1.4 Marking of ELX terminals
Name
An ELX terminal has a 15-digit technical designation, composed of
• family key
• type
• software variant
• revision
example family type software variant revision
ELX1052-0000-0000 ELX terminal 1052: two-channel digital input terminal
for NAMUR sensors, Ex i
0000: basic type 0001
ELX9650-0000-0000 ELX terminal 9650: power supply terminal 0000: basic type 0001
Notes
• The elements mentioned above result in the technical designation. ELX1052-0000-0001 is used in
the example below.
• Of these, ELX1052-0000 is the order identifier, commonly called just ELX1052 in the "-0000" revision.
“-0001” is the EtherCAT revision.
• The order identifier is made up of
- family key (ELX)
- type (1052)
- software version (-0000)
• The Revision -0001 shows the technical progress, such as the extension of features with regard to the
EtherCAT communication, and is managed by Beckhoff.
In principle, a device with a higher revision can replace a device with a lower revision, unless specified
otherwise, e.g. in the documentation.
Associated and synonymous with each revision there is usually a description (ESI, EtherCAT Slave
Information) in the form of an XML file, which is available for download from the Beckhoff website.
The revision has been applied to the terminals on the outside, see ELX1052 with date code
3218FMFM, BTN 10000100 and Ex marking.
• The hyphen is omitted in the labeling on the side of the terminal. Example:
Name: ELX1052-0000
Label: ELX1052
0000
• The type, software version and revision are read as decimal numbers, even if they are technically
saved in hexadecimal.
Identification numbers
ELX terminals have two different identification numbers:
• date code (batch number)
• Beckhoff Traceability Number, or BTN for short (as a serial number it clearly identifies each terminal)
Datecode
The date code is an eight-digit number given by Beckhoff and printed on the ELX terminal. The date code
indicates the build version in the delivery state and thus identifies an entire production batch, but does not
distinguish between the terminals in a batch.
Structure of the date code: WWYYFFHH
WW - week of production (calendar week)
YY - year of production
FF - firmware version
HH - hardware version
Foreword
ELX3202 and ELX3204 9Version: 1.2.0
Example with date code: 02180100:
02 - week of production 02
18 - year of production 2018
01 - firmware version 01
00 - hardware version 00
Beckhoff Traceability Number (BTN)
In addition, each ELX terminal has a unique Beckhoff Traceability Number (BTN).
Ex marking
The Ex marking can be found at the top left on the terminal:
II 3 (1) G Ex ec [ia Ga] IIC T4 Gc
II (1) D [Ex ia Da] IIIC
I (M1) [Ex ia Ma] I
IECEx BVS 18.0005X
BVS 18 ATEX E 005 X
