1.3 Red Lion Software Tools

Red Lion supplies the "mission oriented" tools you need for every step of your project from the initial
specification, through startup, to years of trouble free operation. Configuration information flows between Red
Lion Windows, saving you time (you don't have to enter data multiple times) and dramatically reducing data
entry errors. Refer to the on-line help in the Red Lion I/O Tool Kit for complete details.

Web Server

An embedded web server within the I/O module may also be used for configuration, calibration and
maintenance of this device. Refer to Section 9 of this manual for further information.

Red Lion I/O Tool Kit

The Red Lion I/O Tool Kit is a configuration, calibration and maintenance tool for Red Lion hardware. It is the
preferred method of configuring I/O modules when the module will be an integral part of a Red Lion project
under the control of a Red Lion RTU or process controller. The Tool Kit software provides project wide error
checking and design automation features that will save you time on large projects. Further information can be
found in the I/O Tool Kit online help.

OPC or DDE

Kepware or other commercial OPC (OLE for Process Control) and embedded device communication driver
packages that support Sixnet or Modbus protocol generally provide access to Windows applications via OPC
and/ or DDE (Dynamic Data Exchange) protocols. An OPC/DDE server allows any Windows OPC/DDE client
application to access Red Lion I/O registers directly over Ethernet or serial ports.

There are two Kepware servers available: KepServer and KepServerEx. When an OPC command is received
by the KepServer, it sends the appropriate Modbus RTU protocol command over a serial port or Ethernet to
the remote station or module. The KepServerEx functions in the same manner, but it sends Sixnet Universal
protocol instead of Modbus RTU protocol. The I/O registers are referenced by the tag names assigned using
the Red Lion I/O Tool Kit Windows software.

Following these steps will make installation and start-up easier.

1. Mount the Hardware

If you purchased individual components, consult section 2 of this manual or other appropriate user manual
for information on installing them into an enclosure.

2. Connect Power and I/O
Connect AC power cables from a suitable power source to the 24V DC power supply. The DC power
connections are then attached to the Ethertrak-2 module bases as outlined in Section 4. Make field wiring
connections to the Red Lion I/O modules terminal connector strip and any peripheral equipment. Refer to
the appropriate module and remote equipment user manuals for I/O connection details.

3. Install Communication Wiring to I/O Modules
Make the necessary Ethernet, USB, or RS485 communication connections to any EtherTRAK-2 I/O
modules. Install the appropriate Ethernet, USB, and/or RS485 cabling between the Red Lion equipment
and to your master I/O polling device. Fabricate and install RS485 cables as needed to connect to other
devices.

4. Configure Network Mode and DI COM Jumpers
Detach the module from the base by unlatching the red module locking tabs, located on the top and bottom
edges of the module. Configure the network and discrete input jumpers accordingly as is detailed in
Section 3. Replace the module and push in the locking tabs.

5. Apply Power

Apply power. Observe the status (OK) LED on each unit. Typically a solid ON indicates proper operation. A
blinking LED may indicate that the unit needs to be configured. Section 8 provides details on the LED
status lights.

6. Configure Using the Web Server or I/O Tool Kit Windows Software

Application-specific configuration choices may be made by using the web server embedded with the I/O
module or through the I/O Tool Kit software.

7. Test the Hardware

Use the Test I/O window in the I/O Tool Kit software or the Web Server to verify proper I/O operation of all
Red Lion stations. Refer to the I/O Tool Kit or web server on-line help system for further instructions.

8. Configure Your I/O Master to Communicate with the Red Lion station(s)

Communication between these I/O modules and your intended I/O master is beyond the scope of this
manual.

9. If You Have Difficulty

2 Assembly and Instruction

2.1 Panel Assembly

Most Red Lion components snap onto DIN rail strips fastened to a subpanel. Two red-colored snaps, located
on the bottom of the module’s base subassembly, are available for quick and easy DIN rail mounting. One
snap allows for vertical mounting orientation, the other for horizontal mounting. The I/O Module is
approximately 5.5” high and 3.5” wide (refer to the Mechanical Dimensions diagram, Figure 2-1 below).

Arrange the enclosure layout to suit your application. Like EtherTRAK-2 I/O, other Red Lion components can
be installed in any orientation and order on your panel. The Red Lion components are typically installed
against one another, but space may be left between modules to accommodate other DIN rail mounted
components such as terminal blocks and fuse holders. End clamps are recommended to restrict side-to-side
movement. Be sure to allow ample space between DIN rails for wire ducts.

For most EtherTRAK-2 base I/O and power screw terminal sizes used on Red Lion products are M3 and can
support wire sizes of 30-12AWG. The recommended torque is 5 IN/LB.

The exception to this is the E2-16ISOTC-D I/O wiring. The screw terminal sizes are M2 and can support wire
sizes of 30-16AWG. The recommended torque is 1.5 IN/LB.

2.2 Replacing the logic module

The logic module can be removed from the base in a system that is powered on (hot-swap). The module
maybe removed and replaced with another one for troubleshooting or repair/replacement purposes. To remove
the module first open the lock tabs on the top and bottom of the module as show in the picture below. Next,
pull on the module from the middle as show in the picture below. To replace the module reverse this process.

2.3 Base Cover

The screw terminals and communication ports may be covered by the base covered. The base cover is
included with every module and must be used to comply with CE. To adjust the size of the holes for the wiring
cot out the punch-out boxes with a sharp knife. Note: Do not attempt to push the punch-out boxes with hand.

Dual Ethernet I/O Module

3 Jumper Settings

3.1 Setting the Network Jumper

This jumper sets the network configuration for the two (“dual”) Ethernet ports.

