Step 8. Click on “DeviceNet Boolean In” or “DeviceNet
Int In” to select it as the Source for the Assignment
Statement. (See Fig. 6-31)
Step 9. Click in the Word text box and type in the number
“2”.
Step 10. Click on the Select button to save the source.

FIG. 6-32 ASSIGNMENT STATEMENT MAPPING
DEVICENET INT IN (DIO2) TO OUTPUT RELAY #2

Step 12. Now whatever is sent to DeviceNet Boolean In
(DI2.1) or Devicenet Int In (DIO2) from the Net-
work will be sent to Output Relay #2.

More Advanced Mapping
This section is for those who have some or a lot of experi-
ence Addressing I/O (mapping) or for those who want more
information as to how the mapping works locally and on the
network. We go into much more detail as to how the map-
ping works and include instructions for Boolean, Analog,
Mixed and Special Command mapping procedures.
Mapping is similar to Addressing I/O’s in a PLC except there
are no predefined mappings in the HI 3000 Series Instru-
ments and you are not mapping the physical location of an I/
O module terminal to a bit location in the processor, you are
actually mapping values or states in memory to another
memory location. This difference is important to understand
and will be explained later in this chapter. In order to under-
stand Mapping we first need to define some of the terms and
understand the structure of an Assignment Statement.
In short mapping is nothing more than assigning data from
an address (Source) to another address (Destination) to be
used by the controller in ways that meet your process
requirements. Since the HI 3010 does not have any pre-
defined Addressed I/O you are free to Address I/O in any
fashion that meets your needs.

Assignment Statement - The assignment statement is an
order to the computer to change the value stored in the vari-
