Mapping
ment operator (i.e. the = sign). For example: i = a + b, means
get the value stored in “a” and add it to the value stored in
“b” and store the sum value at memory address “i”. The left
hand side of the operator sign (=) is the address where you
want the values on the right hand side of the operator sign
(=) to be stored.
Destination - This is the destination memory address to
which data will be moved. Left Hand Side
I/O Interface - The section of the instrument that communi-
cates with the “outside world”.
Input Contact - Inputs interface selector switches, push but-
tons, limit switches and other sensors to the HI 3010. Each
input has an address associated with it which describes the
physical location that the input device is connected to.
Input Image Table - A data table containing addressed
memory where the states of the input devices and parameter
values are stored. The state of each input device is trans-
ferred to the input image table from the input point during
the I/O scan.
Local Mapping - This is mapping within an HI 3010 Filler/
Dispenser module, primarily mapping internal memory loca-
tions of parameter values or device states to locations in the
local Input Image Table or Output Image Table.
Network Mapping - This is mapping between the master
and slave devices in the case of a DeviceNet, ControlNet,
RIO or Profibus network. Hardy Control Link network map-
ping is mapping between nodes on the network.
NOTE: It is important to understand that you cannot per-
form mapping functions on one HI 3000 Series
Instrument from another HI 3000 Series instru-
ment. You must map the memory locations in
each instrument separately. More will said about
this later.
Node Number - This is the physical address of a device in a
network.
Output Relay - Outputs interface indicators, motor starters,
solenoids, and other actuators from the HI 3010. Each output
has an address associated with it. The address describes the
physical location that the output device is connected to.
Output Image Table - The data table containing addressed
memory where the desired state of the output devices and
parameter values are stored. The desired state or parameter
value of each output is transferred from the output image file
to the output point during the I/O scan.
Source - This is the memory address of the data you want to
move to the destination. Right Hand Side
Rules for Hardy Control Link Mapping
Some rules for Hardy Link Mapping:
• Input Contacts (5 total) can only be a
Source.
• Output Relays can be a Source and a Des-
tination.
Local Input
Inputs interface with selector switches, push buttons, limit
switches and other sensors connected to the HI 3010. When
the firmware is initiated it assigns the physical input contact
to a memory address (Remember Inputs can only be a
Source when mapping). (See Source definition in the Glos-
sary of Mapping Terms)
FIG. 6-37 INPUT FUNCTION
• Each input has an address associated with
it.
• The address describes the physical loca-
tion that the input device is connected to.
• The address also describes the Input Image
Table location where the STATE of the
input device is stored.
• The state of each input is transferred to the
Input Image File from the input point dur-
ing the I/O scan every 1/55th of a second.
(See Fig. 6-37)
• When you are mapping an Input to some
other Destination you are assigning the
value in the Input Image Table (for that
Input) to an Address in the Output Image
Table.
• For example: OK TO FILL = Contact
closure input #5 means assign the state
(Open (0) or Closed (1)) of Contact #5,
contained in the Contact Closure input #5
memory address, in the Input Image Table
and move it to the OK TO FILL address in
the Output Image Table. (See Fig. #6-38)
