Etherlogic LC
Introduction
An EtherLogic LC is a programmable controller, and much more.
An EtherLogic LC combines the programmability of a Programmable Logic Controller
(PLC), the communications capabilities of an advanced Remote Terminal Unit (RTU),
the alarm notification capabilities of an alarm dialer, and the data storage and
retrieval capabilities of a Data Logger. By integrating the capabilities of four separate
instruments, EtherLogic LCs reduce configuration and programming time, cost, and
integration headaches while requiring less panel space and power than separate
components.
Networking
EtherLogic LCs have a built-in Ethernet Port and support the common Ethernet and
Internet protocols. These protocols are used for file transfers, e-mail, web serving and
terminal access as well as standard industrial communications protocol called
Modbus TCP/IP. The built-in Ethernet capability is compatible with the latest
generation of Wireless Ethernet modems including 802.11 type devices and GSM,
GPRS and CDMA cellular systems.
EtherLogic LCs have an RS-485 compatible serial communications port for low-cost 2wire networking. RS-485 is used for I/O expansion as well as to interface to a variety
of intelligent industrial devices including loop controllers, variable speed drives and
other PLCs and RTUs.
Serial Communications
In addition to the RS-485 port, EtherLogic LCs have two RS-232 serial ports (one
shared with the RS-485 port) plus an internal port for a 56K baud telephone modem,
a GSM or CDMA cellular modem, or a 900MHz or 2.4GHz spread spectrum radio.
When outfitted with the telephone modem, an EtherLogic LC Controller supports
alarm dial-out and remote dial-in with voice alarm annunciation and touchtone/voice
access to internal register setpoints, process variables and I/O control.setpoints,
process variables and I/O control.
ScadaWorks IEC 61131-3 Programmable Logic
EtherLogic LC controller are configured and programmed with a Windows software
package called “ScadaWorks”. ScadaWorks combines the ISaGRAF IEC 61131-3
programming software from ICS/Triplex with ICLs ScadaBuilder software for
communications, networking, alarm annunciation and data logging in a single
integrated package. IEC 61131-3 is the international open systems standard for
industrial control programming, incorporating 6 different languages including ladder
logic. Every EtherLogic LC controller ships fully configured with an ISaGRAF IEC
61131-3 runtime license.

Etherlogic LC
Closely integrated with the ISaGRAF IEC 61131-3 software is ScadaBuilder, ICLs
Windows based software which configures all of the non-logic operating features of the
EtherLogic LC Controller. ScadaBuilder makes it easy to set-up Ethernet, Internet and
serial networking and communications with multiple protocols on individual ports,
configuring alarm handling and annunciation including voice, and setting up multiple
simultaneous data and alarm logs.
By combining IEC 61131-3 control with communications, alarming and data logging,
common resources such as tag names are shared, significantly reducing the time
required to build a SCADA system.
Internal I/O & I/O Processor
EtherLogic LC has a rich compliment of built-in analog and discrete I/O. This
includes:
♦
♦
♦
♦
4 Universal Inputs (5Vdc, 20mA, thermistor, ohms, contact closure)
2 20mA Analog Outputs
10 Discrete Inputs (including two very high-speed pulse inputs)
4 10A Relay Outputs
A dedicated I/O microprocessor relieves the main CPU of performing real-time I/O
tasks for improved performance and signal processing.
Internal Spread Spectrum Radio Options
The EtherLogic LC Controller is available with a 900MHz or 2.4GHz Freewave Spread
Spectrum radio. Three brands of 900MHz radios are available, offering a choice of
price and performance.
Internal Cellular Modem Option
The cellular telephone network provides a convenient means of connecting an
EtherLogic LC controller to the internet in remote locations. EtherLogic LC controller
are available with both GSM/GPRS and CDMA modems for compatibility with all
major cellular carriers.
Internal 56K baud Telephone Modem Option
The EtherLogic LC Controller is available with an internal high-speed telephone
modem. With this option, the EtherLogic LC Controller can dial out to annunciate
alarms, initiate numeric or alphanumeric pages, automatically upload data log files to
a server, and send e-mails. Likewise, the controller can be dialed into to access
register data and process variables, as well as download data logs and upload program
updates.

Etherlogic LC
EtherLogic LC Controller Architecture
The EtherLogic LC Controller has dual CPUs:
•
an 8-bit Reduced Instruction Set CPU (RISC) for analog and discrete I/O
•
a powerful 32-bit 386EX processor for communications and logic processing
The two processors communicate with each other using an internal communications
link.
I/O Processor
The I/O processor is pre-programmed to continually scan the four universal input
points, and based upon settings in configuration and calibration registers, interprets
the analog values as voltage (0/1 to 5Vdc), current (0/4 to 20mA), temperature (10K
thermistors), resistance (up to 65,000 ohms), or contact closures. Likewise, the ten
discrete inputs are scanned and their states stored. The universal inputs and discrete
inputs are totalized by the I/O processor, two of which can be software configured for
very high speed counting, such as for totalizing flow from a turbine flow meter.
The I/O processor also periodically refreshes the 4 discrete outputs and 2 analog
outputs from registers in the controller.
The Main CPU reads and writes the I/O processor registers over an internal
communications link. The I/O information that the Main CPU reads is filtered and
calibrated (using factory stored calibration values in nonvolatile memory) so that the
Main CPU needs to perform little or no additional processing except for optionally
scaling analog values to “engineering units”.
A watchdog timer in the I/O CPU continually monitors the communications activity
between the I/O CPU and the Main CPU. If the Main CPU stops “talking” to the I/O
CPU for a preset time period, all of the discrete and analog outputs are automatically
turned OFF for “fail-safe” operation. This feature can be disabled if needed.
Main CPU
The Main CPU supports three serial ports; 1 external RS-232 port, 1 external RS232/RS-485 port and an internal modem/radio port. RS-232 connections are
standard for most serial communications devices, but are limited to short (<100 ft.)
cable runs. RS-485 is less common, but supports networking of up to 256 parallel
devices over a distance of up to 4,000 ft.
The EtherLogic LC Controller has a built-in 10BASE-T 10Mb/s twisted pair Ethernet
port. The Ethernet Port provides high speed communications and is recommended for
linking controllers with each other as well as with other system components such as
PCs or the Internet.

