Protocol-Specific Information
This section will discuss topics that are specific to each of the supported
protocols.
11.1
A.O. Smith AIN Slave
11.1.1
Overview
The gateway supports the A.O. Smith Advanced Internal Network (AIN) slave
protocol on its RS-485 port. Some notes of interest are:
•
Supports both commercial and residential A.O. Smith gas and electric
products.
•
A range of master parameters in one block may be read or written by
configuring a single service object.
•
May be connected along with other modules on the network including local
and remote displays and other interface devices.
11.1.2
AIN Service Objects
The AIN slave driver uses service objects to describe what services the gateway
should perform. Each service object can access a range of parameters located in
one block on the master device. To read data, when enabled, the gateway will
compare the parameters in the block broadcasted by the master and store any
matching parameter values into the database. When data in the database
changes where a service object is mapped, the gateway will generate a write
command to the master device for that service object attempting to write the
value, when enabled. For more information on configuring AIN service objects,
refer to section 8.8.1.2.
