1. Introduction
The present Installation Gui e escribes the har ware of the 8DI-4AI-2DO Extension Card -
FLX 3401 of the eWON Flexy family.
The eWON Flexy family is a range of mo ular in ustrial gateway/router.
As the name eWON Flexy suggests, it has been esigne to enable numerous ifferent
combinations of Extension Cards and ase Units. The present Installation Gui e is focusing on
an extension car which, as such, nee s to be inserte in one of the Base Units in or er to work.
The Base Units have their in ivi ual Installation Gui e IG-014-0-EN “eWON Flexy - Base Units”.
The present gui e a resses shortly how the Extension Car s integrate the Base Units an we
give some recommen ations to mount them (see § 3.6 Plugging the Extension Car into the Base
Unit ).
Note: Though being referre to as Digital Outputs, these 2 outputs are actually Normally Open
(NO) relays.

3.6 Plugging the Extension Card into the Base Unit
3.6.1 Base Unit Slot Compatibility
The 8DI-4AI-2DO Extension Card (FLX 3401) can be inserte in all slots of the Base Unit.
Explanation:
The Flexy Base Units feature two type of slots. The A slots are the two first slots starting from the
left. The B slots are the two last slots. Some car s fit in A an B slots. Some not. Car s that fit
only one type of slot have a mechanical mistake-proof security.
The reference co e of the Extension Car s inclu es a letter that efines their compatibility either
with “A” slots, “B” slots or both:
FLA xxxx - esignates car s that fit into “A” slots
FLB xxxx - esignates car s that fit into “B” slots
FLX xxxx - esignates car s that fit into both “A” an “B” slots
In a ition to the car reference, each type of extension car bears a visual compatibility symbol
on its front panel. The visual symbols are shown in the table below:
●●○○ 2 first slots only (A)
●●●● In any slot (X)
○○●● 2 last slots only (B)

Har ware Description Chapter 3.
3.6.2 Extension Car Insertion
Please wait 3 seconds after powering off the equipment before inserting (or removing) an
extension card. This is to avoid possible damage to the Base Unit and Extension Card.
Remove the slot filler of the location where you want to insert the new car . To o this, press on
both en s of the cover, note that the hooks (1) are out-centere like shown on the pictures.
Hooks to be presse are off-centere – press while pulling upwar s
Insert the Extension Car carefully an sli e it own until the hooks are clicking. Make sure the
car is completely inserte .

Har ware Description Chapter 3.
3.6.3 Multiple 8DI-4AI-2DO Extension Car s
The boot process of the Base Unit inclu es an automate etection of the inserte Extension
Car s. This etection is one sequentially, slot per slot starting from the left to right.
The Extension Car s of type FLX 3401 can be inserte in all slots. The eWON Flexy firmware
supports up to 4 Extension Car s of this type.
3.6.4 Basic Principles of the eWON Flexy I/O Tag A resses
The internal tag a ressing of the Flexy range always starts with the Inputs/Outputs of the Base
Units. Remember that all Base Units feature 1 Digital Output an 2 Digital Inputs, those are the
first ones that have to be consi ere when creating tags in the eWON.
The example below helps you to un erstan the syntax of the I/O Server tag a resses in the
case of 2 I/O Extension Car s.
Note: Following the left-to-right order of slots, the first card to be detected is Extension Card
plugged in the most left slot, then the next on its right and so on. Removing an I/O card other than
the utmost right one will result in an internal reallocation of tag addresses that may result in a
mismatch between physical I/Os and their software configuration. The software tag addresses
can be “frozen” by adding the slot number in the tag definition. This prevents accidental I/O
mismatch (see next page).
eWON Flexy - 8DI-4AI-2DO Extension Car - FLX 3401 (Installation Gui e) Page 15/21

