Introduction
This document describes the use of the Ethernet-IP option on the 5024G Weighing Terminal
from Eilersen Electric. With the software version stated on the front page and with the
Ethernet-IP option enabled the system can communicate with an external controller/PLC us-
ing Ethernet-IP.
With the stated software version installed the 5024G terminal can transfer 14 input bytes
from the 5024G terminal to the Ethernet-IP master, and transfer 14 output bytes from Ether-
net-IP master to the 5024G terminal.
Exchange of data between 5024G terminal and the external controller/PLC is made according
to the profile/protocol described later (see Protocol description).
This manual only describes the Ethernet-IP option. For general information on the operation
of the 5024G please see the ‘Users guide’.
How to
–Configure Ethernet-IP settings on 5024G
For the terminal to perform Ethernet-IP communication directly on its RJ45/Cat5 Ethernet
connector (J7) with a connected Ethernet-IP master the Ethernet settings must be config-
ured, and the Ethernet-IP protocol must be enabled as described in the following.
Address settings
Ip addresses, subnet masks etc. are normally set from a PC with the EEConnect software.
Please refer to the EEConnect documentation for further details.
If the terminal is unreachable e.g. due to network topology, the Ethernet settings can be en-
tered in the SETUP ETHERNET screen:

5
WWW.EILERSEN.COM
Enable Ethernet-IP protocol
The Ethernet-IP protocol must be enabled. This is done in the ETHERNET PROTOCOLS screen
shown below:
In the ETHERNET PROTOCOLS screen the ’EtherNetIP’ parameter is selected using the cursor,
and is pressed to enable or disable the Ethernet-IP protocol. A Xin the corresponding box
indicates the protocol is enabled.
–Check EtherNetIP communication status
In the ETHERNET STATUS screen, the status of the EtherNetIP communication can be read:
This requires that the EtherNetIP protocol is selected from the menu (the
F
key) in the
ETHERNET STATUS screen. The currently selected protocol is shown in the upper right corner
of the screen. If the EtherNetIP protocol is selected, then the EtherNetIP status indications
for both Module Status (MS) and Network Status (NS) are shown, corresponding to the nor-
mal MS and NS lamps as follows:
-their respective color (in parenthesis): which can be lit, flashing or turned off (blank).
-and a following short explanatory status text.

6
WWW.EILERSEN.COM
The Module Status (MS) and Network Status (NS) indications can be lit/flashing in different
colors depending on module and network status. Please see Appendix E –Ethernet-IP status
indications for a more detailed explanation of the different/possible status indications.
Protocol description
–Ethernet-IP communication using PPO
The Ethernet-IP communication is made using a 'parameter-process data object' (PPO) consist-
ing of 14 bytes data. This telegram (object) is used during both reception and transmission of da-
ta. The structure of this telegram is as follows:
MOD
PCV
PCD
MDS
PCA
PNU
PVA
CTW
STW
MRV

Byte 1 Byte 14
The telegram is made up of 3 blocks; a MOD part (1 byte), a PCV part (the next 7 bytes) and a
PCD part (the last 6 bytes). The three blocks are as follows:
MOD (Mode)
MDS (Byte 1): Mode selector
PCV (Parameter-Characteristic-Value)
PCA (Byte 2): Parameter Characteristics
PNU (Bytes 3-4): Parameter number
PVA (Bytes 5-8): Parameter value
PCD (Process Data)
CTW (Bytes 9-10) (Master to Slave): Control Word
STW (Bytes 9-10) (Slave to Master): Status Word
MRV (Bytes 11-14) (Master to Slave): Main Reference Value
MAV (Bytes 11-14) (Slave to Master): Main Actual Value
In the following the meaning of the individual blocks of the telegram is explained further.
IMPORTANT: During transfer/reception of data (i.e. the MAV) it is up to the master
(the PLC) to ensure consistent data, when a parameter consisting of several bytes is
read/updated and when AS/MAV or RS/MRV is read/set.

WWW.EILERSEN.COM
–MOD
The MOD part of the telegram indicates which value is to be transferred as Main Reference Val-
ue (MRV) and as Main Actual Value (MAV). Please see below for further information.
MDS
MDS contains an RS part for selection of Main Reference Value (MRV) and an AS part for selec-
tion of Main Actual Value (MAV), as shown in the figure below.

–PCV Description
The PCV part of the telegram is made up of a PCA part, a PNU part and a PVA part. The function
of these different parts of the PCV part is described here.
PCA
The PCA part contains an RC part for 'request' and 'response' indication.

RC
RC: Request/Response Characteristics (Values: 0..255)
RC is used by the master to tell the slave which ’request’ is desired. Similarly the slave uses
RC to inform the master the status of the received 'request' (’response’). The contents of RC
has the following function during ’request:
REQUEST
FUNCTION
0
No request
1

2

The contents of RC has the following function during response:

WWW.EILERSEN.COM
RESPONSE
FUNCTION
0
No response
1
Transfer parameter value (2 bytes)
2
Transfer parameter value (4 bytes)
3
Request rejected (incl. Error#, see later)
4

Others
Reserved for future use
PNU
The PNU part indicates the parameter number of the parameter to be read/changed. The pa-
rameters and their function is described below.
PVA
The PVA part contains 4 bytes for reception and transmission of parameter values. The PVA
part transfers '2 byte' parameters in bytes 5 and 6, while '4 byte' parameters are transferred
in bytes 5 and 8.
If the slave rejects a request from the master the RC part assumes the value 3 (see above)
and the error number itself is transferred in the PVA part (bytes 5 and 6). The following error
indications are possible:
ERROR #
CAUSE
0
Illegal command for this PNU or PNU not used.
1
Reserved for future use
2
Upper or lower limit exceeded
–PCD Description
The PCD part of the telegram is made up of a CTW/STW part and a MRV/MAV part. The func-
tion of these two parts of the PCD part is described here. Note that the PCD part (the last 6
bytes) always transfers these data disregarding the contents of the PCV part.
CTW/STW
During communication from the master to the slave, the first two bytes of the PCD part are used
as a Control Word (CTW). Using the Control Word (CTW) it is possible to tell the slave how to re-
act as different commands can be transferred to the slave.
During communication from the slave to the master, the first two bytes of the PCD part are used
as a Status Word (STW). Using the Status Word (STW) it is possible for the master to gain infor-
mation on the status of the slave.

9
WWW.EILERSEN.COM
MRV/MAV
During communication from the master to the slave the last four bytes of the PCD part are
used as a Main Reference Value (MRV); a setpoint. Using the RS defines exactly which value
is transferred as MRV.
During communication from the slave to the master the last four bytes of the PCD part are
used as a Main Actual Value (MAV); the actual value. Using the AS defines exactly which val-
ue is transferred as MAV.
–Communication overview
Please note the following:
1. All weights are transferred as shown in the display without a decimal point (i.e. 300.0 kg
is transferred as 3000 and 67.2 kg is transferred as 672).
2. All negative numbers are transferred as 2-complement numbers.
3. Actual unit and decimal point position can be read from the appropriate parameter.
4. In Ethernet-IP communication the Endian used is LSB (Least Significant Byte first).
