IMPORTANT PRODUCT INFORMATION
READ THIS INFORMATION FIRST
Product: VersaMaxEthernet Network Interface Unit
IC200EBI001-AC with Firmware Release 1.20
Introduction
This document contains important information not available in any other publication; therefore, we strongly
advise you first read and then save this document. This document discusses firmware release 1.20, which
corrects the problems described in the sections “Problems Resolved in this Firmware Release (1.20)” and
“Important Operational Notes” below.
Important Operational Notes for Firmware Release 1.20
Number of Allowed Connections for Modbus Protocol Mode Reduced from 10 to 1
For the Modbus Protocol mode, the number of allowed connections has been reduced from ten to one. This is
required to facilitate the message timeout function, described below.
Addition of Message Loss Timeout Function for Loss of Communications Problems
In previous releases, if the Ethernet connection was broken or the application failed to communicate, outputs
held their last state values for a fixed time of 10 to 11 seconds, then reverted to their configured default state
values. For applications where this behavior is not acceptable, a new “message loss timeout” function has
been added to the ENIU.
Configuration of this function was facilitated by extending the use of the existing Update Timeout parameter,
found on the Consumed Exchange tab of the ENIU hardware configuration window. Starting with Release
1.2, the Update Timeout parameter has dual functionality. In EGD mode, its function has not changed. In
Modbus mode, it is now used to set a message loss timeout period. If the ENIU does not receive a valid read or
write message within that timeout period, the ENIU commands its controlled outputs to go to their configured
default state values.
During normal operation, each new read or write message resets the timer. So the Update Timeout parameter
must be set to a value 2 to 2.5 times greater than the message rate to ensure that a timeout does not occur
under normal operation. In the case where a timeout occurs due to a loss of communications, the ENIU waits
for a new Modbus connection to open and for receipt of a write message before bringing outputs out of their
default state.
Note that the Update Timeout parameter will be automatically set to 2 seconds if Autoconfiguration is used or
if a new default configuration is stored from the configuration software. Also note that if the Update Timeout
parameter is set to 0 (zero), the message loss timeout function is disabled, and the ENIU will hold its last state
for 10-11 seconds as in previous releases of the module. The range of time values allowed for the Update
Timeout parameter is 10 to 3,600,000 milliseconds. This timer operates at the Application layer.

Problems Resolved in this Firmware Release (1.20)
Outputs Hold Last Values in Modbus Mode if Application Hangs up
The problem of outputs holding their last values if the controlling application hangs up, but the TCP/IP
connection remains alive, is corrected by using the “message loss timeout”function in this release (1.20),
described in the Important Operational Notes section above. However, this also requires that you use no more
than one connection in Modbus Mode and that you set an appropriate value in the Update Timeout parameter,
both of which are described above in the Special Operational Notes section.
Outputs Hold Last Values in Modbus Mode for 10-11 Seconds if Ethernet Connection is Lost
In ENIU releases prior to Release 1.2, Outputs hold their last values for 10-11 seconds if the Ethernet
connection is broken. This behavior can be changed by using the new “message loss timeout”function,
described above in the Important Operational Notes section.
ENIU Stopped Producing EGD Exchanges if Broadcast Exchange was 256 Bytes or Greater
This release (1.20) has fixed the problem in which, in EGD mode only, the ENIU stopped producing
exchanges when it received a broadcast exchange that had a length greater than 256 bytes.
Rejection of Invalid Network Parameters
Starting with Release 1.2, certain invalid network parameters, such as IP address of zero in the local subnet
are rejected by the ENIU.
Rejection of Configuration where Consumption IP Matches ENIU IP
Starting with Release 1.2, the ENIU will reject a configuration in which the Consumption IP address is the
same as the ENIU’s IP address. This applies to unicast, multicast, and broadcast conditions.

required to configure these modules.
General Operation Notes
Power Cycle Conditions.
For both discrete and analog Output or Mixed modules, if the ENIU loses power but the Output or Mixed
modules do not lose power, the Hold Last State parameter does not work as might be expected. Upon ENIU
power loss, outputs configured for Hold Last State go to the Last State value on modules that still have power.
When power is restored to the ENIU, outputs go to the Default value. When communications are reestablished
and the ENIU receives a Write message, outputs go to the values in the ENIU’s Output Table.
Restrictions and Open Problems
Verify or Clear Operations Fail Occasionally
On rare occasions, a verify or clear operation from the programmer will fail. Retry to correct.

Quick Start Guide
1. Install the ENIU on the DIN-rail by simply clicking it into place.

