Emerson E2 Manuel D’Utilisation

Depending upon what type of output you selected, the 

Digital Output, (see Section 9.2.7.3, Setting Up Digital 
Outputs) Pulse Digital Output, or One Shot Digital Output 
screen will appear.

The Output Definitions/Status screen serves a dual 

purpose. It is both an at-a-glance summary of all points on 
each output board and a menu where output points may be 
selected and configured.

In order for the E2 to properly control devices that are 

hooked to an I/O board, you must first tell the E2 what 
type of output the devices require. This is achieved by 
using the Output Definitions/Status screen.

 (SETUP),  (DEL/MOD),  (LOOK 

UP), and 

 (CANCEL) are the function keys along the 

bottom of the screen available for the Output Definitions/
Status screen.

The Output Definitions/Status screen serves a dual 

purpose. It is both an at-a-glance summary of all points on 
each output board and a menu where output points may be 
selected and configured.

Each record in this screen contains the following infor-

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

Board Type shows which kind of output board the 

point is on. The Board Type field will read either 8RO, 
8DO, or 4AO for I/O Network 16AI boards, E16AI, and 
8ROE for Echelon Network 16AIe boards.

The last character of the Board Type field also shows 

what type of input the point is defined as. If a point has 
already been defined as an analog or digital input, this 
field will signify its input type with an “A” (for analog) or 
“D” (for digital).
2. Board (read-only)

The point’s board number appears under the Board 

field.

3. Point (read-only)

The point number of each point appears in its record in 

the Point field.
4. Type (read-only)

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

Types are: A (Analog), D (Digital), O (One Shot), or P 
(Pulse). If the point has not been identified, a “-” will 
appear at the end of 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) when on a set 

application 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 output type.

Open the Digital Output screen by selecting a Digital 

(D) input from the Output Status screen Figure 9-10 and 
pressing 

 (SETUP).

Digital Outputs are ON when the E2 calls for them to 

be ON, and OFF whenever the E2 calls for them to be 
OFF. Most outputs that directly activate and deactivate 
output devices will need to be set up as the Digital output 
type.
