SECTION 4 - CONFIGURATION AND CALIBRATION
INTRODUCTION
This section explains the configuration and optional field cali-
bration for the field inputs of the Universal Analog Input Slave
Module (IMASI03).
Function codes in the master MFP configure the IMASI03 and
identify the active analog inputs. These function codes specify
the slave expander bus address of the IMASI03 module and the
number of active channels on the slave module. The type of
input, and the zero and span in engineering units, is also spec-
ified by the user with a function code. Set function code 215
and 216 in the master MFP to configure the slave. Refer to
for descriptions of function code 215, 216 and 217.
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 slave does pro-
vide for field calibration although it should not be required.
CONFIGURING INPUTS
Configure the IMASI03 by setting the specifications in function
code 215 and 216 in the master MFP. One function code 215 is
required for each slave and one function code 216 is required
for each channel used on the slave. Refer to
for
more information on the termination module NIAI05 and
for more information on the termination unit
NTAI06.
CONFIGURING FUNCTION CODES
The MFP initializes the IMASI03 slave module with the configu-
ration data specified in function codes 215 and 216. The MFP
sends a command to the IMASI03 whenever new configuration
data is entered in the MFP. This command causes the slave to
read the configuration data and initialize its input processing,
conversion, and compensation calculations.

Function Code Application Man-
ual
, I-E96-200, for more information on function codes 215
and 216.
Function codes 215 and 216 are entered in the master MFP to
configure the IMASI03 and identify the active analog inputs.
These function codes specify the slave expander bus address of
the IMASI03 module as well as the channel number on the
