hi dears I have trouble connecting to PLC S7 313C. This PLC has only one MPI port. Unfortunately this port is broken and I can not connect to the device. I use the USB PC ADAPTOR to connect. pc adaptor Checked with another PLCs and is correct. baud rate and address is correct too (0 30 187.5 31) I even changed the ic transiver 65176b of the intrface board, but it didn't work. The plc is in normal status and can be runed and stopped, only it is disconnected from the outside. What do you think is the reason for this problem? local MPI addressfor the programming device/PC is higher than the maximum nodeaddressor wrong transmission rate or wrong interrupt set ------------------------------------------------------------------------------------------ |

Hello Vivid; Have a look at RatedX's suggestions in this thread, and try them out: https://support.industry.siemens.com/tf//ww/en/posts/mpi-port-trouble/90079?page=0&pageSize=10 If these diagnostics do not help, consider your MPI port as defective, contact Siemens for a repair if you have no other choice of PLC to control your process. Open the Services link at the top of this page, look for Repar Services, then Standard Repairs for the Repairs contact link. Hope this helps, Daniel Chartier |