Etherlogic LC
EtherLogic LC controllers are like desktop PC computers in many ways:
•
they use an Intel x86 computer chip.
•
they store programs in nonvolatile “disk” memory (solid state Flash memory in
EtherLogic LC Controllers).
•
they run programs in RAM memory loaded from the “disk”.
•
they have a battery-backed real time clock that allows programs to condition
their operation based on the actual time and date, and support logging of data
and alarm conditions with “time stamps”.
•
they can run multiple programs or pieces of programs (“threads”)
simultaneously so that communications, logic and I/O control operate
concurrently.
•
they communicate easily with other computers over networks and a variety of
physical mediums including twisted pair wiring, radios and telephone lines.
EtherLogic LC Controllers differ from desktop PCs in that:
•
they have no moving parts including their internal “disk,” making them
immune to vibration that would harm a “normal” PC.
•
they use components specially selected to operate reliably over a very wide
temperature range; -40ºC to +75ºC (-40ºF to 167ºF).
•
they don’t require a display, keyboard or mouse, but instead are designed for
both stand-alone operation as well as remote control operation over a network.
•
they have specially designed software to simplify and speed the development of
industrial control applications, alarming and data logging applications.
•
they come with a 3-year warranty.

Etherlogic LC
Status LED Indicators
EtherLogic LC Controllers have two green
LED status indicators and a reset switch
located near the lower left hand corner of the
controller.
POWER LED
When illuminated, the Power LED indicates
that power is applied to the controller. The lit
state of the indicator should not be construed
to indicate that the controller power is within
the specified operating range, but only that
AC/DC power is present.
CPU STATUS LED
The Status LED indicator is controlled by the Main Logic/Communications processor.
Under normal operation the flash intermittently during controller start-up, the at a
periodic rate while an ISaGRAF program is executing (“heartbeat indicator”). The LED
state can also be controller by a user program for application specific status indication
while a program is running.
Reset Pushbutton
Pressing the “Reset” pushbutton is equivalent to powering the controller OFF and then
ON. This will cause the controller to re-initialize and restart its operating program.
Network Address/Option Switches
EtherLogic LC Controllers have a bank of 8 “DIP” switches at the bottom right-hand
side of the controller. The switches can be used to set a network address in the field
without requiring a laptop computer. Depending on how they are configured, the
switches can represent a 1 in 256 address directly, such as for a Modbus Slave, or
they can represent the lower “octet” of a TCP/IP Ethernet address. If the switches are
not used for addressing, they may be used to select runtime options in a users
program.
Additional information on using these switches is contained in the
ScadaWorks/ScadaBuilder manual and Help files.

Mechanical Installation
EtherLogic controllers are designed to be installed in a protective enclosure with the
appropriate NEMA rating for the environment that the controller will be used. Typical
NEMA ratings are as follows:
North America:
Indoor applications only: NEMA 1 Indoor or Outdoor applications: NEMA 4, 4X or 12
rated enclosures.
European Union:
Must be installed inside IP54 or IP56 rated enclosures.

* Different RS-232 ports support different signal configurations. Some signals may not be available on some
ports and therefore do not need transient protection. Refer to the RS-232 pin out table later in this document
for details.
The enclosure material must be a minimum of 1.14mm (0.045”) thick. Typically, the
controller is mounted vertically in such an enclosure on a steel backplate. If an
alternative mounting scheme is used, it is recommended that the controller be
mounted on a noncombustible surface.
External surge suppression must be installed to limit all operating voltages to within
140% of signal voltage. This includes all RS-232 signals, Digital Input, and Pulse
Input terminals.
CAUTION: If the controller is mounted on or above a combustible surface (such
as a wood backboard), a plate of at least 1.43mm (0.056”) galvanized or 1.6mm
(0.063”) uncoated steel extending at least 150mm (5.9”) beyond the controller
on all sides must be installed.

