If desired, repeat Steps 7 through 12 for channels 2 through 16
to calibrate all 16 channels on the slave.
14. Enable the point. Tune the FC 217 block specification 1 to
enable the channel. For this example, tune these
specifications:
a. enable the channel
S1 = 3
b. the slave referenced by FC 215
S2 = 100
at block address 100
c.
slave channel 1
S3 = 1
d. calibration type x
S4 = x
1
e.
calibration parameter x
S5 = x
A successful enable operation can be verified by checking FC
217 blocks N+1 and N+4 for a zero value. If the enable was
unsuccessful, an error code will appear in the FC 217 blocks
N+1 and N+4 which can aid in troubleshooting.
A channel can be calibrated over the range used, even if it is
only part of the total range of the sensing device. For example,
If the range of channel 1 was -100 mV to 0.0 mV enter -100
mV, -90 mV, -80 mV (10 mV increments) up to 0.0 mV. Or if
the range of channel 1 is -100 mV to -90 mV enter -100 mV,
-99 mV, -98 mV, (1 mV increments) up to -90 mV.
This provides very accurate values from the slave to the MFP
for the range of the sensing device used (-100 mV to 0.0 mV,
-100 mV to -90 mV).
1. x is a do not care value.
