Depending upon what type of input you selected, the 

Analog Input or the Digital Input screen will appear. The 
analog screen is described in Section 9.1.3.3, while the 
digital screen is described in Section 9.1.3.4.

In order for the E2 to properly read an input value from 

a sensor or transducer hooked to an I/O board, you must 
first tell the E2 what kinds of devices are hooked into each 
input board point. This is achieved by using the Input 
Definitions/Status screen. 

 (SETUP),  (DEL/

MOD), 

 (OFFSET),  (LOOK UP), and  

(CANCEL) are the function keys along the bottom of the 
screen available for the Input Definitions/Status screen.

Each record in this screen contains the following infor-

mation about a point:
1. Type (read-only)

The Type column will read 16AI regardless of whether 

the input board is a 16AI, MultiFlex 16, 8IO, or MultiFlex 
Combination I/O board. 

 2. Board (read-only)

The point’s board number will appear in its point 

record under the Board column. All input boards on a 
controller will be displayed.
3. Point (read-only)

The point number of each point appears in its record 

under the Point column.

4. Type (read-only)

The Type field shows the output’s data type. Possible 

Types are: A (Analog) or D (Digital). If the point has not 
been identified, a “-” will appear in the field instead.
5. Application

 Select which application you wish to set up inputs to. 

Pressing 

 (LOOK UP) when on a defined point will 

open the Application Selection menu--a list of application 
types currently existing in the box. 

 (CANCEL) will 

cancel this menu.
6. Association

If a point has already been defined and is currently 

being used by an application, the name of the input to 
which the point is connected will be displayed in the Asso-
ciation field.

Association is the application’s user-defined property 

that is associated with the point. Multiple applications 
attached to single input will all be displayed in the Associ-
ation field. Pressing 

 (LOOK UP) on a set applica-

tion will bring up a list of property selections. 

 

(CANCEL) will cancel this menu.
7. Value (read-only)

Value shows the sensor value in the units you select for 

the input type.

Open the Analog Input screen by selecting an Analog 

(A) input from the Input Status screen Figure 9-4 and 
pressing 

 (SETUP).

The Analog Input screen Figure 9-4 is where sensor 

types, units, and default values are specified for analog 
input points.