Etherlogic LC
EtherLogic LC Analog & Discrete I/O
The EtherLogic LC Controller includes a full compliment of analog and discrete I/O:
♦
♦
♦
♦
4 Universal (Analog/Sensor/Discrete) Inputs
2 Analog Outputs
10 Discrete Inputs (2 include very high-speed counting support)
4 Discrete (relay) Outputs
Universal Inputs support “normal” 4 to 20mA and 0 to 5V process signal levels, as well
as resistance measurement and direct readout of temperature from 10K ohm
thermistors. The Universal Inputs can also accept contact closure and logic-level
discrete input signals.
Analog Outputs provide 20mA current loop control signals, or with a single resistor, 0
to 5 or 0 to 10V voltage control signals.
Discrete Inputs are optically isolated input points for sensing switch and contact
closures from on/off sensors. EtherLogic LC controllers are ordered as “12/24V” or
“120/240V” models depending on the signal levels of the Discrete Inputs. Two of the
discrete inputs are isolated from the rest and have programmable filtering, which
when minimized, allows these inputs to count pulses at rates beyond 5KHz.
Discrete Outputs provide contact closure signals to operate on/off type control devices.
The discrete outputs of EtherLogic LC controllers are heavy duty relays with contacts
rated to switch up to 10 amps (125Vac).
I/O Expansion: Additional I/O capacity is supported with a family of expansion
modules that connect to the controller via a high-speed 2-wire serial interface. This
provides the additional benefit of a distributed I/O system. Wiring cost is reduced by
enabling the I/O modules to be placed up to 5,000 feet away from the controller and
close to the sensors and control devices, thereby minimizing the distances for field
wiring runs.
Universal Inputs
The Universal Inputs accept both analog and discrete inputs signals from sensors that
monitor levels, flows, temperatures, pressure, etc. as well as discrete input devices
such as switches and relays contacts. Analog measurements are made with a rugged
10-bit Analog-to-Digital (A/D) converter.
The EtherLogic LC Controller has 4 universal inputs.
22
Copyright © 2007 Industrial Control Links, Inc. All Rights Reserved
Etherlogic LC
Signal Types and Levels
The universal inputs may be individually configured to accept standard 5V or 20mA
process control signals, resistive sensors such as thermistors and potentiometers, and
contact closures. With a pair of external resistors, the inputs can be configured for
higher voltages such as 0 to 10V or 0 to 30V dc.
The input mode, sensor type and scaling are software configurable using ICLs
ScadaBuilder software in an I/O configuration screen. An example EtherLogic I/O
configuration is pictured below.
Each channel has a mode setting that may be set to “Raw”, current (mA), voltage (5V),
resistance (ohms), or a choice of two type of thermistors reading out in degrees F or C.
Note in the far right column, the amount of filtering can also be individually
configured for each input. On start-up, the main CPU downloads the configuration
information to the I/O processor to set the mode and filtering parameters that the I/O
processor will use for processing the analog input data from each channel.
RAW Mode
Raw mode bypasses all scaling and calibration in the I/O processor, providing “raw”
10-bit readings from the A/D converter. A full scale reading of 1023 represents an
input of approximately 5Vdc. If the current configuration switches are enabled, the
input current can be calculated as the voltage drop read across a precision 121 ohm
resistor, or just over 20mA for a full scale readings of 1023. The calculation is:
A/D Reading = (1023 * mA * 243) / 5000
If the current sources are enabled (for resistance measurements), the RAW readings
are the ratiometric values read across the input resistance in series (bottom portion of
a voltage divider) with a precision 10,000 ohm 0.1% low-drift resistor connected to the
A/D reference. The calculation is:
Copyright © 2007 Industrial Control Links, Inc. All Rights Reserved
23
Etherlogic LC
A/D Reading = 1023 * R / ( R + 10,000)
where R is the resistance being measured.
5Vdc Mode
When configured for voltage measurements, the EtherLogic LC Controller measures
signals from 0 to 5 volts. The I/O processor scales and performs calibration correction
on the readings, so that a full scale reading of 5Vdc is presented to the main CPU as a
value of 5000 (1,000 counts per volt). This provides readings that without further
scaling, read out directly in 1mV increments (imagine a decimal point 3 places from
the right to interpret the readings in volts). The Scaling section of ScadaBuilder can be
used to change this scaling to more meaningful engineering units.
20mA Mode
When configured for milliampere measurements, the EtherLogic LC Controller
measures signals from 0 to just over 40mA (200% over-range for “standard” 20mA
signals). The I/O processor scales and performs calibration correction on the readings,
so that a full scale reading of 40mA is presented to the main CPU as a value of 40000
(1,000 counts per milliampere). The milliampere mode is typically used to measure the
output of 4 to 20mA sensors. The readings from these sensors will come into the Main
CPU as 4000 for 4mA and 20,000 for 20mA.
Current is measured by reading the voltage drop across a precision 243 ohm resistor
through which the current is flowing. Besides setting the input mode in the
ScadaBuilder software, current loops require that the current sense resistors be
enabled by setting DIP switches (labeled AI Mode 20mA/Std) in the upper left-hand
corner of the controller near the Universal Input terminal blocks connections. There is
a separate switch for each input.
Resistance Modes
EtherLogic LC controllers can measure resistance from 0 to 65,535 ohms. The
readings can be scaled to engineering units, such as degrees of rotation for a
potentiometer or temperature for a resistance type temperature sensor that is not
automatically handled by the I/O processor. The ScadaWorks software provides
functions for linearization of nonlinear sensors.
Resistance is measured by sourcing current through a precision 10,000 ohm reference
resistor that is in series with the sensor. The current through the sensor is limited to
less than 0.5mA to minimize the effects of self-heating. The I/O processor measures
the voltage drop at the junction of the reference resistor and the sensor and compares
it to the reference voltage. The I/O processor is then able to ratiometrically calculate
the sensor resistance.
If the I/O processor is configured for thermistor temperature sensors, the calculated
resistance is automatically converted to a linearized temperature reading in degrees F
or degrees C. The I/O processor is programmed to directly support two types of
24
Copyright © 2007 Industrial Control Links, Inc. All Rights Reserved
Etherlogic LC
industry standard 10,000 ohm thermistors. Other types of thermistors can be
supported by taking the resistance reading in ohms and having the Main CPU
calculate the corresponding temperature using an ISaGRAF “CHARCTRZ” block for
linearization and conversion.
Contact Closures
In addition to resistance measurement, the internal current sources are also used to
support contact closure input signals so that no external power source is required.
To use a Universal Input to sense a contact closure, the input MUST be configured for resistance
measurement.
Thermistors
Thermistors are temperature sensors that are popular for use in HVAC, building
monitoring and automotive applications. The resistance of a thermistor varies nonlinearly with temperature, so the I/O processor automatically corrects for the nonlinearity and provides a calibrated reading in degrees C or F to the controller.
The EtherLogic LC Controller supports two common types of thermistors; 10K ohm,
Type II and III (resistance is 10,000 ohms at 25ºC/77ºF). The only difference between
them is the “shape” of their temperature to resistance curves. The supported
temperature ranges and corresponding readings from the I/O processor are:
Sensor Mode
Type II - Deg C
Type II - Deg F
Type III - Deg C
Type III - Deg F
Temperature
-40.1oC to 203.4oC

thermistors directly supported by the EtherLogic LC controller.

