Hi We had a problem with flash memory on s7-414-4h station, When go online in cfc editor and enable watch on/add io to monitor block i/o s, got the error code 254:61046 "io v on block input can not be watched" The system had been working well before. Nothing solve the problem such as factory reset, retriving certified backup,system image recovery.... upgrading pcs7 v7.1sp2 to v8.0sp2 did not solve the problem too. That time i read topic (CFC - Cannot add parameters to the watch list) like my problem which solved by downloading all blocks to plcsim and then to real plc flash memory( because of time stamp issues). As my hardware was h system so i can not download to plcsim ofcourse. At last i exchanged flash memories with the ram memories of another plant project.( because of operational priority i must startup the other plant and so could n't use ram for time stamp correction ) Two stations have been working fine till now, but is n't really any untricky solution for this issue? Regards hosein P.s: dear moderator please lock the other topic split from CFC - Cannot add parameters to the watch list Thanks. |
