Chapter 1: Introduction

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.

DL05/06 ECOM Modules

H0-ECOM

H0-ECOM100

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.

DL205 ECOM Modules

H2-ECOM H2-ECOM100 H2-ECOM-F

H2-ECOM100

DL405 ECOM Modules

H4-ECOM H4-ECOM100 H4-ECOM-F

H4-ECOM100

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.

1–4

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.

Ethernet Communications Modules, 3rd Edition, Rev. E

Chapter 1: Introduction

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.

Chapter 1: Introduction

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.

.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:

Ethernet (MAC) Address Module ID Name IP Address

00 E0 62 20 01 20 00 E0 62 20 01 58 00 E0 62 20 01 8D 00 E0 62 20 01 94 00 E0 62 20 01 DE 00 E0 62 20 01 F1 00 E0 62 20 01 FB 00 E0 62 20 01 F0

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

Ethernet Communications Modules, 3rd Edition, Rev. E

Chapter 2: Setup and Installation

An IP Address can be assigned to the ECOM module if your network requires one. Usually, the IP Address is required in cases where PLCs are sharing the same network with PCs, and some of the PCs are carrying out functions unrelated to PLC control. Normally, a network administrator will assign an IP Address to each device on the network. If you have a separate dedicated network for your PLCs, you can use the Module ID or a Name for each communication link. You must use an IP Address, if you are using the UDP/IP or MODBUS TCP protocol.

Use NetEdit3 to assign an IP address to the ECOM (refer to chapter 3). The module ships from the factory with an IP Address of 0.0.0.0. This is not a usable IP

Address for normal communications. It only serves as a default setting which can be changed using NetEdit3. Valid settings are 1 through 254. You do not have to change the default IP Address unless you are using the IP Address to link to your ECOM module. The default setting does not cause conflicts with other network communications.

If you change the default IP Address for linking to other network devices, you must change all four “0” fields. If any field contains the number 255 and other fields have been changed, the

module will not be recognized on the network.

Example:

Client (PC/ECOM) Subnet Mask: 255.255.0.0 Valid Client (PC/ECOM) IP Address: 192.168.50.2 Valid Server ECOM IP Address: 192.168.55.5 Valid Server ECOM IP Address: 192.168.70.15

1–254 Valid settings for Bold number ﬁelds (Do not duplicate).

2–4

WARNING: It is extremely important not to have duplicate IP Addresses on your network. If you are using the IP Address to link the ECOM to any network devices (PCs or PLCs), the ECOM must have a unique number.

Ethernet (MAC) Address

A unique Ethernet (MAC) Address is assigned to each module at the factory and will not change. It is printed on a label attached to each ECOM module. The Ethernet (MAC) Address is recognized by NetEdit3. The Ethernet (MAC) Address is a twelve digit number with no deliberate relationship to your network or functional areas of your plant. It does not usually serve as a convenient and easily remembered identifier for your ECOM.

Using Multiple Network Identiﬁes

You can use the IP Address to satisfy network requirements, a Name for PCs running HMI software and the Module ID for PLCs to share data among themselves. Using one type of identifier does not limit your use of the other identifier types.

Chapter 2: Setup and Installation

Setting the Module ID with the DIP Switch

The ECOM’s DIP switches contain eight individual slide switches, but not all of these are active. The individual slide switches are labeled 1 through 8 on the body of the DIP switch (upside down in the following figures).

You will find that the printed circuit board is labeled 0 (zero) through 7. We use the labeling on the printed circuit board in describing how to set the switch. The table below shows the meaning of each dipswitch based on the version of the module being used.

Module ID

The dipswitch numbers on the printed circuit board indicate the power of 2 represented by each slide switch. For example, switch 0 represents 20 (or 1), switch 1 is 21 (or 2), switch 2 is 22 (or 4), and so on. The following figures show the binary value of each switch in parentheses ( ).

You can use the DIP switch on the ECOM module to set the Module ID to a number from 1 to 63. Each module on a given network must be assigned a unique Module ID if the Module ID is to be used for communications. Do not use Module ID “0” for communications.

If the DIP switch is set to a number greater than 0, the software tools are disabled from setting the Module ID. The software tools will only allow changes to the Module ID if the DIP switch setting is 0 (zero, all switches OFF). The DIP switch settings are read at powerup. You can use the software tools to set the Name and IP Address even if you use the DIP switch for setting the Module ID.