Input Protection
The Universal Inputs are overload, surge, and reverse polarity protected by a
combination of self-resetting polymer fuses and “Transorb” transient limiters. Input
levels greater than 6Vdc or 24mA, or negative signal levels will cause the transient
protection circuitry to start limiting the input signal. Greater overloads will cause the
polymer fuses to begin to increase in resistance protecting the internal analog
circuitry. During a full overload condition, the inputs will conduct some current, but
that current is held at a safe level. When the fault is cleared, the input is restored
back to normal operation automatically.
Calibration
The calibration of the universal inputs is software controlled. Calibration tables for the
inputs are stored in nonvolatile EEROM and calibration is performed by software
techniques without making mechanical adjustments.
26

Etherlogic LC
Field Wiring
The universal input connections come into the Controller on 8 positions of a 16
position removable terminal block. There are 4 sensor input connections and 4
common connections, one per input channel. The common connections are electrically
tied together within the Controller.
For 20mA or 5 volt sensors, the universal inputs are passive, requiring an active
signal source. 20mA current loop devices must either have their own internal loop
power supplies, or an external supply must be used (such as the Auxiliary DC Output
built into the EtherLogic LC). Voltage type sensors are typically self-powered anyway.
It is best if self-powered devices are isolated to avoid ground loops.
Current for resistance type sensors is automatically sourced from the controller when
the controller program is configured for resistance or thermistor measurements on an
input. In these cases, no external source is required; the sensor is simply connected
across the input connections.

NOTE: The terminal block screws must be tightened to 7 lb-in.
Please refer to the preceding installation section for additional electrical wiring requirements.
Discrete Inputs
Discrete inputs are used to monitor the state of switches, relays contacts, motor
starter auxiliary contacts and any other on/off type sensor signal. In the EtherLogic
LC, the discrete inputs are optically isolated to avoid ground loop effects and prevent
damage from transients and power surges on the input lines.
The EtherLogic LC controller has 10 discrete inputs. These inputs are labeled DI5
though DI14 (the first 4 “discrete inputs” are actually part of the Universal Inputs that
accept only contact closures and low-voltage input signals).
Copyright © 2007 Industrial Control Links, Inc. All Rights Reserved
27
Etherlogic LC
Signal Types and Levels
The discrete inputs have a unique input design that accepts both AC and DC signals.
The inputs are not sensitive to signal polarity, supporting DC sensors with either
“sinking” or “sourcing” output configurations as well as switch contacts with AC or DC
signals.
The discrete input circuitry of the EtherLogic LC controller is purposely designed to
respond to DC signals (that do not cross through 0 volts) faster than AC signals. This
provides better noise rejection in systems with 50Hz or 60Hz control power, but allows
for a little faster response times in machine control applications that typically use DC
photoeyes and proximity switches.
The standard EtherLogic LC discrete inputs are designed to operate in 12 and 24 volt
control systems or 120 and 240 volt control systems depending on the model number
ordered. The guaranteed ON and OFF thresholds and maximum input ratings are:
Model Type
12 / 24V
120V
OFF Threshold
6 Vdc/Vac
50 Vdc/Vac
ON Threshold
9 Vdc/Vac
75 Vdc/Vac
Maximum Input
50 Vdc/Vac
250 Vdc/Vac
The EtherLogic LC discrete inputs have hysteresis in order to improve their noise
rejection. The hysteresis ensures that the voltage at which an input turns ON is higher
that the voltage at which the input will turn OFF. Once the input signal reaches the
ON threshold, it must drop down below the OFF threshold for the input to turn OFF.
This feature combined with normal component tolerances defines the difference
between the “guaranteed” OFF and “Guaranteed” ON thresholds in the table above.
Pulse Totalization
The I/O processor in the EtherLogic LC performs pulse totalization on all Discrete
Inputs (including the Universal Inputs), providing reliable fast pulse counting that is
not sensitive to program scan time.
To use one of the I/O processors pulse totalizers, simply map the tag name of an
integer variable to the appropriate channels counter as shown below.
28
Copyright © 2007 Industrial Control Links, Inc. All Rights Reserved
Etherlogic LC
Note that DI13 and DI14 have controls in the column labeled “DI_Filter”. When these
filter bits are set to “OFF” as shown, these discrete inputs can count high-speed
pulses in excess of 5KHz. With the filtering turned ON, the input counting rate is
limited to 40Hz (DC pulse) or 10Hz (switched AC). On all of the other “standard”
discrete inputs (DI5 through DI12), the filtering is fixed ON, so these inputs are
limited to 40Hz (DC) and 10Hz (AC) counting rates. The Universal Inputs (DI1 through
DI4) may also be used for pulse counting at rates of up to 500Hz.
The pulse totalizers are 32-bit counters, meaning that the totalizers count up to
4,294,836,225 ON transitions before they “roll over” to zero again. The counters can
be reset to zero at any time under program control by writing a 0 to the register. Like
any other registers, totalizer registers can be declared as “retentive” (nonvolatile) so
that the accumulated values will be remembered through a power failure. The built-in
counting features can be used for very accurate flow and wattage totalization,
including monitoring flow rates using high-speed turbine flow meters.
Field Wiring
Discrete input signals come into the Controller on 12 positions of a 20-position
removable terminal block. There are 10 sensor input connections arranged in groups
of 8 and 2 inputs with separate commons for each group.
The discrete inputs are passive and require an active voltage to be switched between
input signal connections and their common connections to complete the input
circuits. The inputs are isolated, so that the power source for the inputs can safely be
the Controller power supply or the controllers Auxiliary DC output, without causing a
ground loop. The inputs are not sensitive to polarity, so the power lead connected to
the field sensors can be either the negative or the positive side of the power source.
The input current at 12Vdc is approximately 1mA, sufficient for contact “wetting”, but
low enough for practical use in solar and battery-backed applications.

