1. Product Description
1.1 Position Sensor Background
Position sensors are typically used to provide an absolute position from a mechanical moving device to a
controller unit. The position information is either used to measure a position or to close the servo loop for
an automatic positioning system. The key characteristics of an absolute position sensor are:
• Range
• Accuracy
• Resolution
• Time response of the actual position
1.2 Fiber Optic Position Sensor
The MR430 series fiber optic position sensor system is an innovative all-optical design immune to any
electro-magnetic interference such as lightning, radiation, magnetic fields and other harsh environmental
conditions. The fiber optic aspect of the sensor also makes it perfectly suited for sensing position at high
voltage power lines, within high magnetic fields (MRI) or explosive atmospheres. This innovative product
measures absolute angular position from 0° to 360° with 13-bit resolution and distances up to 100 feet.
Figure 1. Micronor MR430 Fiber Optic Position Sensor System
The sensor utilizes Plastic Optical Fiber for sensing the exact position of the sensor disk. There are two
fibers, the Transmit fiber sends a short light pulse of light at a wavelength of 645nm to the sensor. A unique
code on the sensing disk impresses the code image to the receiving imaging fiber. The controller analyzes
the code impressed on the Receiving fiber and determines the exact position. Since the sensor is
electrically passive, it can be deployed in EMI/RFI intense environment without being disturbed by such
interference.
The position signal is measured and updated at a rate of 1.2 kHz. The controller provides a host of
interface capabilities, including: scalable analog voltage and current outputs, digital SSI (Serial
Synchronous Interface) output, USB, and a Modbus compatible serial interface.

3.2 Mounting the Controller Unit
The controller unit mounts on standard 35mm DIN rail, or it can be screw mounted to a wall or cabinet.
• For DIN rail mounting, insert clip to the unit and then clip onto DIN rail by bending the clip tabs
toward of the enclosure.
• When screw mounting, remove clip from enclosure and use screws to affix clip to the wall and
then clip enclosure onto the plastic clip. Both mounting schemes are shown below.
IMPORTANT:
• The optical power emitted by the Controller is classified both Eye-Safe (Class 1) and Inherently
Safe (Ex op is).
• By design, the optoelectronic Controller must be installed in a non-hazardous, Safe Area.
Figure 3. Mounting MR430 Controller on DIN Rail

The Sensor Controller requires
24V DC and consumes
approximately 60mA.
A number of interface options
exist:
Voltage and current outputs are
scalable using the ZapView®
software.
The 4-20mA current output is
isolated and requires an external
voltage source.
The Homing input requires a
18V to 24V logic or switch signal.
Figure 4. Connections to the MR430-1 Controller
The SSI interface usually connects to a PLC, servo drive unit or other position indicator. The SSI allows for
clock speeds of up to 250kHz and block read-out speeds up to 10kHz. Signals are available on connector
J3 which is shared with the Modbus interface signals.
The Modbus/RTU interface is available at connector J3. Controller units are slave devices and the device
address is programmable via this interface or the USB interface. Standard Baud rate is 57,600, 1 Stop Bit,
No Parity. The default Common Device Address is 235.
The USB interface is a serial FTDI Virtual Communications Port (VCP) serial emulator. It operates exactly
the same way and the protocol must be Modbus/RTU. Whenever the USB is connected and active, the
Modbus/Interface is disabled.

3.4 Optical Connection
The system uses two POF fibers:
a.) Transmit fiber is a standard 1mm POF fiber. On controller
this fiber connects straight into the blue LED transmitter
receptacle. Push fiber all the way to the stop and then
gently lock the blue collar nut.
b.) Receive fiber is a plastic optical imaging fiber (POIF). On
the controller the end is terminated and has a high quality
polished finish. (do not scratch). The fiber is terminated
into an SMA connector with a key. Locate the key and
insert connector all the way and hand tighten the SMA
hex nut.
On the sensor end, the two POF fibers terminate into a special
purpose connector. This connector end is polished and must be
protected from scratches and contamination. This connector is a
service connector only, and it should be disconnected only when
mounting or servicing the sensor.
When sensor is disconnected cover sensor opening with a tape.
3.5 Blink Status and Error Codes
Status information is provided by a blinking PWR LED.
See Section 5 for more details regarding status and error codes.

MICRONOR INC.
MR430 Fiber Optic Position Sensor System
Page 13 of 50
When the MR430 controller indicates an Error Blink Status, it is advisable to use the ZapView
®
430 software
to troubleshoot the problem. If not already installed on your computer, the current version of the software
can be downloaded from www.micronor.com
.
3.6 System Start-Up Without PC Computer
It is recommended to use a PC (laptop) computer when making the MR430 Position Sensing System
operational. Micronor provides the ZapView® software for setting parameters and performing diagnostics
of the system. Checking the system after installation with ZapView® provides assurance that the installation
is complete and the system functions perfectly.
There may be instances where no PC is available. Installations that use only the analog or SSI outputs, do
not require specific programming on-site, especially if the MR430 controller was pre-configured for the
customer's application at the factory - or the customer is using the default settings.
Install the sensor as described above, connect the fiber optic lines, and apply 24V to the MR430 controller.
Rotate the sensor through at least one full revolution. If the power LED remains ON steady state, it means
that all tests internal were completed successfully and the system is ready to go.
All that is left to do is to set the Home (Zero) position. Bring the system to the desired Home position, and
activate the recessed Home button located below J1, as shown in the figure below.
Note:
In case of an error, the LED power light will blink a specific error code. The first press of the Home
button will acknowledge the error signal. The second press will secure the Home position. (Pressing the
switch twice will always Home the unit.)

3.7 Functional System Overview
The MR430 system consists of an all optical, non-electrical, passive sensor (MR431) which is connected to
the MR430 Controller via a duplex POF and POIF fiber assembly.
The MR430 Controller constantly interrogates the sensor by sending a short optical pulse to the sensor.
The sensor impresses a code corresponding to the actual shaft position on to the imaging fiber. The
MR430 controller receives this optical image and through computational algorithms determines the
absolute shaft position. The system is a “Single Turn Absolute” position sensor. However, the controller
provides mechanism which enables the system to function quasi multi-turn position sensor.
Figure 9 provides a block diagram of the MR430 system and its user interfaces. The single-turn resolution
is 13 bits and there is also a 12-bit turn counter which keeps track of the full turns of the sensor while the
unit is powered up and the sensor is connected with the fiber optic link. Absolute single-turn position (13
bits) and turn counter (12 bits) combine to provide a 25-bit position signal. The user has the option to
mask the turn counter and thus limit the output to match the physical setup. If the sensor is only used to
measure a range over , let’s say, 5 turns then the user may limit the turn counter to 3bits providing a range
of maximum 8 turns until the output wraps around back to zero. Using the example above, the readout
would be limited to 16bits (0 to 65,535) to cover the position range of (3 turns times 8192 resolution per
turn) 24,575 counts
As the block diagram shows, the position signal is routed to all the various output interfaces built into the
unit and position information is available simultaneously.

The Serial Interface conforms to the Modbus/RTU standard and is the main communications interface, ify
specifically for setup and configuration purposes. To simplify setup with a PC, a USB interface is also
provided.
The SSI interface (available at J3 on the bottom of the unit) is often used to interface with PLC controllers
and other automation equipment. This output toggles out fixed 25 bits and derives its information after
the turn-mask. Therefore maximum read-out values are restricted to what the turn-mask is configured to.
By definition, the SSI outputs only positive values. When the sensor rotates counter clockwise through
zero, the reading will go from 0 to the maximum possible readout value defined by the turn counter. If,
for example, the turn counter is set to 1, that means the maximum readout is 2
(13+1)
-1 = 16,383. The output
reads 2,1,0, 16,383.
The Current Output is a fully isolated 4-20mA loop powered output. It has three programmable operating
modes plus scaling over the full range of 25 bits. Digital to analog output resolution is 13 bits.
The Voltage Output provides voltage from -10V to +10V. It has four programmable operating modes plus
scaling over the full range of 25 bits. Digital to analog resolution is 12 bits plus sign.
One digital Set-Point output provides a Limit Switch-like behavior. This output can be programmed to turn
ON or OFF at a specific position with the full 25-bit range available. This output is a 5V logic level.
One external input is provided to Set the programmable Home position (usually zero). When this input
goes Hi, the position is set to the user programmable home position.
There is an Auxiliary input available for special custom functionality uses. Contact Micronor sales if a special
input function is required.
ZERO (HOME) Button Functionality
The ZERO or Homing button is located just below J1 connector.
• Manual Sensor and Controller Pairing (see Section 3.6)
• Set Current Position to ‘0’ or “HOME” location (see Section 3.6)
• Clear Error LED Codes (see Section 3.6)

