2) Introduction
2.1 Introduction
This document describes the use of a 4X50 Ethernet system unit from Eilersen
Electric. The 4X50 system unit consists internally of a 4050 Ethernet module
(with the software listed on the front page) and a 4040 communication mod-
ule.
The 4X50system unit is connected to X loadcells (1-4). With the program
specified on the front page, the 4X50 Ethernet unit is capable of transmitting
weight and status for up to 4 loadcells in a single telegram.
It is possible to connect the 4X50 Ethernet unit to an EtherNetIP network,
where it will act as a slave. It will then be possible from the EtherNetIP master
to read status and weight for each of the connected loadcells. Functions as ze-
roing, calibration and calculation of system weight(s) must be implemented
outside the 4X50 in the EtherNetIP master.
By use of DIP-switches it is possible to select measurement time and include
one of 15 different FIR filters, which will be used to filter the loadcell signals.
Exchange of data between master and slave takes place as described in the
following.
2.2 EtherNetIP specification
The EtherNetIP unit confirms with the following EtherNetIP specifications:
Protocol: EtherNetIP
Media: Ethernet
Module type: Slave(/Target)
Communication settings 10MB/s, Half duplex
IP-Address: Fixed (default: 192.168.1.199)
Ethernet connection: RJ45/Cat5
System setup: EEEthSetup software
Software download: RS232 terminal interface
2.3 ATEX (Ex) specification
IMPORTANT: Instrumentation (the 4X50A) must be placed outside the
hazardous zone if the load cells are used in hazardous ATEX (Ex) area.
Furthermore, only ATEX certified load cells and instrumentation can be
used in ATEX applications.

3) Data Exchange
3.1 EtherNetIP communication
Ethernet communication with the 4X50 Ethernet unit uses a single Assembly
consisting of 26 bytes data as specified in the EDS file:
Assembly: Assem3 Input
Assembly instance: 103 (0x67)
Connection: Connection1 Exclusive Owner
Transfer class Class 1
The data bytes are structured like this:
Lc
Register
Lc
Status(0)
Lc
Signal(0)
Lc
Status(3)
Lc
Signal(3)
0
1
2
3
4
5
6
7
20
21
22
23
24
25
The byte order for the individual parts of the telegram is LSB first.. In the fol-
lowing bit 0 will represent the least significant bit in a register.
LcRegister is a word (two bytes) that constitutes a bit register for indication
of expected loadcells. Hence bit 0-3 will be ON, if the corresponding loadcell
address (LC1-LC4) was expected to be connected. LcRegister is always trans-
ferred in 16 bit unsigned integer format.
Furthermore bit 15 will be always ON, while bit 14 will toggle ON and OFF with
1hz (=500ms ON, 500ms OFF)
LcStatus(X) is a word (two bytes) that constitute a register containing the
actual status for loadcell X. LcStatus(X) is always transferred in 16 bit un-
signed integer format. During normal operation this register will be 0, but if
an error occurs some bits in the register will be set resulting in an error code.
A description of the different error codes can be found in the chapter STATUS
CODES.
LcSignal(X) is a double word (four bytes) constituting a register containing
the actual weight signal from loadcell Xin either 32 bit signed integer for-
mat. Note that the value is only valid if the corresponding LcStatus(X) regis-
ter is 0 indicating no error present. The resolution of the loadcell signal is
scaled as described below.
Since only status and weight for the loadcells are transmitted in the telegram,
functions such as status handling, calculation of system weight(s), zeroing and
calibration must be implemented on the EtherNetIP master. Please refer to
the chapter Data Processing for an explanation on how this typically can be
done.

3.3 Scaling
By use of a DIP-switch it is possible to select the desired scaling of the weight
signals. The scaling of the weight signals on the Ethernet is determined by
SWE.1-2 as follows, where the table shows how a given weight is represented
on the Ethernet depending on switch settings:
Weight
[gram]
SWE.1 = OFF
SWE.2 = OFF
(1 gram)
SWE.1 = ON
SWE.2 = OFF
(1/10 gram)
SWE.1 = OFF
SWE.2 = ON

3.4 Measurement time
By use of DIP-switches it is possible to choose between four different meas-
urement times. All loadcells are sampled/averaged over a measurement period
determined by SWE.3 and SWE.4 as follows:
SWE.4
SWE.3

3.5 Filtering
By use of DIP-switches it is possible to include one of 15 different FIR filters,
which will be used to filter the loadcell signals. Thus it is possible, to send the
unfiltered loadcell signals achieved over the selected measurement period
through one of the following FIR filters, before the results are transmitted on
the Ethernet:

4) Data Processing
4.1 Zeroing, calibration and weight calculation
Calculation of system weight(s) is done by addition of the weight registers for
the loadcells belonging to the system. This is explained below. Note that the
result is only valid if all status registers for the loadcells in question indicate no
errors. It should also be noted that it is up to the master to ensure the usage
of consistent loadcell data when calculating the system weight (the used data
should come from the same telegram).
4.1.1 Zeroing of weighing system
Zeroing of a weighing system (all loadcells in the specific system) should be
performed as follows, taking into account that no loadcell errors may be pre-
sent during the zeroing procedure:
1) The weighing arrangement should be empty and clean.
2) The EtherNetIP master verifies that no loadcell errors are present, af-
ter which it reads and stores the actual weight signals for the loadcells
of the actual system in corresponding zeroing registers:
LcZero[x]=LcSignal[x]
3) After this the uncalibrated gross weight for loadcell Xcan be calculated
as:
LcGross[X] = LcSignal[X] –LcZero[X]

4.1.2 Corner calibration of weighing system
In systems where the load is not always placed symmetrically the same place
(for example a platform weight where the load can be placed randomly on the
platform when a weighing is to take place), a fine calibration of a systems cor-
ners can be made, so that the weight indicates the same independent of the
position of the load. This is done as follows:
1) Check that the weighing arrangement is empty. Zero the weighing sys-
tem.
2) Place a known load (CalLoad) directly above the loadcell that is to be
corner calibrated.
3) Calculate the corner calibration factor that should be multiplied on the
uncalibrated gross weight of the loadcell in order to achieve correct
showing as:
CornerCalFactor[x] = (CalLoad)/(LcGross[x])
After this the determined corner calibration factor is used to calculate
the calibrated gross weight of the loadcell as follows:
LcGrossCal[x] = CornerCalFactor[x] * LcGross[x]
4.1.3 Calculation of uncalibrated system weight
Based on the loadcell gross values (LcGross[x] or LcGrossCal[x]), whether
they are corner calibrated or not, a uncalibrated system weight can be calcu-
lated as either:
Gross = LcGross[X1] + LcGross[X2] + …
or:
Gross = LcGrossCal[X1] + LcGrossCal[X2] + …

Version: 2017-06-29, rev.: 3v3a Page: 10
4.1.4 System calibration of weighing system
Based on the uncalibrated system weight a system calibration can be made as
follows:
1) Check that the weighing arrangement is empty. Zero the weighing sys-
tem.
2) Place a known load (CalLoad) on the weighing arrangement.
3) Calculate the calibration factor that should be multiplied on the uncali-
brated system weight in order to achieve correct showing as:
CalFactor = (CalLoad)/(Actual Gross)
After this the determined calibration factor is used to calculate the cal-
ibrated system weight as follows:
GrossCal = CalFactor * Gross
If the determined calibration factor falls outside the interval 0.9 to 1.1
it is very likely that there is something wrong with the mechanical part
of the system. This does not however apply to systems that do not
have a loadcell under each supporting point. For example on a three
legged tank with only one loadcell, you should get a calibration factor
of approximately 3 because of the two “dummy” legs.

5) Installation of System
5.1 Checklist during installation
During installation of the system the following should be checked:
1. All hardware connections are made as described below.
2. Setup IP Address etc. with EEEthSetup as describe below.
3. If necessary the EtherNetIP master should be configured to communi-
cate with the 4X50 Ethernet unit using the supplied EDS file.
4. Set the scaling/resolution of the weight signal by use of SWE.1 as de-
scribed earlier.
5. Set the desired measurement time by use of SWE.3-SWE.4 as described
earlier.
6. Select the desired filter by use of SWE.5-SWE.8 as described earlier.
7. The loadcells are mounted mechanically and connected to BNC connect-
ors in the front panel of the 4X50 unit.
8. The 4X50 Ethernet unit is connected to the EtherNetIP network using
theRS45 Ethernet connector in the front panel.
9. Power (24VDC) is applied at the 2 pole power connectors in the front
panel of the 4X50 unit as described in the hardware section, and the
EtherNetIP communication is started.
10.Verify that the MS lamp and the NS lamp both end up green .
11.Verify that the TxLC lamp (yellow) is lit (turns on after approx. 5 sec-
onds).
12.Verify that the TxBB lamp (green) are lit (after 10 seconds).
13.Verify that NONE of the 1, 2, 3, 4 or D1 lamps (red) are lit.
14.Verify that the 4X50 Ethernet system unit has found the correct
loadcells (LcRegister), and that no loadcell errors are indicated (LcSta-
tus(x)).
15.Verify that every loadcell gives a signal (LcSignal(x)) by placing a load
directly above each loadcell one after the other (possibly with a known
load).
The system is now installed and a zero and fine calibration is made as de-
scribed earlier. Finally verify that the weighing system(s) returns a value cor-
responding to a known actual load.
Note that in the above checklist no consideration has been made on which
functions are implemented on the EtherNetIP master.