Discrete Inputs – Field Wiring Example (wiring for 12/24V model shown)
Remember that the two “C” common connections are isolated from each other. If all of
the Discrete Inputs are to share a common, the two “C” terminals must be jumpered
together.
NOTE: The terminal block screws must be tightened to 7 lb-in.
Please refer to the preceding installation section for additional electrical wiring requirements.
Discrete Outputs
Discrete outputs are used to control motor starters, lights, annunciators and any
other type of on/off control device. The discrete outputs are individually isolated 10
amp “dry” relay contacts (refer to load ratings below). The contacts have built-in
snubbers to reduce arcing and radiated electrical interference. The outputs can switch
both low-voltage and 120V/240V loads.
EtherLogic LC controllers have 4 discrete relay outputs.
Field Wiring
The discrete outputs are passive “dry” contacts and require an active supply voltage
on one side of the load, while the relay output from the controller switches the other
side of the load to the opposite supply leg. The outputs are isolated so that they can be
inserted in the “middle” of external control circuits and can switch external signals
without causing ground loops. The relays may be used to switch AC or DC signals
and power. The maximum rating of the load that may be switched and the relay
contact life depends on the type of load and the applied voltages as follows:
General Use (Resistive Loads)
Inductive Loads

10Amps @ 125Vac, 5 Amps @ 250Vac or 30Vdc - 100,000 cycles

No fusing or overload protection for the discrete outputs is provided within the
controller. External protection should be included in the output circuits to protect
both the controller relay contacts and the loads that they drive. Typically, large loads
are fused individually, while smaller loads share a fused leg.
The relay output contacts of
EtherLogic LC controllers have
built-in snubber protection. These
snubbers, wired across the relay
contacts, reduce arcing that
degrades the contacts and can
cause premature relay failure
when controlling inductive loads
such as relays and motor starters.
Even with snubber protection,
some people choose to incorporate
the added protection of transient
suppression diodes across DC
coils, and MOVs or other clamping
devices across AC coils.
When using diodes (DC circuits),
be sure to observe the polarity of
your connections. A reversed diode
will actually cause a short circuit!
Metal Oxide Varistors (MOVs) may
be used for AC and DC circuits,
and are not polarity sensitive.

Analog Outputs
Analog outputs are used to control variable speed drives, valves, positioners and
dampers as well as chart recorders and digital displays. The EtherLogic LC Controller
has two 10-bit analog outputs.
Signal Types and Levels
The two analog outputs produce 0 to 20mA control signals. With the addition of a
single external resistor (per channel), the outputs can be converted to voltage outputs
(i.e 0 to 5Vdc or 0 to 10Vdc).
The resistor value can be calculated as: Rsense = Vout / 0.02
The resistor values required for
common voltage ranges are:
Range

0 to 5Vdc

The EtherLogic LC analog outputs source current from the Controller power supply.
The common of the analog outputs are connected to the controllers power supply
common. Control devices connected to these two outputs should be isolated to avoid
unforeseen ground loops.
Output Scaling
The EtherLogic LC Analog Outputs are scaled to provide a 0 to 20mA output signal
with output values of 0 to 2,000 (1 count = 1uA). The outputs have an additional 5%
or so of headroom, so it’s possible to use values greater than 2,000 to get output levels
slightly higher than 20mA. Note that since the outputs have an actual resolution of
10-bits (a range of 0 to 2,000 would actually need about 11 bits), it will require an
increase or decrease of a couple of counts in the analog output value to cause a
change in the actual current output. The 0 to 2,000 scaling is simply done for the
convenience of system setup. If desired, the analog outputs can be rescaled by
changing or adding a scaling record in the I/O section of Scadabuilder.
The common 4 mA offset required by 4 to 20mA control devices and indicators can
also be set up in the scaling portion of the ScadaBuilder software.
32

Etherlogic LC
In the sample ScadaBuilder scaling record on
the right, a value of 0 to 1000 will be
translated to a 4 to 20mA signal
(corresponding values of 400 to 2000 sent to
the I/O processor).
Calibration
The Analog Output calibration is software
controlled. Calibration tables for the analog
outputs are stored in nonvolatile EEROM and
calibration is performed by software techniques
without mechanical adjustments (pots).

Etherlogic LC
Ethernet
EtherLogic LC Controllers come with an Ethernet port, providing higher speeds and
more connectivity features than serial ports. The Ethernet Port can be used as a highspeed point-to-point connection to a single PC, connected in a wired or wireless
network of Controllers and PCs, or connected to the Internet via a DSL, cellular or
cable modem.
Ethernet connectors look very similar to standard
telephone connectors. Be sure that a “normal” telephone
line is NEVER plugged into the Ethernet connector.
Although it most likely will not damage the EtherLogic
Advanta controller, it will probably disrupt normal
telephone operation.
Ethernet has several different standards for the type of media or wiring that is used to
interconnect devices. EtherLogic LC Controllers support the more common 10BASE-T
unshielded twisted-pair standard.
10BASE-T differs from other Ethernet topologies. Instead of tapping off one long cable,
each Ethernet device has a point-to-point connection with either a hub or a switch. In
some systems, a switch will provide improved performance over a hub, but in most
systems using EtherLogic LC controllers, there will be very little difference. One
exception: a single PC can be connected to a single Controller using a “crossover”
cable without using a hub. Use pre-made (and tested) “CAT5” patch cables to connect
EtherLogic LC Controllers to hubs or switches.
One big advantage of using 10BASE-T is that each Ethernet device is isolated from the
other devices on the network. When common wiring errors occur (such as shorts) , the
problem will only affect a single device on the network without bringing down the
entire network.
The 10BASE-T specification limits the wiring distance between EtherLogic LC
Controllers and a hub or switch to 328ft. (100meters). Hubs and switches act as
buffers, extending the reach of networks. There is a limit of up to 4 hubs that may be
used in one chain.
Typically, an Ethernet network consists of a main high-speed “backbone” with taps to
switches or hubs that then feed down to devices like EtherLogic LC Controllers.
Because of the 100 meter/link and 4 hub limits, EtherLogic LC Controllers can be up
to 1,300 ft. away from the “backbone” without resorting to other buffering techniques.

