This section explains the configuration and optional field cali-
bration for the field inputs of the IMASI23 module (ASI).
Function codes in the controller configure the IMASI23 module
and identify the active analog inputs. These function codes
specify the I/O expander bus address of the ASI module and
the number of active channels on the input module.
Module calibration is performed during module assembly at
the factory. Circuitry and software in the module make auto-
matic adjustments to compensate for application variations,
component drift, and cold junction errors. The ASI module
does provide for field calibration although it should not be
required.
Configure the IMASI23 module by setting the specifications in
FCs 215 and 216 in the controller. One FC 215 is required for
each analog input module and one FC 216 is required for each
channel used on the analog input module. Refer to
for more information on the NTAI06 termination unit.
NOTE: Refer to the Composer Function Code Application Manual for
descriptions of FCs 215, 216, and 217.
The controller initializes the ASI module with the configuration
data specified in FCs 215 and 216. The controller sends a com-
mand to the ASI module whenever new configuration data is
entered in the controller configuration. This command causes
the ASI module to read the configuration data and initialize its
input processing, conversion, and compensation calculations.
FCs 215 and 216 are defined in the controller to configure the
ASI module and identify the active analog inputs. These
function codes specify the I/O expander bus address of the