Important Product Information 5
GFK-1859B
Note: The ENIU and connecting carriers must be installed on the same section
of 35mm x 7.5mm DIN-rail.
The DIN-rail must have a conductive (unpainted) finish for proper grounding.
(Refer to the heading Module Installation for information about space requirements or module
orientation, or if you are installing the ENIU in an area of excessive vibration).
2. Install the Power Supply on the ENIU.
The latch on the power supply must be in the unlocked position.
Align the connectors and the latch post and press the power supply module down
until the two tabs on the bottom of the power supply click into place.
Turn the latch to the locked position to secure the power supply to the top of the
ENIU.
Complete the power supply wiring as described in the installation instructions provided with the Power
Supply.
3. Set the IP Address - Adjust the rotary switches on the front of the ENIU using a 2.44mm (3/32in) flat
screwdriver. These switches, marked IP Address A.B.C.x / X100, X10 and X1, select the hundreds, tens,
and ones digits of the last field in the Ethernet IP address. The first three fields in the IP address, A.B.C.,
are fixed to 195.0.0. when the unit is shipped from the factory. For the last field, select any valid address
in the range 1-254. Always cycle power to the ENIU after changing the switch settings.

4. Alternate Method to set Temporary IP Address using Telnet
NOTE: This step is an alternate to Step 3 above. Be aware that the address set with this method is
temporary. It will be lost if power is cycled.
a. The ENIU and the personal computer must be operational and interconnected via an Ethernet connection.
At the computer’s DOS command prompt, type in the following, then press the Enter key:
arp –s (IP address you want to assign to ENIU) (MAC address of the ENIU) (IP address of your
computer)

6 Important Product Information
GFK-1859B
FOR EXAMPLE: arp –s 3.16.27.5 08-00-19-01-48-64 3.16.88.139
NOTE: You will not see any reply on the screen.
b. To verify that the ARP table entry was accepted, type the following at the command prompt, then press
the Enter key:
arp –a
An entry matching the desired ENIU IP address (“Internet Address”) and MAC address (“Physical
Address”) should be seen in the ARP table, with the “Type”listed as 'static.' ARP TABLE ENTRY
EXAMPLE:
Internet
Address Physical Address Type
3.16.27.5 08-00-19-01-48-64 static
c. Next, create a Telnet connection to the ENIU (Port 1) by typing in the following command at the
computer’s MS-DOS prompt, then pressing the Enter key:
telnet (IP Address) 1
FOR EXAMPLE: telnet 3.16.27.5 1
A Telnet window will appear. After several seconds, a “Connect Failed!”dialog box will appear;
regardless, the ENIU will change its IP address to the one designated in the Telnet command. (NOTE: If
it takes more than 15 seconds for the Connect Failed box to appear, the Telnet command probably didn’t
work.)
NOTE: Step 4 sets a temporary IP address that will be lost if power is cycled. To set a permanent (non-
volatile) address, use VersaPro 1.5 (or later) or Remote I/O Manager 1.5 (or later) software and “store”a
configuration containing the correct IP address. NOTE: A device will need to be configured in the
VersaPro communications setup for the temporary IP address to allow you to perform the configuration
store.
5. Connect the communications bus to the connector on the front of the ENIU. (Refer to the heading Bus
Installation Guidelines for detailed bus installation instructions.)
6. Remove the connector cover on the right-hand side of the ENIU. Do not discard this cover; you will
need to install it on the last carrier. It protects the connector pins from damage and ESD during handling
and use. Do not remove the connector cover on the left-hand side.
7. Install additional modules. Mount a module on its carrier and slide it to the left along the DIN-rail to
fully engage the connector on the adjacent carrier or ENIU. Repeat for other modules, and install the
connector cover (see Step 6) on the last carrier.

8. Configuration. A configuration can be stored by VersaPro or Remote I/O Manager software, or the
ENIU can be autoconfigured. When power is applied to the ENIU for the very first time, the ENIU will
autoconfigure the modules physically present in the I/O station, starting at Slot 1. Autoconfiguration stops
at the first empty slot or faulted module. If the autoconfiguration is unsuccessful or a new
autoconfiguration is required, it is necessary to first clear the existing configuration from the ENIU. This
is done by powering down the ENIU, disconnecting the ENIU from the first I/O carrier, and powering up
the ENIU.
Note: If the I/O station includes any additional power supplies, those power supplies must be turned on either
before the ENIU Power Supply or at the same time to assure accurate autoconfiguration.
9. Observe the Module LEDs. The LEDs indicate the presence of power and show the operating mode and
status of the ENIU. The following section discusses LED operation.