Serial Communications
The most common serial communications standard in SCADA and industrial control
systems are RS-232 for short point-to-point connections, and RS-485 for longer pointto-point and networked communications. The EtherLogic LC Controller has 1 RS-232
serial port and one combination RS-232/RS-485 serial port.
RS-232 Serial Communications Interfaces
Both external serial communications ports are RS-232 compatible. Both ports are
designed for high-speed communications to 115K baud, although the second port has
additional buffering and should be used for extremely high-speed communications if
needed. The first port (COM1), typically used as a console and diagnostic port, is the
simplest and has no modem control lines associated with it. The second port has
nearly all modem control lines, ideal for external radio and telephone modems. Both
serial ports use 9-pin male “D” connectors in exactly the same configuration and
pinout as an IBM/PC compatible computer so you can you low-cost easy-to-find
cables.
The RS-232 connector pin assignments and supported signals on each RS-232 port

Power
EtherLogic LC Controllers operate from either AC or DC power, from 10 to 28Vac or 10
to 36Vdc. The power consumption of the Controllers is very low; less than 2 watts
typical, with peaks of up to 6 watts, depending on installed options. Because of their
low power consumption and wide input power range, they are ideal for solar or battery
backed applications.
A 12Vac or 24Vac control power transformer or the ScadaFlex DC Power Supply are
recommended for non battery backed applications, while the ScadaFlex UPS is
recommended for battery-backed systems. The wide operating temperature rating of
the ScadaFlex power supplies compliments the EtherLogic LC Controller, while the
simple control transformer solution provides the lowest cost alternative for less
demanding applications. The ScadaFlex UPS is especially worth considering as
economical insurance against unreliable “brownout” prone AC power sources.
If an AC power source is used, an auxiliary DC power output is available to power
analog loops and/or a ScadaFlex Viewpoint operator interface. The output voltage
depends on the input power, although it is limited so as to not exceed 30Vdc. The
output is short-circuit protected and rated to supply up to 0.25A.
Power Wiring
The power wiring uses 4 terminals of a 16-position removable terminal block shared
with the analog inputs and outputs as shown below:

Etherlogic LC
Maintenance
EtherLogic LC Controllers are designed for long-term maintenance-free operation. The
only maintenance items typically required by the Controller are occasional
replacement of a clock battery, setting the time and date, analog calibration and
possible software and firmware updates.
Clock/Calendar/NV RAM Battery
The internal Real Time Clock, Calendar and nonvolatile register memory have a small
lithium “coin” style battery that keeps these circuits running when there is no power
to the controller. The battery is retained in a holder that is accessible from the bottom
of the controller.
Depending on the ambient temperature and how often and long the controller is left
powered off, the battery will need to be replaced every two to five years. A boolean bit
may be assigned to an internal battery monitor circuit that monitors the battery
condition. If this feature is taken advantage of, a controller program can annunciate
an alarm to provide an early warning that the battery will need replacement.
The replacement battery is a Renata/Rayovac CR2032. When you replace the battery,
be sure to pay attention to the batteries polarity. A large “+” sign should be readily
visible on the top of the battery.
Clock/Calendar/NVRam
Battery
Time & Date
Using a PC running a terminal emulation program such as HyperTerminal (supplied
with Windows) or ScadaBuilder, the Time and Date can be viewed and set from the
“C>” prompt when the PC is connected to COM1 of the Controller. To get to a “C>”
prompt, cycle the Controllers power or press the “Reset” button, then press the Escape
key on your computers keyboard several times while the Controller is just starting to

“boot”. Type “TIME” followed by a carriage Return to View the current time setting. Do
the same with the DATE. To change the Time or Date, enter a new value when
prompted.
There are also functions and function blocks built into ScadaBuilder for setting the
time from within a program, or automatically updating the time from a Global
Positioning System (GPS) receiver.
Calibration
The calibration of analog inputs and outputs should be checked typically once a year.
The calibration values for the EtherLogic LC Controller are retained in nonvolatile
EEROM memory, and may be viewed and changed using a ScadaBuilder application
available from Industrial Control Links. Please contact technical support for a copy,
along with the recommended field calibration procedure. A backup copy of all
calibration values, as determined by an automated test system in the factory, is
always retained separately in another area of nonvolatile memory, “just in case”. The
same ScadaBuilder application can restore the factory calibration values if needed.
Software and Firmware Updates
Controller software is easily and quickly updated using ICLs ScadaBuilder software
with its built-in Kernel and Configuration update functions. In addition, the I/O
processors firmware can be “drag and dropped” into the terminal window which
automatically transfers it to the flash “disk” on the Controller. The new firmware can
them be installed using a Bootloader program shipped with the Controller or available
from the ICL web site (Note: the “drag and drop” mechanism can be used with any files
to be sent to the Controller). Please refer to the ScadaBuilder documentation for more
information.
Internal Telephone Modem Option
EtherLogic LC Controllers can be ordered with an internal 56K baud dial-up telephone
modem. With the internal telephone modem option, the Controller can dial out to
annunciate an alarm with synthesized voice (including “real-time” process variables),
send a message to a numeric or alphanumeric pager, send a text message to a cell
phone, or send an e-mail (with file attachments such as data logs).
The EtherLogic LC Controller can also be configured to accept incoming calls for
remote PC or touchtone voice-prompted access to process variables, and to make
password protected register and I/O changes, as well as for remote program
debugging and updates.
The internal telephone modem is functionally similar to the high-speed modems used
in PC computers, except that the LC internal modem has the following additional
features:
•

