1. The I/O mapping display will show all inputs at the selected module - both physical inputs and
internal inputs. Select the input to be mapped.
2. If you wish to invert the mapping, select the “Invert Input” box. If you invert an input, then the
output will be the reverse of the input. Analog I/O can also be reversed - 0mA will be 24mA,
4mA will be 20mA etc. Do not invert pulse inputs.
3. The invert function is not available on -2 modules - only inverted digital inputs are available (as
internal inputs on the input list).
4. To select the destination module, you can either select the module from the “Destination Unit” list,
or enter the unit address in the “To Destination” box. You can enter an address that has not yet
been allocated to another unit.
5. You can select the output by entering the output number (1 – 8) in the “output” box, or select an
output from the displayed list. There will only be a list of possible outputs displayed if at step 2 you
selected a desrtination until that has already been configured in the system. The output numbering
for each module is:
105-1 105-2 105-3
First addr
(Even)
105-3
Second addr
(Odd)
105-4

Output 7 PO None DO 7 AO 7 DIO 3 DIO 11
Output 8 None None DO 8 AO 8 DIO 4 DIO 12
6. If you select a 905U-C as the destination module, you will be asked to select a I/O Register as the
destination “output”. Note that the grey-shaded I/O registers have already been allocated.
7. Select any intermediate repeater units needed to reach the destination address (entered in order of
nearest to furthermost repeater). You can either select from the list of configured units or enter the
unit address in the “Repeater” box. If no repeaters are required, do not enter anything in the
repeater boxes. If only one repeater address is required, enter the address in box 1 and leave the
other repeater boxes empty.
It is possible to configure multiple mappings for an input - each mapping will generate separate
transmissions. We recommend that you do not configure multiple mappings to the same output as the
output will have the value of the last message that it receives. Each output should have only one
mapped input.