3.8 Turn-Counter and Turn-Counter Size
The MR430 controller keeps track of the turns using a 12bit counter. The 12 bit counter is combined with
the 13 bits of single-turn position information for a total of 25 bit position information. That arrangement
allows for up to 4096 turns with a resolution of 13 bits is a maximum position range of 33,554,432. Most
real world applications do not require this kind of measurement range. Therefore the user may want to
limit the number of turns that the sensor keeps track of. The size of the turn counter is controlled by the
user programmable ‘Turn Counter” variable. This number defines how many bits deep the turn counter is
counting until it rolls over back to zero. Please note there are no negative position numbers, all position
number are positive.
Example:
The application needs to measure a position over 12.4 turns. The next binary number is at 16 and therefore
the turn counter should be programmed to count to at least 16 turns. For this to take effect set the turn
counter variable to 4, because 2
4
equals 16. Only the first 4 bits of the turn counter are now activated.

3.9 Multi-Turn Operation
The MR430 controller accurately counts each turn while the system is powered and the remote sensor is
connected. Under these conditions multi-turn operation is possible.
If remote sensor is disconnected and the sensor position is moved past the zero point, then the turn
counter is no longer synchronized with the actual position. Similarly, if the power to the controller is lost,
then the sensor can no longer keep track of turns.
However, for a quasi multi-turn operation, the MR430 saves the last position, including the turns count,
just as the electrical power is removed from the unit. Often the application is such that when power is lost,
no further movement of the sensor is possible. Under these circumstances, the user may elect to have the
MR430 controller restore the turns upon power-on. To safeguard against erroneous position restoration,
the MR430 controller compares the new start-up single-turn position with the position saved at power
down. If that comparison falls within a user defined range then the turn counter is restored. Together with
the absolute single-turn position the actual multi-turn absolute position is retained in case of a power
outage.
Note
: User must decide if a quasi-Multi-Turn operation is feasible and appropriate.
3.10 Battery Backup for Multi-Turn Operation
The quasi multi-turn operation as described in the previous section is not fail-safe. A better method is to
use a Battery backup and keep the unit powered up even over prolonged power outages. The low power
consumption of only 60mA makes this feasible.

3.11 SSI Interface
Figure 11. SSI Interface Connector – J3 (10 pin).
The SSI interface is configured as Slave and the Master must supply the clock. The clock maybe in the
range from 25kHz to 250kHz. The user should also set the MR430 with the appropriate clock rate. This will
allow the MR430 to provide correct timing for repeat read' mode on the SSI bus. If not sure how to set the
SSI baud rate leave it at the lowest setting of 25k baud, this setting will work fine in most applications.
Reading position packets at higher than 4 kHz is not recommended as the update rate of the MR430 is
1.2kHz. Reading at higher intervals will not add more information.
Termination Resistor
For long link length and high clock rate it may be necessary to terminate the Clock line at the MR430 in
order to avoid reflective signal interference. The user must install that resistor external to the MR430. (For
OEM customers please consult MICRONOR as this resistor may be added inside the controller)

SSI Single Transmission
The diagram in below illustrates a single data transmission using SSI protocol:
Figure 12. SSI Single Transmission Timing
The SSI is initially in the idle mode, where both the data and clock line are high. The transmission mode is
evoked when the master initiates a train of clock pulses. Once, the slave receives the beginning of the
clock signal (1), it automatically freezes its current data. With the first rising edge (2) of the clock sequence,
the MSB of the sensor’s value is transmitted and with consequent rising edges, the bits are sequentially
transmitted to the output. After the transmission of complete data word (3) (i.e. LSB is transmitted), and
an additional rising edge of the clock sets the clock line to go HIGH. The data line is set to low and remains
there for a period of time, tm, to recognize the transfer timeout. If a clock signal (data-output request) is
received within the time, tm, the same data as before will be transmitted again (multiple transmission).
The slave starts updating its value and the data line is set to HIGH (idle mode), if there are no clock pulses
within time, tm. This marks the end of single transmission of the data word. Once the slave receives a clock
signal at a time, tp ≥ tm, then the updated position value is frozen and the transmission of the value begins
as described earlier.

