Hello everyone.... Please help me solve the following problem I'm trying to establish master -slave communication between these two PLCs for a week now. And it doesn't work. When S7-315-2DP is master after I switch it to RUN it shows sytem error and goes to STOP mode. I have the same problem when S7-315-2DP is slave. I've attached few screen shots of a Diagnostic buffer in both cases and hope that you can help me out. Best regards AttachmentScreen_shots.zip (709 Downloads) |

Hi people! I didn't think you would reply me so fast Thanks for helping! Here goes more information about my problem.... The error occurred when OB82,OB85,OB86, OB87, OB121, OB122 and of course OB1 were included in master's (315-2DP) and slave's (313C-2DP) program. Yesterday after I've put the post I tried to establish communication between 316-2DP (master) and 313C-2DP(slave) and 316-2DP did the same thing as 315-2DP in previous case. After I switched it into RUN mode it went into STOP mode and the same system error was shown : STOP caused by parameter assignment error or unpermissible between preset and actual configuration. The whole time 313C-2DP (slave in both cases) stayed into RUN mode and system error lamp lighted. I've attached project so take a look. Best regards, zara Attachmentzad02_06.zip (534 Downloads) |
