To adjust input and output properties
An input or output must be assigned to its corresponding point in the control program. This is typically
done when the control program is created, but you can adjust the settings at the time of installation in
the WebCTRL® interface.
1 In the WebCTRL® Geographic tree, select the equipment controlled by the FIO expander.
2 On the Properties page, select the I/O Points tab.
3 For each point, type the expander's rotary switch address in the Exp field and the number of the
expander's corresponding input or output in the
Num field.
EXAMPLE If UO-01 on the FIO expander (which has a rotary switch address of 5) is used for the
point
Fan S/S, enter 5:1 in the Exp:Num column for Fan S/S.
NOTE Do not assign the same output number to more than one point.
4 Enter the appropriate values for each input and output in the remaining columns. See Input values,
Output values, Resolution values and Offset/Polarity values below.
CAUTION Do not assign two input microblocks to the same physical input using Dry Contact in
one and Binary Input in the other. This results in faulty behavior.
5 If you have not performed the initial download to the attached controller, you must download now
to verify inputs and outputs.
6 To verify each input's operation, force each sensor to a known value, then compare it to the Value
shown on the
Properties page on the I/O Points tab.
7 To verify each output's operation, lock each output to a known condition on the I/O Points tab, then
verify that the equipment operates correctly.
See Troubleshooting inputs and outputs (page 24).
