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
(1/10 gram)
SW1.1 = OFF
SW1.2 = ON
(1/100 gram)

SW1.2 = ON

3.6 Measurement time
By use of a DIP-switch it is possible to choose between two different measurement times. All load cells
are sampled/averaged over a measurement period determined by SW1.3 as follows:
SW1.3 Measurement
i
OFF
200 ms
ON
20 ms
The hereby found load cell signals (possibly filtered) are used on the Ethernet until new signals are
achieved when the next sample period expires.

3) Data Exchange(continued)
3.7 Filtering
By use of DIP-switches it is possible to include one of 15 different FIR filters, which will be used to filter
the load cell signals. Thus it is possible to send the unfiltered load cell signals achieved over the
selected measurement period through one of the following FIR filters, before the results are transmitted
on the Ethernet:
SW1.
SW1.5
SW1.6

No.
