LON Software Interface Description
Overview
LonTalk Protocol
LION LONWORKS Bus I/O Modules use a LONTALK protocol
communication with other nodes on the L
ONWORKS network,
with commissioning tools und supervisory devices.
Features
• Network variables for communications between nodes,
but no explicit messages
• Configuration network variables
• LONMARK FPT protocol for downloading a LION
L
ONWORKS Bus I/O Module firmware via LONWORKS:
loadable apbG file (supported by CARE and EXCELON)
Addressing, binding, and commissioning
LION LONWORKS Bus I/O Modules are addressed, bound,
and commissioned using CARE or any other standard
L
ONWORKS commissioning tool based on LNS 2.0 and
higher, e.g., LonMaker for Windows.
Configuration
LION LONWORKS Bus I/O Modules are configured using
CARE or COACH.
CLIOL821A Analog Input Module
For the CLIOL821A Analog Input Module the LONMARK
Profile 520 "Analog Input" has been assigned per input.
Each input object has its own configuration properties,
except for heartbeat configuration, which will be shared
among all objects.

Transmission/Updates
These variables are transmitted immediately when their
value has been changed by a higher rate than the
configured "send on delta" (default: 0.3 K).
These variables are also transmitted as heartbeat output
(default: 60 sec) on a regular basis as dictated by the
maximum send time (nciSndHrtBt) configuration variable.
