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.

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.

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.

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:

WWW.EILERSEN.COM

MOD

PCV

PCD

MDS

PCA

PNU

PVA

CTW

STW

MRV

MAV

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.

WWW.EILERSEN.COM

Bit 7 Bit 0

RS: Reference value selector (Values: 0..15)

AS: Actual value selector (Values: 0..15)

–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.

Bit 7 Bit 0

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

No request

Request parameter value

Change parameter value (2 bytes)

Change parameter value (4 bytes)

Others

Reserved for future use

The contents of RC has the following function during response:

WWW.EILERSEN.COM

RESPONSE

FUNCTION

No response

Transfer parameter value (2 bytes)

Transfer parameter value (4 bytes)

Request rejected (incl. Error#, see later)

Cannot be serviced by PCV interface

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

Illegal command for this PNU or PNU not used.

Reserved for future use

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.
