1. Warnings and legal information

Legal information and responsibility

Thomson Technology takes no responsibility for installation or operation of the generator set. If there

is any doubt about how to install or operate the engine controlled by the unit, the company responsible

for the installation or the operation of the set must be contacted.

Electrostatic discharge awareness

Sufficient care must be taken to protect the terminals against static discharges during the

installation. Once the unit is installed and connected, these precautions are no longer necessary.

Safety issues

Installing the unit implies work with dangerous currents and voltages. Therefore, the installation should

only be carried out by authorised personnel who understand the risks involved in working with live

electrical equipment.

Factory settings

The unit is delivered with certain factory settings. Given the fact that these settings are based on

average values, they are not necessarily the correct settings for matching the individual engine.

Thus precautions must be taken to check the settings before running the engine.

Definitions

Throughout this document a number of notes and warnings will be presented. To ensure that these

are noticed, they will be highlighted in order to separate them from the general text.

Notes

Warning

The notes provide general information, which will be helpful for the reader to

bear in mind.

The warnings indicate a potential

ly dangerous situation, which could result in

death, personal injury or damaged equipment, if certain guide

lines are not

followed.

Be aware of the hazardous live

currents and voltages. Do not touch any AC

measurement inputs as this could lead to injury or death.

The units are not to be opened by unauthorized personnel. If opened anyway, the

warranty will be lost.

2. Description of option

Feature EXP

EXP is a CANbus based serial interface for external I/O controllers. This option gives the possibility

to add more inputs and outputs to MEX 310 controllers via the CANbus.

MEC 310 controllers support the CANopen protocol. This protocol is based on the CANopen

Application Layer and Communication Profile Specification CiA Draft Standard 301 Version 4.02. It

is not the purpose of this document to describe all the functionalities of the CANopen

communication. The CANopen is implemented and runs according to the CANopen standards and

needs no special attention from the user.

MEC 310 interface

Terminal description

The CAN #2 terminals 57(H) and 59(L) are also used for EAP 300 (see feature EAP 300).

Installation of Beckhoff controller (bus coupler)

The following is a step-by-step guide to set up the communication between the MEC 310 unit and

the Beckhoff modules.

Beckhoff controller setup

1. Set the Baud rate to ‘AUTO’.

2. Set the Node ID to a value between 10 and 64.

3. Connect the required I/O modules to the controller.

4. Mount the ‘End Bus Terminal’: KL9010 module.

CANbus wiring

5. Disconnect power to the MEC 310 and the Beckhoff controller.

6. Connect the CANbus wires to the Beckhoff controller according to the ‘Installation

Instructions’.

MEC 310 unit

7. Connect power to the MEC 310 unit and the Beckhoff controller.

8. Set CAN1 type (menu 7971 = H8.2 or menu 7981 = H8.8) to 'Beckhoff comm.'.

9. Set the Baud rate (default: 125kbit/s).

10. Set the Node ID (menu 7973/7983) to the same value as selected on the Beckhoff

controller.

11. Communication between the MEC 310 unit and the Beckhoff controller is now established.

MEC 310: Please refer to the document ‘Installation Instructions and

Reference Handbook’.

MEC 310: Menu 7971 and 7981 are not available.

MEC 310: Menu 7973 is not available.

Documentation regarding Beckhoff modules can be found at www.beckhoff.com.

MEC 310: The Baud rate is fixed at 50kbit/s.

Communication fault: In case any LEDs on the Beckhoff controller are

flashing continuously for more than 5s, please refer to the chapter ‘Fault

finding’ in this document.

12. To see the available external I/Os, retrieve the parameters from the MEC 310 unit with the

TPS 300 software.

13. Click on ‘External I/O’ in the TPS 300 software to see or change settings for external I/O

modules.

Functional check of external I/O modules

Alarm messages in display

Alarm message Description

Ext. I/O unk. module The module used is not supported by the MEC 310 unit.

Ext. I/O new setup If modules are changed or have changed place in the row of

modules, this error message will be active. Can be removed by reset

in menu 7974 ‘Reset’.

Module check

The module check can only take place using the TPS 300 software.

Modules are presented in the order by which they are mounted, counting from the CANbus controller

side.

External I/Os will only be shown in the TPS 300 software if they are present.

The result of the check can be read in status channels 12950-12983.

The Beckhoff module transmits a status message to the unit. This message is a HEX value for digital

I/O units and decimal for controllers/analogue I/O units.

MEC 310 APPLICATION NOTES - External I/O Modules

PM104 R0 09/08/20 Page 7 THOMSON TECHNOLOGY

Digital I/O

1. digit: 8 for digital

2. digit: Number of input/output (2, 4 or 8)

3. digit: Not used (0)

4. digit: Input [1] or output [2]

In the TPS 300 software, all values are presented as decimal values, so the HEX values for the

digital I/O modules are translated as follows:

Inputs:

0x8201h = -32255d

0x8401h = -31743d

0x8801h = -30719d

Outputs:

0x8202h = -32254d

0x8402h = -31742d

0x8802h = -30718d
