FUNCTION CODE DEFINITIONS
ENHANCED CALIBRATION COMMAND FUNCTION CODE (FC 217)
I-E96-301B
C - 13
6 - Reset user gain and offset adjustment
. This command
cancels any previously entered user gain and offset adjustment
for the specified channel.
7 - Display uncorrected point data
(percent of positive full
scale). This command performs no operation other than to
update the uncorrected output data value for the specified
input channel (block output N of function code 217).
8 - Update point data
. This command causes a new scan of
the specified input channel to be performed and the output
data value of the block to be updated with the new uncorrected
value.
9 - Slave escape command
. Performs Point Escape command
to all 16 channels and cold junction reference on the IMASI03
slave module.
10 - Expander bus test command
. Performs single test of
expander bus between MFP and slave. The test verifies trans-
mission, reception and data integrity of messages passed
between these modules. (Intended as an additional diagnostic
for the slave interface. It requires an MFP.)
11 - Restore factory calibration command
. This command
overwrites the field calibration data in NVRAM with the original
factory calibration parameters. This command resets the val-
ues entered in the set user gain and offset command.
S2
This specification identifies the block address of the enhanced
analog slave definition (function code 215) function block iden-
tifying the slave module to which the command specified in S1
is to be applied.
NOTE: For MFP01/02 firmware releases prior to C_0, S2 identifies
the
expander bus address of the slave module to which the com-
mand specified in S1 is to be applied.
S3
This specification identifies the slave input channel number to
which the command specified in S1 is to be applied.
S4
This specification identifies which type of calibration is to be
performed.
0
=
Low-level (millivolt, thermocouple)
1
=
High-level
2
=
RTD
S5
This specification is used for channel calibration and changing
the user gain and offset value. Calibration parameter 1 pro-
vides a real value dependent upon the type of command speci-
fied in S1.
