Replacement & Compatibility FAQ
Q: Can I replace 1783-BMS06SA with 1783-BMS06SA2?
A: Yes, the Gen 2 variant is a functional drop-in replacement with the same port count and IOS base. Verify firmware version compatibility in Studio 5000.
Q: Is the 1783-BMS06SA compatible with non-Rockwell PLCs?
A: Yes. As a standard managed switch with Cisco IOS, it can operate in any EtherNet/IP or standard TCP/IP network, though Studio 5000 integration features will not be available.
Q: What is the difference between BMS06SA and BMS06SGA?
A: The BMS06SGA adds one SFP fiber uplink port, enabling longer-distance or electrically isolated backbone connections. All other specifications are identical.
Q: Do you offer warranty on surplus units?
A: Yes, Konmask provides a 90-day functional warranty on all verified surplus units. Extended warranty available on request.
