Figure 3-8
shows a simplified representation of mapping. A 4-20 mA
analog input is connected to the NETio Wireless Expansion Module (on
the left) with a Module ID of 0. This input is mapped to a 4-20 mA
analog output connected to the NETio Expansion Module with a
Module ID of 1(on the right).
To configure the mapping, enter the address of the Analog Input (in this
example,
0
,
AI 1
) in the
Source
field for the Analog Output (in this
example,
1
,
AO
1
).

Figure 3-8. I/O Mapping Overview
I/O signals can be mapped between NETio Modules that share the same
WeXP Network Address and/or NETio-TB Base Module. The only lim-
itation is than an input can only map to an output of the same type
(analog-to-analog and discrete-to-discrete).
3.4.1 Setting the Source Field for Mapping
Mapping is accomplished simply by setting the address of the input
point signal into the source field in an output point.
Figure 3-9
shows the Analog Output Menu with the source field set to
3,
AI 1
. This means that this Analog Output will regenerate the signal con-
nected to AI 1 in Module ID 3.