Network Mode Jumper Location
The Network Mode jumper is located on the wiring base assembly. To locate the jumper, you must first remove the I/O
module from the wiring base. To do this, you must first unsnap the two red-colored quick-lock tabs located at each end
of the module using a small flat-tip screw driver. Carefully pull the module from the base to reveal the Network Mode
jumper.

Network Mode Jumper Location

IMPORTANT: Before connecting the I/O
Module to an Ethernet network, it is
necessary to first set the Network Mode
jumper to insure that unwanted
connection paths are not created.

NOTE: The jumper is located on the base so that the replacement of a module or inadvertent change in configuration
will not adversely affect the network.

EtherTRAK®2 and Etherbus®

Pass-thru (Ethernet
Message Pass-thru)

An unmanaged switch in the module passes Ethernet traffic
between the ports. This option allows I/O modules to be
daisy-chained without the need for external Ethernet
switches.

Ring

This option allows the two Ethernet ports to act as Real-time

Ring™ switch ports. This mode should only be used if this

module will be placed in a closed ring consisting of other
similarly configured I/O modules, and Real-time Ring™
switches.
IMPORTANT: When switching to and from Ring mode you
must make sure the modules are not connected in a closed
loop. If a loop is present when ring mode is disabled it may be
adversely affect the performance of your network.

Two Networks

In this option, traffic is blocked between the two Ethernet
Ports so that the I/O module can be connected to two
independent networks. Each Ethernet port has a separate
MAC address and requires its own IP address.

Dual Ethernet I/O Module

Network Mode
This jumper sets network configuration for the two (or “dual”) Ethernet ports on the base. One of three modes can be
set:

Choose the desired mode and set the jumper accordingly. Reassemble the module subassembly to the base
subassembly. The jumper is located on the base so that the replacement of a module or inadvertent change in
configuration will not adversely affect the network.

NOTE: If the jumper is missing, the jumper setting in the base defaults to the “Two Networks” mode, because this is the
least likely to cause network problems.

Configuring the Network (“Dual Ethernet”) Mode

Using the I/O Tool Kit Windows configuration software or the web server embedded into the I/O module, access the

configuration pages and select the Ethernet configuration page. In the “Dual Ethernet Mode” drop down menu, select

the mode that matches the jumper setting that has been set in the wiring base. Section 7 of this document has additional
information on configuration.

NOTE: The default communication mode is to follow the jumper, so initial set up does not require configuration. When
the setting is set to something other than follow the jumper the setting must match the jumper setting; otherwise there
will be a conflict on the network.

3.2 Setting the DI COM Jumper

The Discrete Input Common (“DI COM”) jumper sets a select number of discrete input circuits as either “Sourcing” or
“Sinking” on certain types of modules only (as listed below). All 32 inputs are Sourcing (by default) and the first 8

channels can be Sinking (by jumper). The number of inputs affected by this setting will vary by module type:

*All 32 inputs available for Sourcing

NOTE: This jumper is not applicable on other EtherTRAK-2 I/O modules that offer individually isolated discrete inputs
(such as the E2-16DI24 and E2-16DIAC modules) where sinking or sourcing can be wired on individual input pairs.

IMPORTANT: Before connecting and powering up the I/O Module, it will be necessary to first set the “DI COM”

jumper.

DI COM Jumper Location
The DI COM jumper is located on the base subassembly. To locate the jumper, you must first remove the module
subassembly from the base subassembly. To do this, you must first unsnap the two red-colored quick-lock tabs using a
small flat-tip screw driver. Carefully pull the module from the base to reveal the DI COM jumper.

NOTE: The DI COM jumper is located on the base so that the replacement of a module or inadvertent change in
configuration from the web server or I/O Tool Kit software will not adversely affect the power wiring on the affected
inputs.

Dual Ethernet I/O Module

Determine Sinking or Sourcing Mode

The default jumper setting is sourcing (jumper to “DC–“) which is appropriate for most situations in which a positive
voltage is applied to an input to indicate an "ON" condition. Select Sinking (jumper to “DC+”) for "ON" inputs
corresponding to ground closures that require a positive reference as an opposing return connection. (See both jumper
circuits below.)

Choose the mode that fits your application and set the jumper accordingly. Reassemble the module subassembly to the
base subassembly.

Configuring the Module for Sinking and Sourcing

Once the module is reinstalled and power is applied, the module will automatically read the DI COM jumper setting and configure
the module accordingly.

If you are configuring the module from the web server, you can view the jumper setting from the “Discrete Options” configuration
page. Note that the parameter “Source/Sink mode” will display the corresponding jumper setting as “Sink” or “Source”.

If you are configuring the module from the I/O Tool Kit Windows software, in the Discrete Options configuration screen,
in the "Source/Sink mode" drop down menu, select the mode that matches the jumper setting, otherwise a conflict will
arise on the affected discrete inputs. The “Follow the Jumper” selection will tell the firmware to use the setting as it is
set in the hardware jumper. Otherwise this configuration setting should match what the hardware jumper is set to.

4 Power Wiring Alternatives

4.1 Power Requirements

Modules may be powered from any suitable DC power source of 10 to 30 VDC. Most frequently, EtherTRAK-2
I/O modules are powered from a +24 VDC industrial rated power supply such as the Red Lion ET-PS-024-02
(2 Amp) or ST-PS-024-05 (5 Amp).

4.2 Current Requirements

To calculate the supply current requirements, add the wattage required for the Red Lion and other units in use.
Next, divide the total wattage by the DC power source voltage. Then, add any current needed for user
instrumentation loops and output loads.

4.3 Power Wiring

There are five screw terminals associated with powering the module:

Dual Ethernet I/O Module

4.4 Etherbus PoE Option

Etherbus I/O provides the capability to utilize Power over Ethernet (PoE) to power the I/O module and associated
instrumentation directly from the Ethernet cable.

