Dear Guileser, I'm sorry but you should replace your module (422-1BL00-0AA0) with (422-7BL00-0AB0). The point is that you can't configure the 1BL00 module as a redundant module inHW configuration. When you configure redundant modules in HW configuration. The SIMATIC Manager creates data blocks for redundant I/Os. Then you use some FBs and FCs to handle redundant I/Os in your user program. I never tried to construct redundant I/O's using modules that are not listed in the link you saw. I don't understand the criteria that Siemens used to give us such a list of redundant modules. If you can't buy the 422-7BL00 you can try the 1BL00 and program the redundant digital outputs yourself. I'm not sure but it might work. just study the issue carefully and write your code and test it on the hardware you have for the time being. If you can't make it then just buy the 7BL00. Take care of the diodes issue. Best regards. H-H Attachment400H3.pdf (198 Downloads) |
