seem to help any. These overload sender alarms are over running our alarm and journal screens. I hate to just disable the message, something is going on. I may try replacing the controller just to rule out any hardware issue. Any thoughts would be greatly appreciated! : ) |

Hello TO-220, I found only two relevant sections about the AS-wide interconnections in official Siemens documents :
I hope that the documents can help you. With regards |
