Q: Using NetEdit the EZ Ethernet/EtherPLUS is visible, but when using EZTouch software's Select Panel, it does not show up in the list.
A: NetEdit reports everything that responds to the broadcast (looking for modules), but the Select Panel button in EZTouch software filters out everything on the network that is not an EZ Ethernet/EtherPLUS adapter. It also uses IPX protocol whereas NetEdit can use both. Therefore, check the following:

Q: Getting various errors with EZ Ethernet/EtherPLUS adapter (e.g. no longer visible or disappears from the network).
A: Several temporary errors can be remedied by powering down the EZ Touch panel, removing the EZ Ethernet/EtherPLUS adapter (leaving it out for a few moments), then reinstalling and powering up. For more specific help, refer to the following specific errors and their solutions or work-arounds:

Q: Can retries and timeout values for NetEdit be adjusted to allow it to find Host Ethernet devices on much slower networks?
A: No, but we will probably include this ability in future releases of NetEdit (greater than v3.7). Currently NetEdit sends out a broadcast and waits 600 ms for devices to respond. If the devices take longer than this to respond they will be missing from his list. After the responses are gathered, NetEdit makes a list and then polls each device in the list one at a time to get detailed data, but waits only 250 ms for response from each device. If the device takes longer than this to respond some of its data may be missing. This is not a problem on a normal wired network, but can be a problem on a wireless network or across the Internet where responses can inadvertently be long and inconsistent. Also, since a broadcast is used, any device between NetEdit and the Host Ethernet modules that block broadcasts can prevent NetEdit from seeing anything.

Q: Why doesn't the ECOM use subnet mask or gateway address like the ECOM100?
A: Since the ECOM doesn't do "master"-type communications, it doesn't use the subnet mask or gateway address. Whatever talks to the ECOM will be using IPX or UDP/IP, and the ECOM simply swaps the destination and source addresses in the telegram and responds in this way, not "caring" about the subnet or gateway. However, the ECOM100 acts more like a conventional TCP/IP device. The ECOM100 has the capability to be a master and has a full-blown TCP stack inside. Thus, if it is to transmit to an IP address not on its subnet, it will, of course, transmit to its configured gateway address instead.

11-Feb-2003
Q: How many PLCs can I connect to one EZ Ethernet/EtherPLUS adapter card?
A: Six (6) is considered the limit. Anything over six is considered a "crap shoot." It might work, or it might give you trouble.

Q: What is the export classification of your products (e.g. ECCN)
A: None of our products have an ECCN. Automation Direct sells our products and they export EAR99 NLR (No License Required). ECCN is Export Controlled Classification Number and none of our products are controlled.


EZEthernet FAQ0011 (see also EBC FAQ0015; HA-TADP FAQ0001; EDRIVE FAQ0001; ECOM FAQ0008; ERM FAQ0009; WinPLC FAQ0004)
07-Feb-2003
Q: Can the MAC address be changed?
A: The MAC address is burned into the ROM of the device and is set just before it leaves the factory. There is no logical way for any protocol to change this address. Host Engineerings range for Ethernet MAC addresses is 00.E0.62.xx.xx.xx.

However, there was a bug with the old Ether32.EXE program that could change the MAC Address! If you use Ether32.EXE to update the booter using TCP/IP protocol (i.e. use the "/pi" option on the command line), then the MAC Address could be changed by accident!


EZEthernet FAQ0012
09-Jan-2003
Q: How can I configure the EZ Ethernet/EtherPLUS over the Internet?
A: Follow instructions:

  1. The EZ Ethernet/EtherPLUS adapter must have a registered Internet (TCP/IP) address.
  2. Ping your EZ Ethernet/EtherPLUS adapter using a Command Prompt: (e.g. type:      ping <your EZ Ethernet/EtherPLUS's TCP/IP Address>    and press <ENTER>).
  3. Note the average turnaround time.
  4. Select Panel in EZ Touch:

Now you should be able to configure the EZ Touch Panel from the Internet.

Q: Do Host Ethernet devices use full- or half-duplex communications?
A: Half-duplex, allowing alternating transmission in 2 directions, but not in both directions simultaneously.


EZEthernet FAQ0014 (see also ERM FAQ0014; EBC FAQ0023; ECOM FAQ0019; EDRIVE FAQ0005)
26-Mar-2003
Q: For my Ethernet network that would exceed 100 meters, is a standard hub considered a repeater so as to increase the permissible length?
A: Yes. The maximum distance per 10BaseT cable segment is 100 meters. Repeaters (e.g. hubs, bridges, etc.) extend the distance. Each cable segment attached to a repeater can be 100 meters. Thus, two repeaters can gain you a total of 300 meters distance.

