1 • INTRODUCTION

The “GFW adv” series of modular power controllers with EtherCAT (Ethernet for Control Automation Technology)

Fieldbus interface allows rapid integration of a large number of compact control units for the temperature control and

management of the heating device in advanced automation systems (such as PLCs, Supervision Systems, etc.) inter-

connected by communication networks and protocols defined by the standard.

It is not the purpose of this manual to describe the “EtherCAT” Fieldbus; it is assumed that the user is familiar with it

and that for any updates he/she refers to the official website of EtherCAT Technology Group, www.ethercat.org.

It is also assumed that the user is already familiar with the technical characteristics of GFW products, contained in

manuals included with the product or downloadable from the GEFRAN S.P.A. website. www.gefran.com.

This manual refers to the 2 variants of the GFW versions, whose order codes are E2/E7:

- E2 - 2009 Specification - 2.50.24 Stack - ETH2 Card with netX50

- E7 - 2016 Specification- 4.7.0.3 Stack - ETH7 Card with netX51

As for the E2 version, this manual refers to sizes 40-250A only, whereas the E7 version includes sizes 40-250A and

400-600A.

Where not specified, the descriptions refer to all the possible configurations.

Compared to the E2 version, the E7 one has new functions:

- Bridge mode (up to 12 zones - 4 GFW)

Autoscan master support

2ndary station alias support

4 • GENERAL COMMUNICATION ARCHITECTURE

The communication architecture implemented in the GFW communication card converts EtherCAT dialog data into

Modbus RTU packets transmitted and received via serial line.

The scheme is as follows:

80427A_MSW_GFW-ETHERCAT_07-2018_ENG

5 • INSTALLATION

CONNECTION TO ETHERCAT NETWORK

Ethernet RJ45 Connectors

To connect the devices to the EtherCAT network, proceed in sequence from the master to the slaves as shown below

680427A_MSW_GFW-ETHERCAT_07-2018_ENG

Remember to use a CAT5 Ethernet cable or higher (STP or UTP). The distance between the two nodes must not

exceed 100 meters.

E7 devices allow you to use the card as a bridge so as to connect up to 4 GFW (12 zones) in series to every etherCAT

node.

Below a maximum conguration obtained connecting 4 GFWs (12 zones) between them via Modbus (only for E7 ver-

sions).

80427A_MSW_GFW-ETHERCAT_07-2018_ENG

SELECTION OF ROTARY SWITCHES AND DIP SWITCHES

The hex rotary switches on the GFW indicate the node address of the Modbus/RTU slave network acquired when the

instrument is switched on.

The GFW is factory-set with the rotary switches in the “0” position. It is the customer’s task to put them in the correct

position, considering that ONLY the following combinations apply for EtherCAT:

Node Address E2 E7

1 Rotary X 10=0, Rotary X1=1 Rotary X 10=0, Rotary X1=1 for node 1

2 - Not admitted - Rotary X 10=0, Rotary X1=2 for node 2

3 - Not admitted - Rotary X 10=0, Rotary X1=3 for node 3

4 - Not admitted - Rotary X 10=0, Rotary X1=4 for node 4

The other positions of the rotary switches refer to special functions.

The GFW configuration dip-switches, described in manual /2/ in the chapter “Description of Dip-Switches,” let you define

the instrument’s work mode.

Specifically, when Dip “6” is “ON,” it lets you reset the factory values to “POWER ON.”

AFTER YOU HAVE RESTARTED THE INSTRUMENT WITH FACTORY VALUES, REMEMBER TO RETURN DIP “6”

TO “OFF”�

DIP “7” MUST NECESSARILY BE “OFF” AND THE ROTARIES IN POSITION 01!

BEHAVIOR OF COMMUNICATION CARD LEDS AT POWER-UP

E2:

The communication card has two 2-color (green, red) LEDs, H4 and H6, which light in the following sequence during

power-up:

• H4 red and H6 red, ON for 1 second

• H4 green and H6 green, ON for 1 second

• H4 red and H6 red, ON for 1 second

• H4 green and H6 green, ON for 1 second

• H4 red and H6 red, ON for 1 second

• H4 green and H6 green, ON for 1 second

• H4 and H6m normal operation

E7:

No start-up sequence

6 • PROCESS DATA OBJECTS (PDO)

There are 2 PDO Rx in reception (from master to slave) and 2 PDO Tx in transmission (from slave to master) for process

data exchange (PDO).