3.12 Voltage Output
The analog output voltage is derived from the position signal and maybe freely scaled by the user. There
are four distinct modes:
Mode 0: OFF, voltage is always 0
Mode 1: Single-turn 0V to +10V
Mode 2: Scalable 0V to +10V
Mode 3: Scalable -10V to +10V
Figure 13. Mode 1 Voltage Output
MODE 1 automatically sets the Scale to 8192. It outputs 0V when position is 0 and +10V when
position is 8191. Output wraps around back to 0V when one turn completes. This wrap around
occurs regardless of the Turn Mask setting.
Figure 14. Mode 2 Voltage Output
MODE 2 lets the user program the output voltage based on a scale value. The output is 0 when the position
is 0 and will reach +10V when the position reaches the scale value. The full 25-bit range is available for
scaling.
When setting this mode up the user should also take into account what should happen when the position
reaches maximum or minimum values. The MR430 system determines the wrap-around point based on
the available position range, which is based on the turn mask setting n. The Count
max
is then 2n
The wrap point P
w
is determined based on the formula above. Essentially, it is the midpoint between the
unused range.

Figure 15. Mode 3 Voltage Output
MODE 3 is very similar to mode 2 but it makes use of the negative output voltage capability of the MR430.
The output voltage follows the position output with 0 position being -10V and when the Scale value is
reached the output is 0V and with position twice the scale value the output is +10V. Mode 3 is ideal when
the voltage should swing positive or negative around a predetermined home position. In that case the
Reset Value of the MR430 should be set to the same value as the scale. When the sensor is in the home
position, it is then equal to the scale value and the voltage output will be 0V. When the sensor turns CCW,
the voltage will start going negative, and, vice versa, when the sensor turns CW the voltage will go positive.
As in mode 2 the system also determines a wraparound point based on the turn counter setting.
The Wrap point Pw is in the middle of the unused range of the senor. The maximum position range is
determined by the Turn Counter setting.
Output Frequency
The voltage output follows the position in real time with a delay of approximately 800us from when the
actual position was reached. The update rate of the D/A converter is 850us.

3.13 Isolated Current Output (4-20mA)
The isolated current output is derived from the position signal
and may be freely scaled by the user. Since the output is
isolated from the rest of the circuitry, it must be loop
powered:
There are three selectable output modes:
Mode 0: OFF, current is less then 300uA
Mode 1: Single-turn 4mA to 20mA
Mode 2: Scalable 4mA to 20mA
Figure 17. Isolated 4-20mA Connection
Figure 18. Mode 1 Current Output
MODE 1 automatically sets the Scale to 8192. It outputs 4mA when position is 0 and 20mA when position
is 8191. Output wraps around back to 4mA when position changes from 8191 to 0 at the completion of
one turn. This wrap around occurs regardless of the Turn Mask setting.

