S7 5.5 SP2 HF4 K5.5.2.4 CFC V7.0 SP1 7.0.1.0 ESD & F&G sytem using S7-412H with ET200M remote IO Interface via Simatic NET OPC Server to 3d party SCADA Ok, so I am working with CFC for a while now, I can get all the basics going but I am stuck however with a few issues that some knowledgeable people might be able to help me with. [schnippschnapp] 2) When setting up communications wiht my SCADA I am interfacing directly with the safety DB's via OPC. As a test I wrote a value to the safety system (assuming / hoping it would be rejected). The system went into F-stop. a tricky question here, but can I stop the system from doing this? at least for the Fire and Gas system. When an F-stop happens my plant is no longer protected / monitored for gas releases etc. which is a very bad situation to be in. The manual states I can create various F-shutdown groups, and only one group will be shutdown on detection of an error. Is it true that this will only work if the IO is segregated? right now my ESD and F&G IO are mixed over the cards for availability reasons. [schnippschnapp] other questions can be found in the following thread CFC F-system, standard MOS block CFC F-system, Chart IO CFC F-system, Code versions CFC F-system, CPU system status CFC F-system, sometimes when I place CFC blocks on the screen they are assigned different number these are the main things I am running into, any help would be greatly appreciated |