Har ware Description Chapter 3.
Slot number appen to prevent tag a ress mismatch:
Let's take the example of an eWON Flexy featuring 2 IO car s FLX 3401 in slots #2 an #4 as
shown in the picture above. The tag a ress for the eWON IO server can be exten e as follows:
ABx,Ey
Where:
●AB is the type of IO (DI, AI, DO)
●x is the or er number
●E is a constant prefix to the slot number
●y is the slot number of the car (0 = main boar , 1 = slot #1, 2 = Slot #2, etc..)
The main IO syntax an or er numbering remains unchange .
In the example above, the IO server tag a resses are as follows:
Tag Syntax Explanation
DO1,EO Digital Output 1, main boar (though E0 is not necessary in this case)
DO2 Digital Output 2, no position specifie = secon etecte DO = first DO on
first extension car etecte (slot #2 most left).
DO3,E2 Digital Output 3, boar in slot #2 = secon DO on extension car in slot #2
DO4,E4 Digital Output 4, boar in slot #4 = first DO on extension car in slot #4
DO5,E4 Digital Output 5, boar in slot #4 = secon DO on extension car in slot #4
Behavior if the car in slot #2 is remove :
In the Tag View page,
●DO2 will appear normally as it was not frozen by a slot number appen . But it can no
longer reflect the status of the first DO of the boar in slot #2 that was remove . DO2 now
reflects the status of the first DO of the boar in slot #4.
●The 3 other DOs with specifie slot number E2 an E4 will all appear in error (re cross,
value 0), because:
a) The a ress of DO3,E2 of the car in slot #2 coul no longer be foun , an
b) The software a resses of DO4,E4 an DO5,E4 of the car in slot #4 o no longer
match with the etecte or er of physical a resses.
The error messages in the Trace log file are “Invali IO Tag name (DOx, a r. DOx,Ex)”.
To have the DOs of the car in slot #4 respon ing, e it the tags an change their software
a resses as follows:
DO4,E4 to DO2,E4 an
DO5,E4 to DO3,E4.

3.6.5 Power Requirements
The internal power converter of the eWON Flexy Base units has been imensione to cover a
broa range of ifferent combinations of Extension Car s. Users shoul make sure the total
power eman of the Extension Car s oes not excee the capabilities of the Base Unit. That is
why the notion of “Energy Points” has been intro uce .
The Installation Gui e IG-014-0-EN “eWON Flexy - Base Units” inclu es a section giving the
Available Energy Points of each type of Base Unit.
The power requirements of each Extension Car is expresse in Energy Demand Points. This
number is meant to check whether the balance with the Available Energy Points of a given
Base Unit with Extension Car s is OK or not.

The Installation Gui e IG-014-0-EN “eWON Flexy - Base Units” inclu es practical examples of
power balance calculations.

4. Po ering On the Base Unit ith its Extension Cards
When the Base Unit is powere on, it takes approximately 25 secon s for the unit to go through its self-
test proce ure. The slots in which the extension car s have been inserte an their type are etecte
uring this process.
If the boot process completes normally, you shoul observe the following LED status

Check Car Detection on the Embe e Web Page Chapter 5.
5. Check Card Detection on the Embedded Web Page
The eWON Flexy Extension Car requires no software configuration. It is automatically etecte by the
Base Unit when it boots.
5.1 Connecting to the Embedded Web Server
Configure the network parameters of your configuration PC to encompass the IP range of the
eWON LAN.
Connect the PC to one of the LAN port of the eWON Flexy.
Open your Internet browser an access the eWON Flexy internal Web page by entering the LAN
IP a ress in the URL fiel (the efault a ress is http://10.0.0.53).
The efault login is: a m
with passwor : a m
Warning!
For security reasons, changing the efault passwor adm is absolutely require .
To change the adm passwor , from the menu bar, click on Configuration, Users Setup an ouble click
on the adm entry to e it its parameters. Enter the new passwor twice an click Save.
5.2 Detected Cards Displayed in the System Page
The etecte car appears in the eWON System har ware configuration page like shown below.
The path to the System har ware configuration page showing the car s etecte by the Base
Unit is: Diagnostic (1) > Status (2) > System Info (3) > System (4). The screen capture below
gives an example of an FLX 3401 extension car that has been etecte in slot 1 (5).