WARNING: Using duplicate Module IDs on a single network will cause unreliable PLC-to-PLC communications.

H0 / H2 Series ECOM DIP Switch

If using the ECOM/ECOM100 module with Dataworx software, or the ECOM100 with IBox Communication instructions, then dipswitch 7 must be set to ON.

The Module ID equals the sum of the binary values of the slide switches set in the ON position. For example, if you set slide switches 1, 2, and 3 to the ON position, the Module ID will be

14. This is found by adding 8+4+2=14. The maximum value you can set on the DIP switch is 32+16+8+4+2+1=63. This is achieved by setting switches 0 through 5 to the ON position.

Be careful to align the female connector on the printed circuit board of the module with the male connector on the PLC mother board. Press the module into the slot until the front of the module is flush with the front of the PLC. Check the DL06 power budget to be sure that it remains within the power supply limits before installing more modules.

The DL205 system supports placement of the ECOM module in the CPU-base only, not in local expansion bases or remote I/O bases. The number of usable slots depends on how many slots your base has. The module does not work in slot 0 of the DL205 series PLCs, the slot next to the CPU. The D2-240, D2-250-1, D2-260 and D2-262 CPUs support the ECOM modules. The D2-230 CPU does not support the ECOM modules.

Before installing the module, verify power to the PLC is turned off. To install the ECOM module, line up the module’s printed circuit board with the grooves in the base and push the module until it is flush with face of the DL205 base power supply. If you feel more than moderate resistance when you push the module into the base, the circuit board may not be aligned with the grooves in the base. When the module is firmly seated in the slot, depress the top and bottom retaining clips to lock the module in place.

NOTE: When adding modules to your PLC always conﬁrm that your power budget will accommodate the added module. See the User Manual for your PLC for more information about calculating the power budget. See Appendix A for the power consumption of the ECOM modules.

DL405 Slot Choices

For PLC systems with D4-430 and D4-440 CPUs, the ECOM modules can reside in any I/O slot but only in the CPU-base. The D4-450 and D4-454 CPUs allows the installation of the ECOM module in the CPU-base or in local expansion bases. However, it is still recommended the ECOM be installed on the CPU base.

If the ECOM module is used in a local expansion base, all bases in the system must be the “-1” type bases. The valid part numbers for these bases are D4-04B-1, D4-06B-1, and D4-08B-1. The “-1” on the end of the part number indicates that the base supports specialty modules including the ECOM. The “-1” bases can be connected as local expansion bases or remote bases. They are not the same thing. Remote bases do not support the ECOM modules.

ECOM Network Layouts

The ECOM Ethernet network is a peer-to-peer network. Using Read (RX) or Write (WX) instructions, any PLC on the network can initiate communications with any other PLC on the network. A PC running our KEPDirect for PLCs software can also initiate communications with any ECOM that is on the same network, but a PLC cannot initiate communication with the PC. A PLC cannot literally broadcast to all other PLCs at the same time, but a PLC can sequence through communication connections with other PLCs on the network, one at a time.

The ECOM products inherently support two network layouts: point-to-point and star. The point-to-point layout can be used to link together two PLCs or a PC and a PLC. A hub or repeater connects multiple network capable devices into a star topology. Multiple hubs or repeaters are used to modify the star topology so that it becomes a star-bus-star topology. See the figures below and on the next page.

Network Cabling

ECOM Supports Two Standards

Two types of ECOMs are available. One type supports the 10/100BaseT cabling standard, and the other supports the 10BaseFL connection standard. The 10/100BaseT standard uses twisted pairs of copper wire conductors, and the 10BaseFL standard is for fiber optic cabling.

10/100BaseT Networks

The cable used to connect a PLC (or PC) to a hub or repeater is called a patch (straightthrough) cable. The cable used to connect together two PLCs, or a PC and a PLC or two hubs is a crossover cable. We recommend that you purchase cables pre-assembled with connectors for convenient and reliable networking.

The above diagrams illustrate the standard wire positions in the RJ45 connector. We recommend all ECOM 10/100BaseT cables to be Category 5, UTP cable.