Etherbus PoE Power – PoE power supplied to Ethernet port #1 will power the module’s intelligence, communication and
input channels as well as supply +24 VDC power for external loads. Note: A jumper is required from screw #2 to screw #6
to power outputs from the PoE power source. When the PoE supply is used and power provided, an LED light on the I/O
module will be lit to confirm the connection.

Uninterruptible Power Protection – Here’s an innovative idea: Supply backup power from a central location to each
distributed Etherbus I/O module using a single Etherbus Fieldbus cable.

This PoE supply provided by an independent power supply will keep the module communicating and even power critical
instrumentation in the event of a local power failure. Apply local (primary power to screw terminal #6 (Power 1+) to
power all module functions. The backup power will not attempt to operate outputs but will keep communication
running so that input status remains available in the event of local power failure. Use power from the power output

Dual Ethernet I/O Module

5 Module Wiring / Screw Terminal Assignments

5.1 Screw Terminal Guidelines

The screw terminals used on the E2-BASE-1 can accept 30 to 12 AWG wire. The screw size is M3 and the recommended
torque is 5 IN/LB.

The screw terminals used on the E2-BASE-TC-1(used in E2-16ISOTC-D only) can accept 30 to 16 AWG. The screw size is
M2 and the recommended torque is 1.5 IN/LB.

5.2 Typical I/O Wiring

The sample wiring diagram below is mostly applicable for the combination I/O modules (E2/EB-MIX24880-D and E2/EB­MIX24882-D). The I/O wiring for discrete and analog inputs is representative of most other I/O modules. Isolated I/O
wiring used in the E2/EB-16DI24-D, E2/EB-16DIAC-D and E2/EB-16DI24-D are also included.

NOTE: The upper and lower screw terminal assignments for the E2-MIX-24882-D are shown in this diagram as an
example. For detailed information on Screw Terminal Assignments for this and all other module types, consult the tables
below or the help files in either the I/O Tool Kit software or the module’s web server.

Dual Ethernet I/O Module

6 I/O Functions

This section describes the characteristics of the various I/O functions found in this family of I/O modules. Each
topic in this section identifies which modules in the EtherTRAK-2 I/O product family include each feature.

6.1 High Density Discrete Inputs

Applicable to: E2-MIX24880(9-24), E2-MIX24882, E2-MIX20884 (5-20), E2-32DI24

Standard high density discrete inputs accept input voltages in the range of the specified power supply voltage
(10 to 30 VDC, 5-30 VDC on MIX20884) and are referenced to the power return (-) to simplify field wiring.
These inputs are the “sourcing type” which means they indicate an ON condition when a positive voltage
source, above the threshold level is applied to them. These inputs may be filtered to make them immune to
short duration voltage spikes or mechanical contact bounce by configuring them for “Slow Response”, which is
approximately 6 ms.

Discrete Input Range 10 – 30 VDC

6.2 Sourcing/ Sinking Input Option

Applicable to: E2-MIX24880 (1-8), E2-MIX24882, E2-MIX20884 (5-12), E2-32DI24

The first eight discrete inputs (terminals 11 – 18, 17-24 on MIX20884) may be configured as sourcing inputs
(ON when positive voltage is applied) or sinking inputs (switch closures to ground). There is a selection jumper
in the module’s base that is easily accessed by unplugging the logic module and changing the DI jumper (refer
to “DI COM Jumper Setting” in section 3 of this manual and follow the directions). Once sink/source is properly
configured for “DC-“ or “DC+”, the module’s firmware performs a consistency check to verify that the hardware
and software selections match. When the module is configured for “Follow Jumper” the module’s firmware will
take on the state of the jumper.

6.3 Low Threshold Inputs

Applicable to: E2-MIX24880, E2-MIX24882, E2-32DI24, E2MIX20884(5-12)

The first group of eight inputs may also be modified to transition at a threshold voltage lower than the factory
setting of 9 volts. This is accomplished by soldering a resistor into the wiring base which is located alongside
the DI COM jumper.
NOTE 1: This modification is recommended for advanced users only. Please contact Red Lion Technical
Support regarding details for this modification.
Note 2: Isolated DI channels 1-4 are only low threshold channels

6.4 Isolated Discrete Inputs

Applicable to: E2-MIX20884 (1-4), E2-16DI24, E2-16DIAC

These inputs utilize two screws per input channel so that each input is isolated from all other channels and the
module’s internal circuitry. Except for the isolation characteristic, these inputs have the same characteristics as
the high density inputs, including the counter functionality.

EtherTRAK®2 and Etherbus®

Pulse Accumulator

Up Counter

16 bit (or 32 bit) upward accumulator of input pulses.

Run Time

Run Time Sec

This is the On-time Timer feature that counts the time the associated input is
in the ON state. Output is in Seconds.

Run Time Min

This is the On-time Timer feature that counts the time the associated input is
in the ON state. Same as above, except the output is in Minutes.

Pulse Rate
Timing

These 16 bit registers will record the pulse timing for the following timing
intervals: 0.1 sec (100 ms), 0.2 sec (200 ms), 0.5 sec (500 ms), 1 second, 2
seconds, 5 seconds, 10 seconds, 30 seconds, or 60 seconds.

ON Pulse Width
Time in ms between consecutive leading (OFF to ON) and trailing (ON to

OFF) edges.

OFF Pulse Width
Time in ms between consecutive leading (ON to OFF) and trailing (OFF to

ON) edges.

Notes regarding pulse width measurements:

1. Pulses longer than the maximum size allowed by the register will result in
an overflow condition (full scale 16-bit value equal to 65535).

