Smart Distributed System (SDS) protocol was developed by
Honeywell and is supported by
Holjeron. SDS is an open
event-driven protocol used over
Controller area network based industrial networks. It is used for a highly reliable
Smart device-level network. The SDS Application Layer Protocol is optimized for
smart sensors and actuators, where
configuration, diagnostic, and
process information can be embedded cost-effectively in a very small
footprint.

kbit/s (longer with Bridge).
Can support 64 maximum electrical loads (Nodes) per network without
repeater & 126 with repeater.