•
runs off of internal DC power from the Controller, making it easy to provide
long-lasting uninterruptable battery backed operation.
The modem telephone connector and status lights are built into the upper side of the
Controller. The connector accepts a standard 6-pin modular telephone plug, of which
only the center two pins are used for the telephone line connection (standard
telephone wiring configuration).
Internal Spread Spectrum Radio Option
(Freewave)
EtherLogic LC controllers are available with internal Spread Spectrum Radios,
requiring no license and supporting data rates of up to 115K baud.
The spread spectrum radios used in LC controllers may be ordered for operation in
either one of two bands designated by the Federal Communications Commission
(FCC); 900 MHz (902 to 928MHz) and 2.4GHz ((2.400 to 2.4835MHz). Unlike
conventional radio systems that transmit and receive on fixed frequencies, spread
spectrum radios “hop” periodically from one frequency to another in a pseudo random
pattern. The hopping pattern is user settable, and all radios that are configured to talk
to each other follow this pattern, changing frequencies up to 100 times per second.
The radios can utilize a total of 112 different frequencies.
Spread spectrum radios tend to be less affected by outside interference and are more
secure than conventional radios because they are constantly changing operating
frequency. If a spread spectrum radio encounters interference at a particular
frequency, it simply picks up where it left off after hopping to the next frequency a few
milliseconds later. The radios offer very high data reliability, utilizing a unique 32-bit
error detection and correction scheme to ensure that corrupted data is never passed
to the Controller. This protection is above and beyond the protocol level error
handling.
The embedded radio can deliver up to one watt of RF power, the maximum allowed by
law in these frequency bands. This is typically a lower power level than other types of
radios operating at fixed licensed frequencies, but these spread spectrum radios can
have a range of up to 60 miles in an open area. The radios have a built-in repeater
function, so that each radio can serve as a repeater to relay the messages of other
radios located farther out as well as communicating the data from the Controller.
There is no limit, other than transmission time, to the number of repeater hops used,
so spread spectrum radio networks can provide hundreds of miles of coverage.

The internal radios support real-time on-line diagnostics that enable a single LC
Controller to serve as a central point to examine the status of any other radio and

Radio Installation
The internal spread spectrum radio is
manufactured by Freewave Technologies
(www.freewave.com) and is functionally
similar to their stand-alone FGR series
radios without requiring any additional
panel space, cabling or integration effort.
Etherlogic
Freewave DGR and FGR series radios
may be used together with the
EtherLogic LC radio options.
The EtherLogic LC radio option uses a
female “SMA” type antenna connector.
The antenna connector and the radio
status lights are located on upper side of
Don’t forget the Lightning Arrestor
the Controller (see below) as well as on
the front of the controller.
Typically, a short, lightweight cable (such
as RG-223 or LMR-200) connects
between the radio antenna connector
and a lightning arrestor in the panel. A
lightning arrestor with dedicated ground
rod is required for any outdoor
installation. The lightning arrestor can also serve as a bulkhead connector to pass
through the cabinet wall and transition to heavier, lower-loss type exterior antenna
cables such as LMR-400 and LMR-600. These cables then connect to Yagi (directional)
or Omni (omnidirectional) antennas. LMR-600 cable has lower loss for longer runs.
LMR-400 is cheaper and more flexible, but less than 100ft. of cable can cut the signal
strength in half! Heliax has the lowest loss, but is stiff and hard to work with.

Once the radio system has been verified, all exterior connections should be taped and
weatherproofed for long-term reliability.
Radio Configuration
The internal spread spectrum radio is automatically connected to an extra serial port
(COM4) within the Controller. The port can be configured like any other serial port
including parameters such as baud rate, parity, etc. Like any other serial link, the
radios operating parameters must be set to match those of the attached serial port in
the EtherLogic LC Controller. While the radio serial port parameters are set using ICLs
ScadaBuilder software on a PC, the radio is configured using a PC computer
connected to the radio diagnostic serial port close to the antenna connector. Use a
“straight through” serial cable. Communicating with the radio requires a terminal
emulation program. This can be either the terminal emulator built into ScadaBuilder
software, or the HyperTerminal software that comes with Windows, or similar
alternative software. Set the terminal emulation configuration to:
19,200 baud, no parity, 8 data bits and NO flow control
The configuration menus in the radio are accessed by typing “Shift U” (be sure that
“Caps Lock” is OFF, then while holding down the Shift key, press the U key). You
should see the menu pictured below and the three internal radio status lights at the
bottom of the controller should be GREEN. Pressing the Escape key several times will
return the radio to normal operation.
Radio Configuration - MAIN MENU
When the radio has been placed into configuration mode, the radio status lights will
glow green and the Main Menu screen will be displayed:
From this menu, a series of sub-menus are accessed to examine or set operating
parameters. The radios are highly configurable, but for most applications, only menus
0 (Set Operation Mode), 1 (Set Baud Rate), 3 (Edit Radio Transmission
Characteristics), 4 (Radio Statistics) and 5 (Edit MultiPoint Parameters) are applicable
and discussed in the remainder of this section. A full operations manual for the radios
is available.