2. Pulses shorter than 1ms will not be accurately detected resulting in
erroneous values.

3. If no edge is ever detected by an input, the result will read as $0000.
Timing only begins when an edge is detected.

6.5 Discrete Input Counter Feature

Applicable to: E2-MIX24880, E2-MIX24882, E2-MIX20884, E2-32DI24, E2-16DI24, E2-16DIAC

Counter Modes: Count Up, Pulse Timing and Pulse Rate

To enable counters (16 registers: AX8 though AX23) or (12 registers AX8 through AX19 on E2-MIX20884), using the I/O
Tool Kit or the module’s web interface, go to the "Discrete Options" screen and check the "Enable Counters" checkbox.
Go to the "Analog Input Channels" screen, select a cell and a pull down menu is displayed. Select the mode of operation
for each counter function. In all 16 bit upward counting modes, the analog input register increases from 0  32767, then
wrap around to -32768  0.
If the “Report all Counters as 32 Bit Values” checkbox is selected (Analog Options screen),
the long integer input register (consecutive pair of analog registers) increases from
0 2,147,483,647, then -2,147,483,648 and back to 0.

The menu selections for each of the available counter modes and their default resolutions are:

6.6 High Speed Counters

Applicable to: E2-MIX24880, E2-MIX24882, E2-MIX20884, E2-32DI24, E2-16DI24

High speed counters can be enabled on the first two to four channels. In the web server or I/O Tool Kit
software “Discrete Options” configuration page, check “Enable high speed counters on Channel 1” and/or
Channel 2 to enable these modes. This special mode functions in the same manner as the discrete input count
feature for the corresponding input, except that the maximum count rate for the first and/or second input is
increased to 50 kHz (2kHz on the E2/EB-16DI24-D).

Note 1: On the E2/EB-MIX-24880-D and E2/EB-32DI24-D modules only, the first high speed counter is
connected to two isolated input screw terminals (43 and 44) and screw terminal 11 is disabled. If the high
speed counting option is not selected, then the pulses are counted from the ordinary discrete input screw
terminal in the manner typical of all other input channels. This isolated channel is capable of counting up to
50kHz (3,000,000 pulses/min).

Note 2: On the E2/EB-16DI24-D module only the first two isolated high-speed counters are capable of counting
up to 2kHz (120,000 pulses/min).

6.7 Slow/Fast Response for All Discrete Inputs

In the web server or I/O Tool Kit software, select “fast response” to use no input filtering. DC input changes as
fast as 1 ms will be detected. Selecting the “Slow response” setting will tell the module to look for stable inputs
for approximately 25 ms. This setting will filter contact bounce, which often happens while counting mechanical
switch closures in noisy environments.

6.8 Combination Discrete Inputs/Outputs

Applicable to: E2-MIX24880(17-24), E2-MIX24882 (17-24), E2-MIX20884 (13-20)

The last eight discrete I/O has both input and output capabilities at the same time. Output functionality for a
given channel may be individually enabled in the “Feature” column of the Discrete Options configuration
window. For compatibility with I/O drivers that write I/O in fixed blocks, all eight Y (output) registers are always
assigned. Only outputs that are enabled may be turned ON. Other output values will be masked in the I/O
module.

All eight channels are always active as inputs. Channels that do not have their output function enabled may be
used as inputs. For channels configured as outputs, the input functionality may be used to detect faults in the
corresponding outputs.

Important Note: The supply voltage used to power input devices connected to the combination I/O channels
must match the supply voltage used to power the I/O module to avoid leakage paths or damage to the I/O
circuitry on these modules. It is recommended that the same power supply be used to power the I/O module
and input devices connected to these special I/O channels. If a voltage source is applied to the eight
combination I/O channels that exceed the voltage supplied to the rest of the I/O module, unintended power
paths may result.

Dual Ethernet I/O Module

6.9 High Density Discrete Outputs

Applicable to: E2-32DO24

High density discrete outputs provide:

A. Individual maximum outputs rated for 1 Amp per channel, 8 Amps total per module. Short duration

inrush current as high as 2 Amps is permissible.

B. Sourcing switched output power at the voltage supplied to the module’s supply voltage input (less a

nominal voltage drop in the output’s power switching device).

C. Current limiting is not provided on the outputs of this module.

6.10 Isolated Discrete Outputs

Applicable to: E2-16DO24

Isolated discrete outputs provide:

A. Individually isolated outputs rated for 1.0 Amp per channel at temperatures up to 60 °C. (0.75 Amps at

higher temperatures). Current limiting provided on each output.

B. Two screw terminals, isolated from all other outputs and the module’s internal circuitry, for each

channel

C. Any voltage up to the rating of the module may be applied to each individual output.

6.11 Isolated Output Relays

Applicable to: E2-16DORLY

Isolated discrete output relays provide:

A. Individually isolated outputs rated for 1.0 Amp per channel.
B. Two screw terminals, isolated from all other outputs and the module’s internal circuitry, for each

channel.

C. Any voltage up to the rating of the module may be applied to each individual output.

6.12 Time Proportioned Outputs (TPO)

Applicable to: E2-MIX24880, E2-MIX24882, E2-MIX20884-D, E2-32DO24, E2-16DO24

The discrete output channels in all EtherTRAK-2 I/O modules are capable of functioning as time proportioned
outputs. Time proportioned outputs pulse ON and OFF with a duty cycle proportional to an analog value
stored in a corresponding analog output register. TPO outputs are a low cost way to get smooth proportional
control of heaters and other process variables. Typically, TPO analog output registers are assigned to the
output of PID or other control logic in an ISaGRAF or other control program. Use the module’s web interface or
the I/O Tool Kit software to set pulse cycling as fast as 10 ms or as slow (many minutes) as your system
dynamics require. Each output may be individually configured as a TPO or ordinary discrete output.

In this example, TPO #1 has a 10 second cycle time and the analog value is 3276 (10% of full scale, which is
typically 32767). The output will be ON for 1 second and OFF for 9 seconds during each 10 second period.

TPO #2 has a 2 second cycle time and the analog value is 26214 (80% of full scale). The output will be ON for

1.6 seconds and OFF for 0.4 seconds during each 2 second period.

TPO #3 has a 2 second specified cycle time, an analog value of 820 (2.5% of full scale) and a minimum
ON/OFF time of 100 ms. Since the minimum cycle time is 100 ms and the calculated ON time is only 50 ms,
the cycle time is readjusted by a factor of 2 to maintain the time proportion. The output will be ON for 100 ms
and OFF for 3.9 seconds before repeating.

Note: Non-integral remainders of time are carried forward to the next cycle, to maintain long-term accuracy. (In
Example TPO #3, the below minimum time is carried forward to the next time cycle. When the below minimum
value is calculated, no ON time is set for that cycle.

6.13 4-20 mA Analog Input Wiring

Applicable to: E2-MIX24880, E2-MIX24882, E2-MIX20884, E2-32AI20M, E2-16AI20M, E2-16AI8AO

The analog input channels accept 4-20 mA signals from a variety of devices and are protected by self-resetting
current shunts to prevent shunt overheat/damage. One screw terminal is provided for each input signal. All
analog inputs return to a common ground (terminal 8 or 6 depending on model). Refer to illustration: Base

Power & Communications Wiring Diagram in Section 4.

Open Loop Detection on 4-20 mA Inputs

This module can detect and report an open instrumentation loop on its analog inputs. By allowing the module
to report a negative value if the current falls below 4 mA, low limit logic in your DCS, PLC, RTU or computer
can signal the loss of current.

To enable this feature, go to the web interface’s “Analog Input Channels” configuration screen and select the
corresponding “Feature 1” column. A dropdown menu will appear. Select the
“– Below 4 mA” setting for each desired channel. Click on the Help button for further information.

6.14 Isolated Analog Inputs

Applicable to: E2-16ISO20M

The analog input channels accept 4-20 mA signals from a variety of devices. The inputs are isolated to prevent
ground loops and reduce inter-channel noise.

6.15 Voltage Range Analog Inputs

Applicable to: E2-32AI10V

The input range on modules that have voltage range inputs is 0 to +10.0 volts. The high 16 bit resolution of the
inputs generally permits adequate reading resolution for lower voltage input signals.

6.16 High Speed Analog Inputs

Applicable to: All modules with analog inputs

The first two analog inputs on all modules with non-isolated analog inputs may be configured as high speed analog
inputs. Analog input channels configured in this manner will update as fast as 1 ms but at the expense of having only 10
bits of reporting resolution.

Note: By default, analog inputs integrate their 16 bit reported results to provide outstanding noise rejection.
The scan time of these 16 bit inputs will vary with user configuration settings.

6.17 Analog Outputs

Applicable to: E2-MIX24882, E2-MIX20884, E2-8AO20M, E2-16AI8AO

Analog outputs on all applicable I/O modules in this product family have a 4-20 mA output range and may be
incremented (varied) with a full 16 bit resolution corresponding to the value in the associated analog output
(AY) register.
Note: Analog outputs on the E2-MIX20884 have a software selectable range of 0-20 mA, 4-20 mA, and 0-10
VDC.

6.18 RTD Inputs

Applicable to: E2-10RTD

The RTD inputs are applicable on the 10 channel RTD module. A 2 or 3 wire, 100 Ohm platinum resistance
temperature detector may be used to measure temperature.

6.19 Thermocouple and mV Inputs

Applicable to: E2-16ISOTC

The thermocouple and mV input range is 250mV. Each channel may be configured as a thermocouple or mV
range input via software (Tool Kit and/or web browser). The thermocouple types supported are
J,K,E,R,T,B,C,N,S.

Four cold junction compensation (CJC) temperatures are provided in the module to determine screw terminal
temperatures of all 16 channels. Each CJC temperature sensor is positioned underneath the screw terminals
and measures the temperature of four screw terminals. These temperatures can be read using Sixnet or
Modbus protocol at AI:16 – 19 (3:0017-3:0019). The first sensor (AI:16) measures the screw terminal
temperature of channels 1-4 (AI:0-3). The second (AI:17) measures the screw terminal temperature of
channels 5-8 (AI:4-7). The third (AI:18) measures the screw terminal temperature of channels 9-12 (AI:8-11).
The fourth (AI:19) measures the screw terminal temperature of channels 13-16 (AI:12-15).

With firmware version 01.24 or higher the cold junction compensation temperatures reported are redundant
and provide error reporting. If any of the CJC sensors fail, report an inaccurate temperature or valid
temperature cannot be ascertained the module will fall back to the linear average of the remaining sensors, the
last known good value or 25°C depending on the failure state. This way the thermocouple channels will always
report the most accurate value possible even if one or more all the CJC temperature sensors fail. The four
failure states, the error reported and the corresponding fallback state are defined below.

GOOD (measured screw terminal temperature): In this state there are no error conditions found. All the
CJC sensors (AI:16-19) will report only the measured temperature.

DEAD (-1000): In this state the module firmware has determined that one or more CJC sensors are
non-responsive to communication polling. In this state the sensor(s) reported temperature value will
change to -1000. When the sensor is in the DEAD state the module firmware will substitute the linear
average of the remaining GOOD CJC sensors on that module for the DEAD sensor. The substitution
will ensure the temperature reported on the associated thermocouples is still accurate even though the
CJC sensor is not working.

Dual Ethernet I/O Module

FAULTY (-2000): In this state the module will determine if the CJC sensors are reading realistic values.
If one or more of the CJC sensors are reporting unrealistic temperature values then the value reported
in the analog registers will be -2000. The valid temperature range is hard-coded at -50 to +100°C
(outside the modules operating temperature with some overhead to account for ambient temperature
fluctuations). When the CJC sensor is in the FAULTY state the module firmware will substitute the
linear average of the remaining GOOD CJC sensors on that module for the DEAD sensor. The
substitution will ensure the temperature reported on the associated thermocouples is still accurate even
though the CJC sensor is not reporting the correct temperature.

QUESTIONABLE (-3000): This condition determines if one or two sensors don’t agree with the other
sensors by comparing each CJC temperature sensor with adjacent sensors. If the CJC sensor differs
by 10°C or more from an adjacent CJC sensor it is considered QUESTIONABLE and the reported value
will be -3000. When the sensor is in the QUESTIONABLE state the module firmware will substitute the
linear average of the remaining GOOD CJC sensors on that module for the DEAD sensor. The
substitution will ensure the temperature reported on the associated thermocouples is still accurate even
though the CJC sensor is not reporting the correct temperature.

INDETERMINATE (-4000): When none of the CJC sensors can agree on the temperature reported, the
temperature on all the sensors will be -4000. This condition may occur if all the sensors are in a
QUESTIONABLE state or two sensors are reporting a bogus temperature. This is a multiple failure
mode, which must be INDETERMINATE for functional sensors. DEAD or FAULTY sensors will continue
to report that state. When a CJC sensor is determined to be INDETERMINATE the module firmware
will substitute the CJC sensor value with 25 degrees C when the module is initialized on power-up or
the last known good value. The substitution will ensure the temperature reported on the associated
thermocouples is as accurate as possible even though the CJC sensor is not reporting the correct
temperature.

Dual Ethernet I/O Module

6.20 Watchdog Output

Applicable to: All I/O modules

A microprocessor in the module continuously monitors several user-selected system functions. Additionally, an
independent CPU watchdog microprocessor in the module also monitors the main CPU and can be used to
indicate a failure of the main CPU. The watchdog options are (as selected in the web interface or I/O Tool Kit
software):
Power 1 Failure
Power 2 Failure
PoE Failure (Not valid on all modules)
Ethernet Ring Failure
Watchdog CPU Monitor

The default state of the Watchdog Output (screw terminal #9 or #7 on the I/O module’s wiring base, consult
base silkscreen or Section 4.5) is ON (True). If an error condition in any one of the user-selected parameters is
detected, the Watchdog will output an OFF (False) state.

The default watchdog time period is 3 seconds, and may be set as high as 65 seconds to allow for telemetry
equipment or application-related program delays. The timer period selected will apply individually to each
watchdog function selected.

6.21 Heartbeat monitor

Applicable to: All I/O modules

The heartbeat monitor is a software selection in the “Watchdog/Heartbeat Monitor” configuration page. When
the heartbeat timeout option is selected the module firmware will monitor a discrete register of choice (virtual or
physical) for a heartbeat toggle. When a heartbeat toggle has not been received on the given heartbeat
register within the given Heartbeat Timeout period the module can be configured to drop outputs (virtual and/or
physicals). This can be used as a failsafe incase the Controller, RTU, or SCADA system writing the outputs to
the EtherTRAK-2 modules fails. Please see the Tool Kit or web user interface help for more information on how
to configure this feature.

7.1 Dual Ethernet Mode Configuration Alternatives

Use either the web server within the module or the I/O Tool Kit Windows-based configuration tool to configure
the two Ethernet ports.

NOTES:

1. The Dual Ethernet Mode selected in this option must match the jumper setting in the base. Refer to Section 3
“Jumper Settings”, “Network Jumper Setting” in this document.

2. If the jumper is missing, the setting in the base defaults to the "Two Networks" mode.

3. The red alert LED on Dual Ethernet module will blink if the configuration setting mismatches the

hardware jumper setting.

4. The default state of this configuration option is “follow the Jumper”, so the initial set up can be done with

out the configuration of the Red Lion I/O Tool Kit.

In the Ethernet configuration screen, and choose one of these four options that is appropriate for your
application (refer to the Help files for additional configuration information):

Ethernet Passthru

An unmanaged switch in the module passes Ethernet traffic between the ports. This option allows I/O modules
to be daisy-chained without the need for external switches.

Ring Switch

This option allows the two Ethernet ports to act as Real-time™ ring switch ports. This mode should only be
used if this module will be placed in a closed ring consisting of other similarly configured I/O modules, and
Real-time Ring™ switches. Note: closing the ring when this mode is disabled will adversely affect network
communications. Close the ring only after this mode is configured, open the ring before disabling this mode.

Two Networks

In this option, traffic is blocked between the two Ethernet Ports so that the I/O module can be connected to two
independent networks. Each Ethernet port will require its own IP address.

Follow the Jumper

When this option is selected the communications mode will follow the state of the network mode hardware
jumper on the base. The alert LED will not blink because of a jumper mismatch in this mode.

Dual Ethernet I/O Module

7.2 Communication Ports Overview

The EtherTRAK-2 I/O modules’ wiring base subassembly has the following communication ports and
connectors:

NOTE: EtherTRAK-2 I/O includes two Ethernet RJ45 ports. Note that for modules with the Etherbus option
(EB-), use “PoE ETHERNET 1” port when bringing power from the Ethernet fieldbus cable into the module
(refer to Section 4 “Power Wiring Alternatives”).

Ethernet Port

A 10/100BaseT dual Ethernet ports are found on all units. Standard RJ45 connectors are provided with
standard 802.11 pin-outs. These ports have fixed unique MAC addresses. The IP addresses can be set with
the Red Lion I/O Tool Kit software or through a web browser. Further details are available in the I/O Toolkit
documentation or the web browser documentation.

Use data-quality (not voice-quality) twisted pair cable rated category 5 with standard RJ45 connectors. For
best performance use shielded cable. These modules have an auto-crossover feature and may be connected
with either straight through or cross-over type cables.

The protocols supported are different depending on how you are using the port. When the module is used in a
slave mode UDP/IP and TCP/IP protocols maybe used. When using the I/O transfer feature in the module
(master mode) only the UDP/IP protocol may be utilized.

USB Port

The USB port is intended for configuring the module only. It is possible to make I/O requests through the USB
port in Universal (native) protocol. This port may not be configured as a Modbus port.

RS485 Port
This port is found on the base for all EtherTRAK-2 I/O Modules. It provides a RS485 (2-wire, half duplex only)
connection to other RS485 equipment. Screw terminals are available for RS485+, RS485-, RS485 GND and
RS485 Termination.

In order to assure proper communication, you should connect (+) to (+) and (–) to (–) between units. It is highly
recommended that you tie the signal ground to an appropriate ground (if available) between all RS485 units.
Make sure to use a good quality communication cable with three conductors (twisted is preferred) plus a
shield. To prevent ground loops, the shield should be connected to chassis ground on only one end of any
cable run.

Note: If you have existing wiring that has only two conductors and a shield, you can use the shield to connect
the signal grounds between stations. This is not optimal (especially for long cable runs) but should work in
most situations.

Dual Ethernet I/O Module

The RS 485 port is not isolated (with the exception of the E2/EB-10RTD-D and E2-MIX20884-D), therefore you
must use a common power ground between stations in order to connect the 485 signal grounds. Some
applications make use of longer distances where a common ground may not be possible. When long distance
connections are used, it is highly recommended that you use an optical isolator between devices without a
common ground to assure proper, problem free operation.

RS485 Termination: All these units have RS485 termination components (150 ohm resistor and a 0.1 F
capacitor connected in series) already inside. To terminate your RS485 network on an EtherTRAK-2 I/O
Module, just jumper the “RS485 –“ (terminal 3 ) to the “RS485 TERM” (terminal 5). Make sure to use the same
type and size conductor as already used for your RS485 minus (–) connection. It is recommended that both
end stations of your RS485 network be terminated. Avoid terminating more than two stations. Note: The E2­MIX20884-D uses a termination jumper (see the RS485 jumper topic in section 3.3).

NOTE: EtherTRAK-2 I/O modules can act as Ethernet to RS485 converters and “Passthru” (pass through)
Modbus or Sixnet messages from Ethernet to RS485. In this “Passthru” mode, these modules do not convert
protocols. If a module’s serial port is configured for Modbus Passthru mode, then you must communicate to the
gateway over Ethernet with Modbus/TCP or Modbus/UDP. If the module’s serial port is configured for Sixnet
Passthru mode, then you must communicate to the gateway over Ethernet with the Sixnet protocol.

7.2.1 RS-485 Modes of Operation

The EtherTRAK-2 I/O Modules can be configured have the following modes of operation that can be
configured with the web server or the I/O Tool Kit Windows software:

8 EtherTRAK 2 Status LED’s

8.1 EtherTRAK-2 LEDs

Every EtherTRAK-2 I/O module has an array of LEDs on its front panel. These LEDs can be useful for system diagnostics.
These LEDs can be observed in the following states:

8.2 Power LED Indication

Each module has 3 green Power LED’s which are Power 1, Power 2, and PoE. These LEDs are associated
with the 3 possible power sources of the EtherTRAK 2 I/O module. If a power supply is connected to the
associated screw terminal, the corresponding LED will be ON. In the case of the PoE LED, the PoE option
must be populated in the module and the PoE must be injected in the first Ethernet port for this LED to
illuminate.

EtherTRAK®2 and Etherbus®

Full OFF

Everything is OK.

2 ON Blips repeating

Bad configuration data has been loaded to the module. Try re-loading the
configuration.

3 ON Blips repeating

Hardware DI jumper does not match loaded configuration.

1 OFF Blip repeating

Could not open configuration file (file corrupt in memory).

2 OFF Blips repeating

File System Fatal Error (corrupt flash memory).

3 OFF Blips repeating

Fatal Hardware Failure.

ON Solid

The OK LED will be in a steady ON state when both P1 and P2 power inputs
are powered and that all configured rings have continuous ring integrity.

OFF Completely

The OK LED will be OFF if either P1 and/or P2 is not powered, or if any one
of the active rings for which this switch is a member of encounters a segment
failure.

Blinking

To verify communication and target switch selection, you can request the
module to “wink” (10 blinks/sec) its OK LED to visually identify the unit. This
function is controlled through the Windows configuration and maintenance
software tools.

Blinking

A blinking LED (500 ms ON, 500 ms off), is an indication if ring is incomplete,
but ring ports see an adjacent ring partner.

Blip

An LED Blip (100 ms ON, 900 ms OFF) is an indication that there is a missing
ring partner.

8.3 Alert LED Indication

There is a single ALERT OK which is red in color and is used to display critical errors in the module. The
ALERT LED has the following behavior:

8.4 OK LED Indication

There is a single OK LED which is green in color and is used to display the status of the module. It has the
following functions:

8.5 Ring LED Indication

The “Ring” LED that is illuminated if the Ethernet ring is closed (complete Ethernet ring) and not illuminated if a
ring is not configured. Other active ring conditions are as follows:

EtherTRAK®2 and Etherbus®

OFF Completely

Unlinked / Disconnected

ON Solid

Linked (either 10/100 speed)

Blinking

Linked and activity is present.

Discrete Outputs

Discrete Outputs each have a single associated LED which is green in color.
This LED is ON when the output is ON and off when the output is OFF.

Discrete Inputs

Discrete Inputs have a single LED associated with each channel which are
green in color and have the following behavior:

OFF Completely

Input is OFF

ON Solid

Input is ON

Blinking

When the frequency of an input (such as a counter signal) is increased, the
LED will follow the input state up to approximately 20Hz, and will stop
increasing its blinking rate further. This prevents the scan rate of the LED’s
from falling lock-step with the input frequency which could result in erratic LED
behavior or patterns in the blink rate. This state doesn’t apply to relay
modules.

ON Solid

This will be on solid if the read value is between 4 mA and 20 mA (zero and full scale) or when
the RTD, thermocouple (burnout disabled) or millivolt is detected.

Blinking

This LED will be blinking if the value is between 1 mA and 4 mA, or greater that 20 mA (outside
the normal operating range). Please note that calibration settings may alter the exact threshold
for this state. Note: This state does not apply to the RTD, thermocouple or millivolt modules.

Off
Complet
ely

In 4 to 20 mA channels when the value is less than 1 mA. In RTD temperature channels when
the RTD is not present/functional or the channel is disabled. In thermocouple channels the
burnout is detected. In millivolt channels no signal is detected.

The LED’s are green in color and have the following behavior.

8.7 TR/RD Activity Indication

Depending on the option selected by the user, the TD / RD LEDs indicate activity. The LED microcontroller will
pulse stretch an indication that data has been received or transmitted. The choices for the user configuration
are:

A. Any serial port (default).
B. USB port
C. RS485 port

8.8 Discrete LED Indication

Discrete LEDs are status indicators for physical outputs or inputs based on corresponding binary tags as
defined below.

8.9 Analog Input Status

The 4-20 mA, RTD, thermocouple and millivolt analog inputs have LED’s that correspond to the following
configuration:

9 Configuring EtherTRAK-2 I/O Modules

9.1 Web Server Overview

EtherTRAK-2 I/O modules include an embedded web server. This is the primary and recommended means for
configuring I/O modules as stand-alone, independent devices ready to communicate with I/O polling masters
(process controllers). Users can use a standard web browser to access web pages to configure and maintain
the module and to validate changes.

Features include:

o Communications Options
o I/O Configuration
o Maintenance and Monitoring
o Analog Calibration
o Advanced Tools
o Password Security
o User Documentation

Access the web server using any PC with an Ethernet communications port and plug into an Ethernet port on
the EtherTRAK-2 base. Please note that security options, including disabling the web server altogether, may
be set using the I/O Tool Kit Windows software. Access the web server by simply pointing your browser to the
IP address of the I/O module. Example: 10.1.0.1

Note: Recommended web browsers are Internet Explorer, Mozilla Firefox and Chrome. When using Internet
Explorer please disable native XMLHTTP by going to ToolsInternet OptionsAdvanced.
Note: A load through the Red Lion Tool Kit must be done once or I/O channels will not work.

9.2 Setting the IP Address

The default IP address, as shipped from the factory is: 10.1.0.1
Change the IP address by accessing the web server pointed to the current IP address. You can also change
the IP address using the I/O Tool Kit software, via the Ethernet port or the USB port.

9.3 Audit Trail Change History

View the configuration changes in the View Audit Trail window. This will show a list of all configuration changes
made in the web browser. This information includes what configuration changes were made, the new and old
value, when they were changed and by whom

9.4 Adding User Documents to the Web Server

You may add your own project documentation to the web server in the I/O module. We recommend indexing
your files (documents) from a single web page named: appl_doc. These web pages may be in a number of
common formats such as .html, .shtml, or .pdf. The web server will search for this file and, if found, will
automatically add a link to your documentation onto the main menu where it will be easily found by the user.

Web pages and associated files, such as graphics, will be stored in Flash memory in the wiring base. By
storing this information in the wiring base, it will continue to be found (along with all the configuration
information) if a module is replaced. There is approximately ½ Megabyte available for user documentation. The
available size may vary when upgrades to the firmware or factory supplied web pages are updated. Additional
memory may be available as a special order item.

Your own documentation pages may be uploaded into the module’s wiring base. Refer to the online help files
in the configuration tools for further details.

9.5 Sixnet I/O Tool Kit Software

As an alternative to configuring I/O modules with their embedded web server, the Red Lion I/O Tool Kit
Windows software may be used. The Windows software is strongly recommended in situations in which
multiple devices (RTUs and I/O modules) will be interconnected in a coordinated system. The Tool Kit software
coordinates and automates many aspects of project design including sharing I/O tags between I/O modules
and the process controllers that poll them, and project-wide global error checking.

Refer to the online help within the Tool Kit for more information on using this software. Install
from Sixnet website.

10 EtherTRAK-2 Module to Wiring Base Keying

This section is recommended for ADVANCED USERS ONLY that are in need of utilizing an existing wiring base with a
different module than as originally received. Wiring bases shipped with I/O modules are pre-configured with their
alignment keys in the appropriate position for that type of I/O module.

The EtherTRAK-2 module is secured to the base over two posts utilizing a keyed interface with retaining clips. The
diagram below shows different combinations of the keying device in order to accommodate different modules. The
purpose of the keys is to prevent accidental insertion of an incorrect module, thus preventing possible damage to a
module or other equipment. Should it be required to use the existing base with a different module, it is possible to
change the keying interface per the following instructions.

When changing to different modules, it is recommended to remove all wiring from the base as wiring for the new
module may be different than the existing module.
Unclip the existing module by inserting a screwdriver in the slot on the end of the retaining clip on each end of the
module, moving the clip outwards slightly to the unlocked position.
Remove the module up and off from the base by pulling upwards from the base.
Using a 3/16” socket or other suitable wrench, loosen each of the mounting posts slightly.
Referring to the chart below, find the proper key for the module to be inserted, and then move the key wheels to the
proper orientation.
Retighten the mounting posts securely.
Mount the new module making sure that the top of the module points towards the top of the base. The module wiring
socket is keyed as well, so inadvertent upside down mounting should not be possible.
Press in on the retaining clips on each end of the module to lock the module in place.
The module assembly is now ready for wiring as per the screw terminal charts found in Section 5 in this manual.
