Introduction
This document describes the use of the External Module option on the 5024G Weighing Ter-
minal from Eilersen Electric. With the software version stated on the front page and with the
External Module option enabled as well as a on RS485 externally connected communications
module (MCE2035, 2070, MCE9637 or 2050) from Eilersen Electric the system can communi-
cate with an external controller/PLC using Profibus-DP, PROFINET, DeviceNet or Ethernet-IP.
With the later stated software versions installed in the external module the external commu-
nication module can transfer 14 input bytes from the 5024G terminal to the Profibus-DP /
PROFINET / DeviceNet / Ethernet-IP master, and transfer 14 output bytes from Profibus-DP /
PROFINET / DeviceNet / Ethernet-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 External Module option. For general information on the oper-
ation of the 5024G please see the ‘Users guide’.
Installation of external module
The used external module (xxxx) must be connected to the 5024G weighing terminal and to
the external controller/PLC according to the description in the appropriate appendix.
Please notice:
•no matter what module type, the module must be connected to the 5024G terminal
using a RS485 connection.
•depending on module type, the module must be connected to the external control-
ler/PLC using bus type as described in the appendix belonging to the module.
•depending on module type, the 5024G terminal must be configured to exactly the
module used according to the guidelines below.
How to
–Enable and configure external module on 5024G
Below the EXTERNAL MODULE screen is shown when a MCE2035 (MCExx35) module has
been enabled.

6
WWW.EILERSEN.COM
In this screen the external module is shown and can be changed. A cursor (inverted text) in-
dicates the currently selected module. With this version of the software only one module can
be installed.
The line with module data shows in forth running order after the Device Index (always 0 in
this software version): Device Type, Device Address, Endian, Status, Error Counter, Bytes Out
and Bytes In, which all are described in detail below.
Enable or change Device Type
To enable or select a new module type (Device Type) press on the selected line, and from
the EXTERNAL MODULE menu select the DEVICE TYPE menu item to get the selection list
with possible module types. Possible module types are MCExx35 Profibus-DP module,
MCE9637 DeviceNet module, 2050 Ethernet module and 2070 PROFINET module. If no ex-
ternal module is enabled the 5024G display will show “-------”/ ”None”.
Once a module type is enabled/selected the other settings (see descriptions below) are set to
default values, which should normally be used.
Set/Read Device Address
The address is the entered address plus the base address for the module type selected.
During change enter a number in the interval 0-15. With this software version where only
one external module can be connected, 0 is the normally entered address value.
Set/Read Endian
Endian of the individual data values transferred: MSB most significant byte first: Big endian.
LSB least significant byte first: Little endian. MSB is normally used with Profibus-DP and
PROFINET while LSB is normally used with all other types of modules.
Read Status
00: Communication up and running.
40: Connection established earlier to the module has been lost.
80: No connection to the module has been established.
Read Error Counter
Current number off errors in communication.

7
WWW.EILERSEN.COM
Set/Read Bytes Out
Number of bytes to be sent from the 5024G to the external module and from there to the
Profibus-DP/PROFINET/DeviceNet/Ethernet master. This is the number of input bytes in the
Profibus-DP/PROFINET/DeviceNet/Ethernet master.
The value must be the same as the value in the external module. Normally this is 14.
Set/Read Bytes In
Number of bytes to be received in the 5024G from the external module and transmitted from
the Profibus-DP/PROFINET/DeviceNet/Ethernet master. This is the number of output bytes in
the Profibus-DP/PROFINET/DeviceNet/Ethernet master.
The value must be the same as the value in the external module. Normally this is 14.
–Monitor external module data on 5024G
Below the EXTERNAL MODULE DATA screen is shown when a MCE2035 (MCExx35) module
has been enabled.
This screen will show the data sent to the external module (OUT) and the data received from
the external module (IN).
The following keys can be used for the described special functions:
Selects entry of the selected input data byte for test purposes. If an external module
is communication the value will immediately be overwritten by the value receive
form the external module.
T
Toggles the cursor between the output and the input bytes.
Protocol description
–External communication using PPO
The communication with the external module is made using a 'parameter-process data object'
(PPO) consisting of 14 bytes data. This telegram (object) is used during both reception and
transmission of data. The structure of this telegram is as follows:

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.
–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.

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.

11
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.

The 2035 PROFIBUS-DP module is equipped with DIP-switch blocks that have the following
function:
SWITCH
FUNCTION
Sw1.1-Sw1.4
Selection of AUX communication address
The address is selected as the DIP-switches are binary coded, so that Sw1.1 is
MSB and Sw1.4 is LSB. Note that these switches are only read during power on.
The address should not be set so that the module has an address that matches
another Profibus-DP module on the same AUX bus. The modules should be
numbered from 0 and upwards without skipping any numbers. If only one mod-
ule of a given type is connected to the AUX bus all switches should be OFF.

FUNCTION
Sw2.1
Reserved for future use
Sw2.2-Sw2.8
Selection of PROFIBUS-DP communication address
The address is selected as the DIP-switches are binary coded, so that Sw2.2 is
MSB and Sw2.8 is LSB. Note that these switches are only read during power on.
MCE2035 Jumper settings
The 2035 PROFIBUS-DP module is equipped with 4 jumpers. These jumpers have the follow-
ing function:
JUMPER
FUNCTION
JU1
Baudrate on the AUX bus.
OFF: Communication at 9600 bps.
ON: Communication at 115200 bps.
(MUST be in this position for communication with 5024G)
(Normally the jumper will be mounted on delivery.)
JU2-JU4
Alternative termination of the Profibus-DP.
If R17, R21 and R22 are mounted these jumpers can be used to connect the
termination resistors, so this is done directly on the module and not the normal
way in the Profibus-DP connectors

MCE2035 Profibus-DP connector
The 2035 PROFIBUS-DP module is equipped with a nine pole female sub-D connector (J1) for
connection to the PROFIBUS-DP network. The connector is a standard PROFIBUS-DP con-
nector. Termination of the PROFIBUS-DP should take place in the sub-D connector (male) of
the cable. The specific terminals in the connector have the following function:
