and use these steps to configure high level, or resistance
inputs. Also S4 of FC 216 must be consistent with the type of
calibration being performed.
1. Locate the block address in the controller of FC 217.
2. Verify that the I/O expander bus dipshunts are in place to
allow ASI module bus communications.
3. On the ASI module, for each input channel, place the
jumpers as shown in Figure 3-3.
4. Set S2 of FC 217 to the block address of the FC 215 which
references the ASI module.
5. Insert the ASI module into a powered slot. The green LED
will be solid indicating the module is linked to a FC 215 in the
configuration.
6. Allow the ASI module to warm up for at least 15 minutes.
7. Put the controller in execute mode.
8. Set FC 217 for the required specifications. After each calibration command is issued by performing a tune operation,
monitor the calibration command status to determine if any
errors have occurred during the field calibration.
This example calibrates channel one on the ASI module which
is referenced by the FC 215 at block address 100. For low level
voltage, disable the desired channel by tuning these values
into the specifications.
a. Disable point (S1 = 1).
b. ASI module referenced by FC 215 at block address 100
(S2 = 100).
c. ASI module channel one (S3 = 1).
9. Verify that the low level voltage source is connected to
channel one of the ASI module to be calibrated and the source
voltage is set to the full scale value (+100 millivolt).
NOTE: Each time the source voltage is changed, at least 15 seconds settling
time is required before the point field calibration takes place. If the source itself
has a measurable settling time, add this to the 15 second requirement.

Field Calibration
10. Tune FC 217, specification S5 to the input voltage or resistance value. For this example, tune these specifications:
a. Perform point calibration (S1 = 2).
b. ASI module referenced by FC 215 at block address 100
(S2 = 100).
c. ASI module channel one (S3 = 1).
d. Calibration type zero (low level) (S4 = 0).
e. Calibration parameter 1 - 100 (millivolts) (S5 = 100).
Successful field calibration operations can be verified by
checking for a zero value in FC 217, output N+1 and N+4. If the
point calibration was unsuccessful, an error code will appear
in the FC 217, outputs N+1 and N+4 which can aid in
troubleshooting.
11. Successful field calibration operations can be verified by
checking for a zero value in FC 217, outputs N+1 and N+4 for a
zero value. If the point calibration was unsuccessful, an error
code will appear in the FC 217, outputs N+1 and N+4 which
can aid in troubleshooting.
At this step, two points have been field calibrated (0 and full
scale) and the enable calibration command can be executed.
The three input ranges are low level, high level, or RTD.
If desired, repeat Steps 7 through 10 for channels 2 through 16
to calibrate all 16 channels on the ASI module.
12. Enable the point. Tune the FC 217, specification S1 to
enable the channel. For this example, tune these
specifications:
a. Enable the channel (S1 = 3).
b. ASI module referenced by FC 215 at block address 100
(S2=100).
c. ASI module channel one (S3 = 1).
d. Calibration type x (S4 = x). x is a do not care value.
e. Calibration parameter x (S5 = x).

A successful enable operation can be verified by checking FC
217, outputs N+1 and N+4 for a zero value. If the enable was
unsuccessful, an error code will appear in the FC 217, outputs
N+1 and N+4 which can aid in troubleshooting.

Operating Procedures Section 5
Introduction
This section explains the startup and operation of the IMASI23
module (ASI).
Startup
Communication between the ASI module and controller starts
when the two modules are configured correctly (refer to
Section 4). The ASI module address in FCs 215 and 216 must
be the same as the address set on the address dipswitch.
Upon startup, when power is applied to the ASI module and
the controller is put into execute mode, all channels are initially marked bad quality until the controller downloads the
configuration data and the ASI module processes a valid input
signal.
Operation
The controller sends an interrupt command to the ASI module
whenever it sends new configuration data. This interrupt
causes the ASI module to read the configuration data and initialize its input handling, conversion, and compensation calculations. Once configured by the controller, the ASI module
scans its inputs and makes corrected values available to the
controller over the I/O expander bus. The controller reads the
values from the ASI module during its normal segment cycle
operations. Refer to Section 2 for more in
