A.O. Smith AIN Slave
A.O. Smith AIN (Advanced Internal Network) Slave can be configured on the RS-
485 port by selecting
AO Smith AIN Slave
from the protocol dropdown menu.
The AIN Slave protocol uses service objects to define desired parameters from
the master to capture the values for and to write to. For more information on
service objects, refer to section 8.5. Each parameter in a service object is
mapped to 2 bytes in the database (the data size is fixed at 16-bit, as this is the
native data size of AIN parameters). For more information on parameter
mapping, refer to section 11.1.2.