10/100BaseT Connections

Most 10/100BaseT hubs or repeaters use a patch (straight-through) cable for connecting the network devices (PLCs or PCs). For hub-to-hub connections a crossover type cable is commonly required. The figures on the previous page show pin assignments and insulation color codes for patch (straight-through) and crossover type Ethernet cables.

UTP Cable

The ECOM has an eight-pin modular port that accepts RJ45 type connectors. UTP (Unshielded Twisted-Pair) cable is rated according to its data-carrying ability (bandwidth) and is given a “category” number. We strongly recommend using a category 5 cable for all ECOM connections.

NOTE: See page 2-14 for 10/100BaseT cable distance limitations.

10BaseFL Connections

Each module has two bayonet ST-style connectors. The ST-style connector uses a quick release coupling which requires a quarter turn to engage or disengage. The connectors provide mechanical and optical alignment of fibers.

Each cable segment requires two strands of fiber: one to transmit data and one to receive data. The ST-style connectors are used to connect the H2-ECOM-F or H4-ECOM-F module to another H2-ECOM-F or H4-ECOM-F module or a fiber optic hub or repeater.

Fiber Optic Cable

The H2-ECOM-F and H4-ECOM-F modules accept 62.5/125 multimode fiber optic (MMF) cable. The glass core diameter is 62.5 micrometers and the glass cladding is 125 micrometers. The fiber optic cable is highly immune to noise and permits communications over much greater distances than 10BaseT.

Maximum Number of ECOM Modules on the Network

The maximum number of nodes that can be connected to a 10/100BaseT or 10BaseFL network is a function of the topology used in constructing the network. Therefore, it is not possible to state an absolute maximum number of nodes that would apply in all cases.

The IEEE 802.3 specification defines the maximum node limit for an Ethernet segment in terms of the ability to detect and avoid data collisions. A “legal” network can have any number of devices provided that they can:

• Detect all data collisions that may occur during the communication process and

• Respond to these collisions appropriately.

You must take into consideration the network limitations imposed by all cabling and network devices. Consider the limitations imposed on your network if your network uses:

• A combination of cabling standards, such as 10/100 BaseT and 10Base2, or

• Intermediate devices, such as switches or routers.

Each ECOM module can be assigned a Module ID ranging from 1 to 999,999,999. Theoretically, you could have this many Ethernet modules coexisting on a single network. Other network limitations would restrict the network size before reaching this limit. For the majority of network PLC applications there is practically no limit to the number of ECOM modules you can access from the NetEdit3, DirectSOFT Programming Software or the KEPDirect for PLCs software.

There is a node limit for PLC-to-PLC communications. The network Read and Write instructions performed by the initiating (master) PLC are only capable of accessing PLCs with Module IDs of 1 through 90. This effectively sets the maximum number of nodes available for PLC-to-PLC communications at 90.

2–16

WARNING: We recommend against connecting Ethernet modules to the same network that serves as your primary ofﬁce network. While Ethernet networks can handle a very large number of data transmissions, and normally handle them very quickly, heavy Ethernet trafﬁc can adversely affect the reliability and speed of the network.

Adding Network Protocol Support to the NetEdit3 PC

You may have already set up your PC with selected networking protocols for Ethernet communications. If not, you will need to select the protocols now for communication with the Ethernet modules. We strongly recommend that you include the IPX protocol. For Windows 2000, go from My Computer on your Windows desktop to Control Panel. Double click on Network and Dial- up Connections, then double click on the desired Network Device to see the installed Protocols. If IPX is not listed among the protocols already loaded, add it now by clicking on the Install button. For Windows XP, go from Start>Settings>Control Panel. The steps are the same as Windows 2000 from this point.

Add the TCP/IP protocol if it is necessary for your application. The TCP/IP selection will give you support for the UDP/IP protocol. Also, add the IPX protocol if it is not already active.

3–4

NOTE: We strongly recommend you load IPX protocol on your PC for the connection from your PC to the Ethernet modules. Use UDP/IP in your application, if required, but also add IPX to your list of active protocols. Having IPX loaded on your PC gives you a backup for troubleshooting communication problems.

Chapter 3: Conﬁguring ECOMs Using NetEdit3

Using NetEdit3

This section steps through the features and uses of NetEdit3. We will describe the individual segments of the NetEdit3 screen and the function of each.

