Can someone please help me. I'm trying to get a Siemens HMI to communicate to an Allen Bradley 1400 Micrologix build is a 1766 series B. What cable do I need to communicate. I know the Siemens side (WinCC Flex). The micrologix has a db9 (232) port, a 8pin mini, and an ethernet port. I know the HMI will do RS422, RS485. What port do I use on the Allen Bradley side and what setup (DF1 or DH485) Any help would be appreciated.
Thanks,
Adam