4. Serial Communication – Modbus
Integration with a PLC or other host computer within an automation system is via the Modbus compatible
serial interface. Obviously the main purpose is to query the MR430 controller for position information
which is accomplished by reading Register 0x001. In most cases, it is recommended to also include the
status information registers 0x000 with the position register 0x001 for the same read request.
In addition to the position register the MR430 provides a host of auxiliary functions and parameter settings
that the user may choose to utilize. All the functions and parameter settings maybe programmed by the
PLC during system initialization. An alternate way is to pre-configure the MR430 using the MICRONOR
provided ZapView® software and permanently store all the parameters in the EEPROM. Specifically, an
individual configuration of the MR430 controller is required when a specific Modbus address need to be
preset before connecting the controller to the Modbus.
To access these functions and to familiarize yourself with the functionality of the MR430 controller we
recommend to use ZapView® software, which is supplied with the unit. To run ZapView®, you must have
a Personal Computer available with a USB interface. If a USB interface is not available then a serial interface
plus the Micronor RS232-to-RS422/RS485 converter cable model MRS232-1 (must be purchased
separately) maybe used.
4.1 USB-Serial Emulator
The MR430, being Modbus compatible, must communicate via a serial interface, thus the USB interface
utilizes the Future Technology Devices International (FTDI) interface chip www.ftdichip.com
. This chip
communicates via USB, but within the PC emulates a serial COM port. When ZapView® is installed, the
appropriate FTDI driver is installed on the PC. The conversion from USB to Serial is essential to keeping
the communications protocol Modbus compatible.
Even when communicating via USB the MR430 controller uses the actual baud rate and bus address
settings. The baud rate of the PC’s COMx port must therefore be set to match the baud rate of the MR430
controller.
DEFAULTS
The default bus address of the MR430 controller is 235.
The default and recommended baud rate is 57,600 baud, 8bits, 1 Stop, No Parity

4.2 Serial Interface Specification
• RS-422/RS485 Duplex addressable bus interface
• Baud rate programmable: 9,600 / 19,200 / 38,400 / 57,200 or 11,5200 baud
• 1 Start Bit
• 8 Data Bits
• 1 Stop Bit
• no parity
Factory Standard Modbus Address is set to 235 (Hexadecimal 0xEB)l.
When not using a USB interface, the optional MR232-1 Interface cable may be connected directly to a PC
Computer via standard RS232 and DB9 connector. In that case the maximum baud rate is 57,600. The
MR232-1 Interface cable converts the RS232 signals to the RS485 compatible signals of the MR430.

4.4 Serial Bus Termination Resistor
The Serial Interface of the RS485 interface internally “open”, it does not have a termination resistor inside.
The user must add this resistor externally if so required.
Since this is a fiber optic sensing system, it is expected that the Controller is always located nearby or
within the same control closet where the position signal is required. Long electrical link lengths should
thus be avoided.
4.5 MODBUS Communications Protocol
The communications protocol follows the Modbus RTU (binary) protocol. A number of commands allow
for configuring the operational parameters of the MR430 while other commands are specifically meant for
diagnostics used during setup, maintenance and troubleshooting. The status and position readout
registers are intentionally arranged in sequence for a quick readout while system is in operation mode.
The format for the commands and responses in general follow the MODBUS RTU specification, with the
exception that not all registers maybe combined within one readout sequence. See table below for
allowable register combination.
MODBUS information can be obtained at: www.Modbus.com
What Is ZapView®430 Setup Software?
MICRONOR provides ZapView®, a user friendly setup program free of charge along
with the purchase of the MR430 system. ZapView® runs on Windows 10 and requires
Microsoft .net Framework 4.0 to be on the machine.
Please refer to section x.xx for detailed information.
Unless you plan to connect the MR430 to your own PLC or computer equipment for
real-time data retrieval, there is no need to become familiar with the Communications
protocol described herein.
Framing
Message frames are separated by a silent interval of at least 3.5 character times. If a silent interval of more
than 1.5 character times occurs between two characters of the message frame, the message frame is
considered incomplete and is discarded.
A 16bit LRC/CRC Frame Check follows the message.
Device Address Selection:
The MR430 comes pre-configured with Device address 235
The MR430 always listens to address 235 (Broadcast Address). To re-program the device address, send
desired new address via command FC10 to register 0x104 via the broadcast address (235) and then send
the appropriate “STORE EEPROM” command via FC52 register. Upon executing this procedure, the unit
will listen to the newly assigned Device Address and the Broadcast address 235.
In a bus system do NOT use the Broad cast Address 235.

In ZapView®, select tab page “System Info” and enter the desired new bus address
and hit <enter> key. When the red “Save to EEPROM” button pops up push this
button and the new address is stored in the MR430 controller.
REGISTER NUMBERS VS. METER ADDRESSES
In this instruction manual all register are referred to by their address i.e. starting at 0.
Some Master devices (e.g., Modicon) require that the desired Register Number and not the Register
Address be entered. The Register Number is 1 higher than the Register Address. For entry to these
devices, add 1 to the Register Address shown in the tables below. The Register Address shown will then
be output from these devices.