EZEthernet FAQ0019
25-Mar-2004
Q: Can the EZ EtherPLUS card serve as a gateway between the PLC and a Modbus TCP/IP slave device?
A: No. Although the EZ EtherPLUS card is a Modbus TCP/IP master and can therefore talk to any Modbus TCP/IP slave, it is not a control device. The EZ Touch panel does not allow automatic control (scripting, or writing data automatically) and therefore cannot write data to the Modbus TCP/IP slave device without user intervention (i.e. pressing a button on the EZ Touch panel).

Q: Using NetEdit the EZ Ethernet/EtherPLUS does not show up in the list.
A: NetEdit reports everything that responds to the broadcast (looking for modules). Therefore, check the following:


EZEthernet FAQ0021
20-Jan-2003
Q: My EZ Ethernet/EtherPLUS adapter locks up (stops responding).
A: This is more than likely caused by the adapter getting hit by broadcasts on the network. Any broadcast packet placed on the wire must be processed by the EZ Ethernet/EtherPLUS adapter; it cannot simply ignore it. Therefore if the network has broadcast packets then this increases the opportunity for a deadlock condition between the panel and the EZ Ethernet/EtherPLUS adapter to occur simply because the adapter gets so busy trying to process them that it appears to lockup. The best thing to do is to isolate the EZ Ethernet/EtherPLUS and its ECOM(s) from the broadcast traffic.
An isolated network is highly recommended!!!

But this problem has been fixed in:

EZ Ethernet firmware v1.3.4
EZ EtherPLUS firmware v2.0.10


EZEthernet FAQ0022
24-Mar-2003
Q: Can multiple EZ Ethernet/EtherPLUS adapters be used on the same network as a DirectSOFT programming link to the same ECOM?
A: Yes, this will work. However EZ Ethernet/EtherPLUS performance will suffer considerably when you are online with DirectSOFT; particularly if monitoring data in DirectSOFT. Therefore if frequent used is needed for DirectSOFT is would be a much better idea to get a second ECOM and isolate the networks from each other.

Q: How can I install IPX protocol for my NIC?
A:  You can find instructions on how to do this for your particular operating system by going to Start --> Help & Support and searching for "Install NWLink." Below are the instructions from Microsoft for doing this on a WinXP PC. The instructions are similar for other operating systems (e.g. WinNT, Win98, WinME, Win2K).

To install NWLink IPX/SPX/NetBIOS Compatible Transport Protocol
(
1)  Open Network Connections:
       (a)  Click Start --> Settings --> Control Panel.
       (b)  Double-click Network Connections.
     NOTE:  You must be a member of the Administrators group to install protocols. Also, when IPX is installed it is installed for all your connections. If you don't want it installed for a certain connection, then right-click that connection, click Properties and, on either the General or Networking tab, clear the NWLink IPX/SPX/NetBIOS Compatible Transport Protocol check box.
(2)  Right-click a local area connection, then click Properties.
(3)  On the General tab, click Install.
(4)  In the Select Network Component Type dialog box, click Protocol, and then click Add.
(5)  In the Select Network Protocol dialog box, click NWLink IPX/SPX/NetBIOS Compatible Transport Protocol, and then click OK.

IMPORTANT: The IPX/SPX protocol is not available on WinXP 64-Bit Edition, WinVista or Win7.

Q: I inadvertently changed the IP address of my Host Engineering Ethernet device and now NetEdit cannot find it, nor can I ping it. How can I get it "back?"
A:  It can be changed using IPX protocol:

  1. If IPX protocol is not installed for your PC's NIC, then install it (see EZEthernet FAQ0027 above).
  2. Select IPX protocol in NetEdit3 and edit the IP address.

Q: What do the Ethernet Stats at the bottom of NetEdit specifically mean?
A:  These are stats that are reported up to the firmware from the hardware communication components. They are technically defined as:

Missed Fr - "Missed Frames" - A count of the packets missed due to overruns, unavailable buffers or a disabled receiver.
TX Coll
-
"Transmit Collisions" - A count of the packets which had a late collision while being received.
Lost Pkts
- "Lost Packets" - A count of the packets discarded because they were too long or too short.
Bad Pkts
- "Bad Packets" - A count of the packets which have bad CRCs (checksums).
Unknown
- A count of the packets which contain invalid symbols, extra bits or resulted in a receiver overrun condition.
TX Errors
- "Transmit Errors" - A count of the packets which could not be sent because the transmitter was unavailable for an extended period of time.
