HelloRAJKIRAN, Open SIMATIC Manager and open the sample projects instead of user projects. you will find 2 projects, ZXX01_14_HSystem_S7400H for basic hardware configuration. ZXX01_15_HSystem_RED_IO for redundant I/Os configuration and programming. Best regards. H-H

HelloRAJKIRAN, Are you sure you have put your user program between FB450 and FB451? Please upload your diagnostic buffer and definitely it will be better if you upload your sample project here for better investigation. I also recommend to reassign the I/O modules to a process image partition that's updated with a cyclic interrupt and write all your code in this cyclic interrupt. Best regards. H-H |

HelloRAJKIRAN In hardware configuration, CPU properties, H parameters then redundant I/O data blocks are 1 & 2. You can't use DB1 and DB2 in your project. You have to change either DB1&DB2 in your program or change the redundant I/O data block in HW configuration. You have assigned your I/O modules to PIP1 which is updated with OB35. So, remove all networks in OB1 except network one (Report System Error). Write you program in OB35 between FB450 and FB451. Also, you don't need to call FB450 and FB451 in OB10. Best regards. H-H