5. MR430 - Error Handling and Troubleshooting
5.1 Explanation of Status and Error Handling
The MR430 incorporates a sophisticated integrity monitoring, error and failure reporting system. There
are four Error Groups:
1. EEPROM
At start-up the EEPROM checksum and EEPROM data integrity are checked.
2. Power Supply Voltages
At start-up the applied power supply voltage (24V) and internal voltages are checked. If they fall
outside the required value, errors are logged and reported. These voltages are evaluated once at
system power-up. Subsequent voltage changes will not be evaluated.
3. Sensor Read Error
• Low optical power
• Position read error
• Restore Value out of Range
4. Communication Errors
Communication errors are flagged by the underlying Modbus drivers. However, Modbus standard
does not specify a data integrity test. This is where the MR430 allows the user to query the Status
byte after each transmission to verify if the provided data was within the appropriate range etc.
5.2 Explanation of Status and Error Indication
When an error occurs the System Status Word is set with the associated Error Code (Register 0x00). When
more than one error at the time occurs then the error code is stacked up in order of its priority.
Each Error has an associated error counter. The user may request all error registers for examination through
a request to Register 0x040. MODBUS Function Register 0x40, Reads all 24 Error Registers Sequentially
Table 1 lists all the status and error report possibilities.

All errors get logged but may not necessarily provide visual indication. The user should take necessary
action based on the severity level of the reported status/error.
3
= System will no longer work without a remedy.
2
= Important, problem should be fixed but system may still be partially operational
1
= Benign, system keeps on working fine
After examination the user may clear the Error Indication by issuing the Function Call FC5 to coil number
5. This will clear the indicated error in the Status byte. If there are more errors stacked up, then the next
highest priority will be displayed.
While there is an error Indication The Zero push button will also clear a pending error indication. The user
must be careful to only push the button once and wait and check if the error indication. Because once the
error is cleared the button will assume it’s normal function as a Zero Point switch.
Some errors are cleared as soon as normal operation is established. For instance when the sensor is
disconnected or a high loss in the optical connection occurs then an error is reported and the PWR LED
will blink. However, when the optical connection is re-established then the error will clear itself without
user interaction.
Some errors are not sufficient cause of a problem and therefore they are logged and indicated by a short
blink on the PWR LED and then will clear themselves. For instance, if the 24V power supply deviates by

5.3 Reading the Error Counters
The entire packet of all 24 error counters may be read by issuing MODBUS command to Register 0x040
with a register count of 24. The sequence of registers is according to the error number in Table 1 in
ascending order.
Each register is a 16-bit word. If the most significant bit is set to a logical one, this indicates that there is
an active error residing in the Status stack.
The remaining 15 bits indicate the number of errors that occurred since power was applied to the unit.
The user may clear all error counters by issuing Function Call FC5 coil #6.
5.4 About Statistical Read Error Determination
The errors Sensor 1024 and Sensor 65000 are error rates that are measured by error occurrences within a
time period. If more than one error occurs within the specified time period, then an error is logged. The
time period is the number of samples times 850uS. 1024 x 850us = .87 seconds
65000 x 850us = 55 seconds.
Note: T1 and T2 are sample counters
The following algorithm is used to detect the errors:

8. MR430 Theory of Operation
Figure 20. Block Diagram of the Fiber Optic Position Sensor System
The functional block diagram shows the two main components The Sensor is connected by a duplex fiber
optic cable. The Transmit fiber guides an optical pulse from a red LED to the position sensor. A second
Receive fiber returns the light with the embedded position information in the form of a specific unique
light pattern impressed on to the imaging fiber.
The optical image of the returned light pattern is unique to any given position of the sensor. This light
pattern is imaged to a linear CCD sensor which converts the optical pattern into an electrical
representation of the position pattern. The firmware algorithm extracts the position information, converts
the position into digital words, and exports the position information over the selected output interface Modbus RTU or SSI interface (serial synchronous interface).
