Re: FBM 232/233 (ethernet) are designed not to work in multidrop

Shaun, would you elaborate on this? I don't understand what you are
saying.
The Ethernet version of FDSI FBM supports up to 64 devices on an
Ethernet network; your mileage may vary based on protocol. Each device
does require its own IP address which is the norm on an IP network.

Hi Virgil
FBM 232/233 (ethernet) are designed not to work in multidrop situations
Even though they use IP address and device address in their
configuration they insist on only one device per IP address.
In my situation I wanted to talk RS485 to Durag flame controllers and
had to install an IP/Serial gateway per Durag