NOTE: Your PC-based Control software may be capable of conﬁguring the EBC module. If so, please refer to the appropriate documentation for that software product to determine the best method to conﬁgure the EBC. Depending on which software you are using, it may not be necessary to use NetEdit3.

Ethernet Communication Protocol

In the upper left corner of the NetEdit3 screen, you will find buttons labeled IPX and TCP/IP. The ECOM module understands these protocols. Both protocols are permanently resident in the firmware of the module.

When you click on one of these buttons, you are selecting the protocol you want your PC to use to communicate with the ECOM module. You are not telling the module which protocol to use, because it is using both protocols all the time. IPX is a Novell standard in widespread use, and UDP/IP is a popular protocol supported by the TCP/IP suite of protocols in your PC.

The figure to the right shows the Protocol selection buttons in the upper left corner of the NetEdit3 screen. The choice you make here tells your PC which protocol to send to the ECOM to link NetEdit3 to the module.

Some PC-based control software products may support only one of these protocols. Read the documentation for your software to be sure the protocol you select is supported.

Ethernet Address

The upper left section of the NetEdit3 screen displays the Ethernet Address of the modules currently on the network.

If modules are added or removed from the network, click on the Scan Network button to update the list. Notice that the MAC Address is the factory-assigned address that is on the permanent label on the module.

Select a specific module here by clicking on the MAC Address or by using the arrow keys. The selected module is highlighted.

NOTE: The Module window may list the MAC Addresses of devices not covered by this manual.

Module Type, IP Address and ID

The upper mid section of the NetEdit3 screen displays the Module Type, IP Address, module

ID, Name and Description of the modules currently on the network. A new ECOM will have an IP Address of 0.0.0.0, a Module ID of 0 (zero), and no Module

Name or Description. To assign or change a module an IP address, ID, name or description refer to the EBC Settings>General Information description later in this section.

Right clicking on an ECOM module listed on the NetEdit3 screen will display the window to the right. This is an alternative to using the Module Info or ECOM settings tabs (shown below) to access the module’s configuration settings. The settings are discussed later in this section.

ECOM Settings> Conﬁguration> General

Clicking the General button in the ECOM Settings>Configuration box brings up the General Settings window below.

The General Settings box allows you to assign a Module ID. Module IDs must be unique for each ECOM, but they do not have to be in sequence. The module’s DIP switches must be set to zero to allow NetEdit3 to set a Module ID. Do not use address zero for communications.

The Name field and Description field are optional. To set an IP Address, highlight the number in each of the four boxes, and overwrite the number.

Use the twelve-digit number assigned to the ECOM module by your network administrator. If you change the IP Address, do not use the number “255” in any field. Doing so will cause communication problems. The OK button sends all the entries to the module’s flash memory.

The following table summarizes NetEdit3’s Network Identifiers and their uses:

ECOM Settings> Conﬁguration> Advanced

Clicking the Advanced button in the ECOM Settings>Configuration box brings up the ECOM Advanced Settings window below.

RX/WX - Settings box in this window provides a place to make changes that affect PLC-to-PLC communications.

ACK Timeout - sets the time limit for receiving the acknowledge (ACK) response to an RX or WX instruction. The ECOM sends a message across the LAN. The acknowledge response comes back directly from the ECOM module receiving the transmission. This timeout is the maximum for transmission and acknowledgement from ECOM to ECOM across the LAN. It is not dependent on the PLC scan time.

Resp. Timeout - sets the maximum time for the receiving PLC CPU to respond to the ECOM that initiated the communication. The instruction has travelled from the initiating PLC CPU to the initiating ECOM, across the Ethernet LAN to the receiving ECOM, then to the receiving PLC CPU, and back again to the initiating ECOM. Multiple PLC scans may be required to execute an RX/WX instruction so the Resp. Timeout should allow for multiple scans. Also, communication errors may result in retries which require more time. Your response timeout setting must accommodate retries as well.

The WX/RX Retries field shows the number of times the ECOM will retry transmissions to the network.

The K- Sequence Retries field shows the number of times the backplane transmission between ECOM and CPU is to be retried.

The OK button loads the communication settings in the ECOM module’s flash memory.

ECOM Settings> Conﬁguration> Peer to Peer

This function allows you to configure the client H0/H2/H4 -ECOM(100) module to use an IP protocol packet to perform the RX/WX instruction, as opposed to a broadcast packet to locate the slave ECOM or MODBUS TCP server.

