ECOM Module Introduction
Several Ethernet Communication (ECOM) modules are currently available for use with
DL05/06, DL205 and DL405 PLC systems. The ECOM modules are shown below. These
modules provide a low-cost, high-speed Ethernet link for PLC systems. The modules are easy
to set up and install on 10/100BaseT (twisted pair, copper wire) or 10BaseFL (fiber optic)
Ethernet networks.
LEDs on the face of each module give vital information about the status of the module and the
communication link. The 10/100BaseT modules use standard RJ45 modular connectors, and
the 10BaseFL modules use ST style bayonet connectors.
NOTE: If you are using a D0-06LCD in your DL06 PLC, the date code for the display unit must be 032A_ or
later to be compatible with the H0 series ECOM modules.
ECOM Communication Possibilities
You can use the ECOM modules to share data between two or more DirectLOGIC PLCs
or between DirectLOGIC PLCs and personal computers. The H0/H2/H4 -ECOM100
additionally allows client/server communications with other Ethernet devices using the
MODBUS TCP protocol. Communication between PLCs/MODBUS TCP devices is
accomplished by using the Read/Write (RX/WX) instructions which are available in the
DirectSOFT Programming Software Users Manual. Chapters 4 and 5 explain the use of the
RX/WX instructions.
NOTE: Please review intelligent instructions (IBox) in Chapter 5 of the user manual for the PLC you are
using, which simplify this and other functions.

You can also use a personal computer running DirectSOFT Programming Software to program
your PLCs over the Ethernet network. It is just like programming through the programming
port on the CPU, but with the convenience of doing it from a single location.
Use DirectSOFT programming software to program the complete DirectLOGIC family of PLCs
(the DL105 and DL305 series are the only PLCs that cannot be programmed over Ethernet).
Chapter 2 will indicate the CPUs which can be used with the ECOM modules.
NOTE: We recommend using a dedicated network for your PLC control applications. For more information
see Chapter 2, Setup and Installation
Your Network PC
PCs running our KEPDirect for PLCs software can establish Ethernet links for exchanging
information with DirectLOGIC 05/06/205/405 PLCs.
You can use a personal computer equipped with a 10/100BaseT or 10BaseFL network adapter
card and NetEdit3 software to configure the ECOM module over the network. You can also use
NetEdit3 for troubleshooting certain communication problems. The NetEdit3 utility is available
for download at http://www.automationdirect.com.

Frequently Asked Questions
.Q How can I speed up my ECOM communications?
.A Try shortening the scan time of the PLC (the PLC
allows only one ECOM transaction per scan).
.Q What causes “Task code error response” with extended E353 error?
.A Error is from the PLC and means “timeout in the background communications”.
Error is due to a backplane communication problem (ECOM, DCM, etc.).
.Q Can an ECOM be configured to talk through a gateway?
.A Yes. You configure the gateway to reroute traffic to
and from the ECOM via port 7070 (hex).
.Q When using a DL205 with an ECOM, is there a way to turn on the PLC
outputs from a computer using a non- Windows operating system?
.A Host Engineering has what is called an Ethernet SDK (software developers
kit) which can normally be downloaded (free) from their website. However,
this will be useless for your system, but to accommodate your operating
system, you can fill out a form located on the Host Engineering website
and request the source code for the Ethernet SDK. This is necessary
so that Host Engineering will know who is using their source code.
The source code can then be recompiled to work on your system.
With the SDK recompiled for your system, you can use CCM (i.e.
DirectNET) protocol to turn on PLC outputs by simply knowing
the memory types and ranges as required for syntax.
The request form and details about the SDK can be found on the Host
Engineering homepage (www.hosteng.com). Once there, click on “EBC/
ECOM/EDRV” under “S/W Developer Kits” in the left- hand column.
.Q What is the fastest way to get data from PLC to PLC?
.A Install ECOM in both PLCs and use the RX/WX commands is the quickest
way to do this. It is much faster that using serial communication.
.Q Can the ECOM do a broadcast message to multiple slave devices?
.A No.
.Q Can the MAC address be changed?
.A The MAC address is burned into ROM on the module and is set just before it
leaves the factory. There is no logical way for any protocol to change this address.
Host Engineering’s range for Ethernet (MAC) addresses is 00.E0.62.xx.xx.xx.

ECOM Network Identifiers
This section describes network identifiers that can be assigned to the ECOM module. Each
module must be assigned at least one unique identifier to make it possible for PCs or other
ECOMs to recognize it on the network. Four methods of identifying the ECOM module give
it the flexibility to fit most networking schemes.
The four ECOM identifiers are:
• Module ID
• Name
• IP (Internet Protocol) Address
• Ethernet (MAC) Address
The first three are user-selectable. The last one is set at the factory. Each of the identifiers is
discussed in this chapter. If you have more than a few ECOMs on your network, consider
making a chart or spreadsheet of network IDs, as shown below:
The decision about which type of identifier to use is an important one. Much of the decision
depends on the requirements of your particular application. PC-to-PLC communications are
generally better accommodated with one type of identifier while PLC-to-PLC communications
require a different type. Ease of maintenance and troubleshooting also must be considered
before deciding which type to use.
The identifiers are used to link your PC to your PLC or one PLC to another PLC. The flexible
design of the module allows you to use different identifiers for different links to the same
module. This is particularly important if you require both PC-to-PLC and PLC-to-PLC
communications on the same network.
The following table summarizes Network Identifiers and their uses:

Module ID
A Module ID is required for PLC-to-PLC communications, and it can be set either of two
ways. You can assign the Module ID:
• Using the DIP switches on the module.
• Using the configuration tools in NetEdit3
• HTML Configuration (after IP address is assigned to module using
NetEdit3; described in Chapter 5; H0/H2/H4- ECOM100 only)
Use the DIP switch if you want the ability to install or change modules without using a PC to
set the Module ID. Set the module’s DIP switch, insert the module in the base, and connect the
network cable. Your Module ID is set on powerup, and your ECOM is ready to communicate
on the network. We step through setting the DIP switch on pages 2-5 and 2-6.
Name
If you prefer to be able to set or change all Module IDs on your network from a single PC, use
the tools in NetEdit3, discussed in chapter 3.
A Name makes it easy to recognize the PLC by its function. An example of a Name is
“PumpStationOne.” The Name can be up to 32 alphanumeric characters in length. A Name
can be assigned using NetEdit3.
NOTE: Some HMI software products will not accept Names with numbers as the first character, spaces or
certain other non-alphanumeric ASCII characters. Also, your HMI product may not accept Names longer
than 16 characters. Consult your HMI product documentation about its naming conventions