6.2.1 Connection of power
The 4X507 system unit is powered by applying +24VDC on the green two pole
connectors (J2 and J3) as specified on the front panel of the 4X50 system unit.
This powers the entire 4X50 system unit including the loadcells.
IMPORTANT: The used power supply must be stable and free of transients. It
may therefore be necessary to use a separate power supply dedicated to the
weighing system, and not connected to any other equipment.
NOTE: If the loadcells are to be placed inside an EX area, then the 4X50 sys-
tem unit itself MUST be placed outside the EX area, and the 4X50 system unit
MUST be supplied as follows:
1) The 2 pole connector (J3), located to the right above the 4 pole DIP-switch
block, MUST be powered by a 4051A power supply (+24VDC ATEX approved)
from Eilersen Electric.
2) The 2 pole connector (J2), located to the left above the RJ45 Ethernet con-
nector, MUST be powered by a separate +24VDC, that has NO connection to
the ATEX approved +24VDC from the above mentioned 4051A power supply.
6.2.2 Connection of loadcells
The loadcells must be connected to the available BNC connectors in the front
panel of the 4X50 system unit. The loadcells are connected starting with the
connector marked 1 and continuing onwards in rising order. Thus if three
loadcells are to be connected, they should be connected to the BNC connectors
marked 1, 2 and 3.
6.2.3 Ethernet connector
The front panel of the 4X50 system unit is equipped with a standard Ethernet
RJ47 connector for Cat5 cables.
6.2.4 SW1 settings
The front panel of the 4X50 system unit is equipped with a 4 pole DIP switch
block named SW1. These switches are mounted on the 4040 communication

6.3 Hardware Selftest
During power-on the 4X50 ethernet system unit will perform a hardware selft-
est. The test will cause the light emitting diodes D1, MS and NS to flash short-
ly one at a time.
6.4 Update times
The 4X50 Ethernet system unit samples the loadcell signals over a period of 20
ms, 100 ms, 200 ms or 400 ms. The hereby found loadcell signals are used in
the EtherNetIP communication until new signals are achieved when the next
sample period expires. Update times across the EtherNetIP communication de-
pends on the specific EtherNetIP configuration (switches, number of units, mas-
ter scan times etc.) and are beyond the scope of this document.

7) Appendices
7.1 Appendix A –Setup
The MAC address of the module is preset to a unique value within the Eilersen
Electric A/S range. The default settings for IP address etc. are
DHCP: Disabled
IP Address: 192.168.1.199
Subnet mask: 255.255.255.0
Gateway: 192.168.1.254
These defaults can be altered by the EEEthSetup software- please refer to the
separate users guide for further details.
7.2 Appendix B –Allen Bradley connection
To connect the module to an Allen Bradley (Rockwell Automation) PLC using
the Logix 5000 software the following must be observed:
1. Use the “ETHERNET MODULE Generic Ethernet Module
2. Set connection format to “SINT”
3. Set “Input” “Assembly instance to 103, “Size” 26 (8-bit)
4. Set “Output” “Assembly instance to 102, “Size” 2 (8-bit)
5. Set “Configuration” “Assembly instance to 101, “Size” 1 (8-bit)
7.3 Appendix C –Omron connection
The supplied EDS file can be used in the Omron configurator.
But please beware that the terms “input” and “output” may be confusing in
the Omron configurator. These terms are always from the PLC’s point of view.
So the data from the 4x50 module to the PLC is referred to as “input” even
though it is actually an output from the 4x50.
The data from the 4x50 module is found the input assembly 103.
The output and the confirmation assemblies (101 and 102) are not used
7.4 Appendix D –Internal Features
7.4.1 4050 Ethernet module
This chapter describes possible connections, DIP-switch settings and jumper
settings that are available internally on the 4050 Ethernet module. These will
