2) Introduction
2.1 Introduction
This document describes the use of a TE67X000002150 Ethernet module from Alfa Laval
Kolding A/S, when it is equipped with the program listed on the front page.
With the program specified on the front page, the TE67X000002150 Ethernet module is capable of
transmitting weight and status for up to 4 load cells in a single telegram. Each load cell is connected to
the Ethernet module through a load cell interface module.
It is possible to connect the TE67X000002150 Ethernet module 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 load cells. Functions as zeroing, calibration and calculation of system weight(s) must be
implemented outside the TE67X000002150 in the EtherNetIP master.
Exchange of data between master and slave takes place as described in the following.

3) Data Exchange
3.1 EtherNetIP communication
Ethernet communication with the TE67X000002150 Ethernet module 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 following bit 0 will represent
the least significant bit in a register.
LcRegister is a word (two bytes) that constitute a bit register for indication of connected load cells
detected during power on. Hence bit 0-3 will be ON, if the corresponding load cell (address) was
detected during power on. LcRegister is always transferred 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 load cell
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, see page 20.
LcSignal(X) is a double word (four bytes) constituting a register containing the actual weight
signal from load cell X in 32 bit signed integer format. Note that the value is only valid if the
corresponding LcStatus(X) register is 0 indicating no error present. The resolution of the load cell
signal is selectable. Please see below.
Since only status and weight for the load cells 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 page 9 for an explanation on how
this typically can be done.

3) Data Exchange(continued)
3.5 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 SW1.1-2 as follows, where the table shows how a
given weight is represented on the Ethernet depending on switch settings:
Weight
[gram]
SW1.1 = OFF
SW1.2 = OFF
(1 gram)
SW1.1 = ON
SW1.2 = OFF

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 load cells belonging to
the system. This is explained below. Note that the result is only valid if all status registers for the load
cells in question indicate no errors. It should also be noted that it is up to the master to ensure the
usage of consistent load cell 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 load cells in the specific system) should be performed as follows,
taking into account that no load cell 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 load cell errors are present, after which it reads and
stores the actual weight signals for the load cells of the actual system in corresponding zeroing
registers:
LcZero[x]=LcSignal[x]
3) After this the uncalibrated gross weight for load cell X can be calculated as:
LcGross[X] = LcSignal[X] – LcZero[X]
4.2 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 corners 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 system.
2) Place a known load (CalLoad) directly above the load cell that is to be corner calibrated.
3) Calculate the corner calibration factor that should be multiplied on the uncalibrated gross
weight of the load cell 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
load cell as follows:
LcGrossCal[x] = CornerCalFactor[x] * LcGross[x]

Status and weight transfer using EtherNetIP
IM-TE91K013-EN2
4) Data Processing (continued)
4.3 Calculation of uncalibrated system weight
Based on the load cell gross values (LcGross[x] or LcGrossCal[x]), whether they are corner calibrated
or not, an uncalibrated system weight can be calculated as either:
4.4 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 system.
2) Place a known load (CalLoad) on the weighing arrangement. NOTE: In order to achieve a
correct calibration of the system it is recommended, that the used calibration load is at least
50% of the system capacity.
3) Calculate the calibration factor that should be multiplied on the uncalibrated system weight in
order to achieve correct showing as:
CalFactor = (CalLoad)/(Actual Gross)
After this the determined calibration factor is used to calculate the calibrated 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 load cell under each supporting point. For example on a three legged tank with only
one load cell, 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. Connect the TE67X000002150 Ethernet to a PC with a RS232 connection and setup IP Address
etc. as describe below.
3. If necessary the EtherNetIP master should be configured to communicate with the
TE67X000002150 Ethernet module using the supplied EDS file.
4. Set the scaling/resolution of the weight signal by use of SW1.1-2 as described above.
5. The load cells are mounted mechanically and connected to the TE67X000002150 Ethernet module
using their corresponding load cell interface module. The load cell addresses are set using the
DIP-switches on the load cell interface modules, so that they forth running from address 0 (0-3).
6. The TE67X000002150 Ethernet module is connected to the EtherNetIP network using the RS45
Ethernet connector in the front panel.
7. Power (24VDC) is applied through the two pole connector (J2). The EtherNetIP communication is
started.
8. Verify that the MS lamp and the NS lamp both end up green.
9. Verify that the TxBB lamp (green) on the Ethernet module is lit (after 10 seconds), and that the
TxBB lamps on all the load cell interface modules are also lit (can flash slightly).
10. Verify that none of the D1 or D2 lamps are lit.
11. Verify that the TE67X000002150 Ethernet module has found the correct load cells (LcRegister),
and that no load cell errors are indicated (LcStatus(x)).
12. Verify that every load cell gives a signal (LcSignal(x)) by placing a load directly above each load
cell one after the other (possibly with a known load).
The system is now installed and a zero and fine calibration is made as described earlier. Finally verify
that the weighing system(s) returns a value corresponding 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.
