To use an input or output, you must assign it to its corresponding point in the control
program.
1
In WebCTRL's
GEO
tree, select the equipment controlled by the Room Controller.
2
On the
Properties
page, select the
I/O Points
tab.
3
In each point's
Num
field, type the number of the controller's corresponding input or
output. For example, if you use DO1 on the Room Controller for the point
Fan S/S
,
type
1
in the
Num
field for
Fan S/S
.
NOTES
○
Exp
(expander number) is 00 for the Room Controller.
○
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.
NOTE
You can also enter these values in EIKON LogicBuilder.
5
If you have not performed the initial download to the Room Controller, you must
download now so you can 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.

The sensor reads a value and sends a corresponding signal (Volt, mA, or psi) to the Room
Controller's physical input. The Analog Input microblock uses the Min
and Max
values to linearly
translate the signal into the engineering value used in subsequent control logic. For example, set
Min to 0 and Max to 10 for a 4–20 mA sensor that measures velocity from 0.0 to 10.0
inches/second so that when the input reads 4 mA, the microblock outputs a value of 0. Similarly,
when the input reads 8 mA, the microblock outputs a value of 2.5.

You can set up a
custom translation table
(page 22) on the driver's
Custom Translation Tables
pages in WebCTRL.
3
The control program must have one Pulse to Analog Input microblock for each pulse counting input.
