You can map each input channel to one or two analog output channels of
another 972EN or 973EN module. The Map To Holding Register
determines the output channel it will map to. Since the input signal is in
wide-range engineering units, you must also specify the scaling between the
input temperature and 0-100% at the output channel.
Update Time:
Specify a time from 0-90 seconds between messages.
Specify 0 to turn mapped messaging OFF.
Map To IP Address:
This is the Static IP Address of the target output
device (a 972/973EN module on the network).
Map To Holding Register Address:
Specify a valid 4xxxx holding register
address in the target device for writing to the output. For the 972/973EN,
only addresses 40019 to 40024 will apply and correspond to channels 0-5.
Input Scaling:
Since the input signal is in temperature units and wide-
range, you must select which portion of the input range will map to 0% and
100% at the output.

(Optional i2o Function)
The actual data written to the
analog output is rescaled to
percent-of-span units (a 16-bit
signed integer value with
resolution of 0.005%/lsb). .
For example, -100%, 0% &
+100% output will be
represented by the decimal
values
–20000, 0, and 20000,
respectively.
