kivafishy Posted November 6, 2023 Report Posted November 6, 2023 We are going to upgrade mitsubishi PLC from Q series to R series. For existing MNET/H Mode networks, there already have existing PLCs that using QJ71LP21-25. Is there any problem if we use RJ71LP21-25 to connect with QJ71LP21-25? Just to confirm one more thing that the existing optical fiber cables of QJ71LP21-25 can be reused for RJ71LP21-25? I check online they are compatible. Quote