Chosing Peer to Peer: The following are reasons or conditions of when to configure the H0/ H2/H4 -ECOM(100) for peer to peer communications with a TCP/IP server device:

• To eliminate network broadcast trafﬁc when the ECOM(100) is a client executing RX/WX network instructions.

• When an ECOM(100) is an “ECOM protocol client” and needs to access other server ECOMs through a router.

• When an ECOM100 needs to serve as MODBUS TCP client

Clicking the Peer to Peer Config button in the ECOM Settings>Configuration box brings up the Peer to Peer Configuration window shown below. Any previous peer to peer configurations will be listed in the table.

The RX and WX ladder logic instructions used by the PLC allow you specify a Node (Device) Number as the slave identifer in the range of 1- 87. The Peer to Peer Configuration information is stored in the ECOM(100) module’s flash memory. This basically associates a Device Number (that is used by the RX/WX instructions) with a server’s IP address.

Clicking on the Add button in the Peer to Peer Configuration window will display the Add Device Address window shown to the right. Enter the necessary server’s network information (i.e. Device Number, server’s IP address and protocol). You can manually enter the information or you can click on the Find Hx-ECOM button to display all local ECOMs currently on the network. MODBUS TCP device’s network information will have to be entered manually. Refer to page 6- 6 for information on Port and Unit ID Numbers. Clicking the OK button adds the Device Configuration to the main peer to peer configuration screen. Be certain not to duplicate Device Numbers.

Clicking on the Find Hx-ECOM button in the Add Device Address window will display the Select ECOM window shown to the right. Highlight the server ECOM that you intend to communicate with peer to peer via the client ECOM(100) module. Then click the OK button. This will add the ECOM’s Device Configuration information to the previous Add Device Address window.

Once the module’s network information is in the Add Device Address window (previous page), click the OK button to add the information to the main Peer to Peer Configuration window. Repeat the steps to add other ECOMs to the configuration. Clicking the OK button on the main screen window writes the module(s) network information to the ECOM(100)’s flash memory.

ECOM Settings> Utils>Test CPU Access

Clicking the Test CPU Access button in the ECOM Settings>Utilities box brings up the window shown below.

The ECOM has two distinct “sides”, the network side, which contains the network configuration settings, and the backplane side, which the ECOM uses to communicate with the PLC CPU. It is possible that only one side could be operating correctly, while the other side is not. The Test CPU Access function will test the connection from your PC to the ECOM module through the network side, across the backplane to the PLC CPU and back to your PC.

ECOM Settings> Firmware

The functions in the Firmware box are used to update the selected module’s Firmware and Booter versions. The Restore Factory Settings buttons resets the selected module’s IP address, ID, Name and Description to factory defaults. Refer the sections on the next page to determine if updates are necessary.

3–12

Clicking on the either of the Update buttons opens the appropriate ECOM folder within the Images folder, which is created during the install of NetEdit3. The Images folder is located in the same folder as NetEdit3.exe. Each module folder contains the module’s firmware and boot loader files. The next section discusses keeping the firmware files up to date.

Chapter 3: Conﬁguring ECOMs Using NetEdit3

FileMenu> Live Update

The Live Update will retrieve the latest firmware and boot loader files from the Host Engineering web site and place them in the NetEdit3 Images folder that was created during the install of NetEdit3. The feature requires that you have a functional Internet connection (dial- up or broadband). If the Images folder does not exist on your PC, it will be created as part of the retrieval process.

When you click the Go! button on the Live Update window, NetEdit3 will compare the version information of the files on the Host Engineering web site against the files you have locally on your PC, and it will download any newer files. Once this process is complete, NetEdit3 will rescan the devices on your network and refresh the “F” and “B” columns next to the listed devices.

F / B / C Columns

The F, B, and C columns are provided to signify potential issues with devices on the network.

The “F” column will display an asterisk beside any device whose firmware is older than its firmware file in your Images folder.

The “B” column will display an asterisk beside any device whose boot loader is older than its boot loader file in your Images folder.

The “C” column will display an asterisk beside any device that has a configuration conflict with another device on the network. Duplicate module IDs (that are non- zero) and duplicate IP Addresses (that are not 255.255.255.255) will report as conflicts.
