INTRODUCTION EXCEL CARE CONTROL ICONS
74-5577–33 (US) 12
EN2B-0184 GE51 R0518 (Europe)
The two blank rectangles in the dialog box are editing fields where you can enter
values instead of point or icon connections. For example, in the PID dialog box, you
can type an engineering unit table ID and value for the W variable, instead of
connecting W to a point or control icon. For engineering unit, enter the
corresponding index number. Appendix E: Engineering Units in Excel CARE User
Guide 74-5587 (US) / EN2B-0182 (Europe) lists engineering units and their index
numbers.
If a variable does not have editing fields next to it, you cannot type values for a
connection; you must connect it to another icon or a point.

chapter, for procedures to place and connect control icons
Control Icon Table
This chapter lists icons alphabetically by function name and includes function
names, symbols, and short descriptions. Function name is usually the same as the
icon name. There are exceptions such as 2PT which is functionally a Digital Switch.
Function Name
Control Icon
Icon Name
Description
Add
ADD
Sum multiple analog input values (2
through 6).
Analog Switch
SWI
Switch an analog value depending on a
digital value (for example, if digital is 0,
analog is 2; if digital is 1, analog is 1).
Average
AVR
Calculate the average of multiple analog
inputs (2 through 6).
Cascade
CAS
Cascade controller that acts as a PI
controller with a master and cascade
controller.
Cascade (with additional
digital input and
parameter registers)
CAS
Same as previously defined Cascade
controller with the addition of a digital input
and two parameter registers.
Changeover Switch
CHA
Depending on the value of a digital input,
transmit an analog input value by way of
one of two analog outputs.
Cycle
CYC
Establish cyclical operation.
Data Transfer
IDT
Transfer a value from one control icon to
other icons or points.
Digital Switch
2PT
On/off controller that transmits a digital
status depending on two analog values
(one is a controlled variable; the other, a
reference variable).
Duty Cycle
DUC
Switch HVAC systems on and off at
variable intervals to save energy while
maintaining room conditions.
Economizer
ECO
Determine the most economical system
operation for full and partial air
conditioning systems.
Event Counter
EVC
Event counter.
Fixed Applications
XFM
Fixed applications that can combine with
other submodules or points.