Radio Configuration - SET OPERATION MODE
The “Set Operation Mode” screen is selected by pressing “0” at the Main Menu. In this
screen, the radios basic operating mode is chosen. The screen is depicted below:
The current operating mode for the radio is always shown at the top of this screen just
under the title header.
Of the 9 available operating modes, only three of the modes are typically used with the
Advanta controllers. These three modes are the “Point to Multipoint” operating modes:
Point to Multipoint Master
In this mode, there must be one, and only one Master radio in a system. All of the
other radios in the network will operate as slaves to the Master. Designate one radio
as the Master using selection #2 in the menu.
Point to Multipoint Slave
After a single radio has been designated as the Master, the remaining radios in the
network must be set as “Slaves” using selection #3 in the menu.
Point to Multipoint Slave/Repeater
To reach outlying areas in the network, the Slave radios can act as repeaters. Slave
radios that will also act as repeaters are configured using selection #7 (Point to
MultiPoint Repeater) in the menu. Be sure to also enable Slave/Repeater operation in
Menu #5.
Return to the Main Menu
Once a radios mode has been set, press the ESC (escape key to get back to the Main
Menu (only press once, or else you will end up back at the “C>” prompt).

Radio Configuration - SET BAUD RATE
The “Set Baud Rate” screen is selected by pressing “1” at the Main Menu. In this
screen, the radios basic serial communication parameters are chosen. The screen is
depicted below:
The current communications speed (baud rate) setting for the radio is always shown
at the top of this screen, just under the title header. The baud rate can be set to any
one of ten standard speeds by simply typing a 0 through 9 corresponding to baud
rates of 1,200 baud to 230,400. Any of these speeds may be used with the EtherLogic
Advanta controller. The speed selected MUST match the port speed selected using the
ScadaBuilder configuration software for the controller.
Parity
The radio supports the standard “Odd, Even or None” parity selections. For most
applications including those using Modbus, 0 or “None” should be used.
Modbus RTU
This parameter should normally be set to “1” (enabled), forcing the radio to keep the
integrity of a single message as one packet instead of using multiple packets which
does not meet Modbus standard timing requirements.
RS-232/485, Turn Off Delay, Turn On Delay and Flow Control
These are not used in the Advanta controller and must be set to “0”.
Setup Port
Set this parameter to 3. This enables both radio ports for configuration.

Etherlogic LC
Radio Configuration - EDIT RADIO PARAMETERS
The “Edit Radio Transmission Characteristics” screen is selected by pressing “3” at the
Main Menu. The screen, with typical settings for an Advanta based SCADA system, is
depicted below:
The parameters in this menu are geared towards handling special circumstances and
should normally be left as shipped from the factory. One item though; “Remote LEDs”,
must be turned on in order to enable the status LEDs located between the COM1
connector and the address switches. Be sure this parameter is set to a 1.
Most of the other parameters in this screen are used to optimize the radios operation
in the event of problems in the field. They improve the operation of the radio in close
proximity with other radio networks, in high (radio) noise environments, or to optimize
the operation of the radio for certain mixes of data or types of protocols. In general,
the radios are plug-and-play and these parameters are best left at the factory settings
unless a technical support person recommends changing them.
Typically, your radio setup should match the screen pictured above.
Radio Configuration - SHOW RADIO STATISTICS
The “Show Radio Statistics” screen is selected by pressing “4” at the Main Menu. The
screen is depicted below:
46
Copyright © 2007 Industrial Control Links, Inc. All Rights Reserved
Etherlogic LC
The radio statistics screen shows an accumulated history of information regarding the
performance of the radio and the quality of the radio link. Unlike the “real-time”
updated information available at the Master, this information is a snapshot that can
only be viewed while not operating, but it does provide a local tool to analyze the
performance of a radio link.
Master-Slave Distance (m)
This value in meters is valid for distances over 1 Km (0.6 miles)
Radio Temperature
Should be 75 (°C) or less.
Average Noise and Signal Levels
These values are an average across all frequencies. Detailed information by frequency
is available by displaying the Frequency Table accessed from this screen (see lower
prompt line). Ideally, the noise level should be below “30” and the signal level should
be at least “15” more than the noise. Note that this is NOT in dB, but arbitrary units
to provide a relative signal strength and noise measurement.
Overall Rcv Rate (%)
This value provides an indication of the quality of the radio link and the impact on
data throughput. A good quality link will have an Overall Receive Rate of 75% or
better. The radio will not pass erroneous data, but a lower Overall Receive Rate
indicates that data throughput might be affected at higher data rates, such as
115,200 baud.
Radio Configuration - EDIT MULTIPOINT PARAMETERS
The “Editing MultiPoint Parameters” screen is selected by pressing “5” at the Main
Menu. The screen, with typical settings for the EtherLogic Advanta, is depicted below:

Etherlogic LC
Number of Repeaters
Repeaters extend the range of a radio network at the expense of speed. Any radio can
also serve as a repeater. Set this parameter to 1 if you are using ANY repeaters. All
radios in the network must have the same setting.
Master Packet Repeat
With a high quality link, set to 0 or 1 for maximum throughput. With a poor quality
link, a higher number will improve getting individual messages though at the expense
of speed and throughput. For Modbus networks, this value must be set to 3.
Network ID
This parameter helps avoid conflicts with other radio networks. All radios in the
network should be set to the same ID value. Other networks must use a different
value. Set this to any value below 4095, except the default (255).
Slave/Repeater
Set to 1 if this radio is a repeater as well as a node on the network. Be sure to set the
Modem Mode (Menu #2) to (7) Multipoint Repeater also.
Diagnostics
Set to 1 for this radio to provide diagnostic data back to the Master.
