M – red diode – full internal memory indicator or writing file
to SD/SDHC memory indicator, when the internal
memory usage exceeds 95%, the diode is
constantly on, if the transducer operates
with an installed memory card, then the LED flashes
when data is being written on the card.
A1 – red diode – indicator of switching on the first alarm
A2 – red diode – indicator of switching on the second alarm
or 24V d.c. power supply
Power indicator – green diode.
5.2. Messages after switching on the power
After connecting external signals and switch the power supply
on which is signalled with a green LED (power indicator), the transducer displays the type, current firmware version and the serial number.
If the transducer is equipped with Ethernet interface (P30U-X2XXXXXX)
IP address is displayed after serial number (stored in memory or received from the DHCP server).

After about five seconds, the transducer automatically
switches to operating mode; it makes a measurement and converts it
into an analog output signal. It displays the measured value in the top
row of the display and auxiliary information in the bottom row of the display (section 5.5.4). The LED indicator signals the transmission status
on the RS-485 interface, status of the internal memory use and alarm
states. If transducer is equipped with an Ethernet interface, Ethernet
services start-up: WWW server, FTP server, TCP/IP Modbus

5.5. Transducer functions
5.5.1. Measurement input
The P30U transducer is equipped with universal, configurable
measurement input, which enables to measure direct current, direct
voltage, resistance and temperature from thermocouples and thermistors. Detailed information about supported inputs is shown in table 48.
Input type RS-485 is a special type of input, in which transducer treats
value form register 8000 as a measured value. Value in register 8000
depends on RS-485 interface working mode (Slave, Monitor or Master)
and can be written, monitored or read via RS-485 interface.
5.5.1.1. Interface RS-485 Master mode
RS-485 interface can work in Master mode, in which device
is able to read data registers from one slave device connected to transducer. Both devices must have the same communication parameters.
The RS-485 Master mode is switched on by selecting the appropriate
mode of RS-485 interface from menu: Mbus 485 → Mode →
40
Master or by entering value „2” into the register 4042.
In the Master mode the following parameters should be configured
in the Mbus 485 menu:

No.OfErr
Admissible number of incorrect responses to the transducer request (number of repeated requests before
an error is displayed)
The parameters (4 - 6) may also be configured by RS-485
(registers 4048- 4052) before the RS-485 Master mode is selected.
After selecting the RS-485 Master mode it is impossible for other
Master device to poll the transducer.
All values read in Master mode are available as a floating
point values in registers from range 8000...8049., first red out value is
placed in register 8000, second value in 8001 register etc.
In the transducer Mbus 485 menu there is the parameter No.ofErr,
which defines the admissible number of incorrect responses
to the transducer request (number of repeated requests before
an error is displayed). That parameter is also modified by RS-485 (register 4005) before the RS-485 Master mode is selected. If input type
Input → RS-485 is selected, the first register being polled is
41
treated as the measured value (register 8000). If the request refers
to a larger number of registers (parameter No.ofVal > 1 ), then it is
possible to display, at the bottom row of the display, the value of other
register than the first one being polled, because all the polled registers are copied to the block of registers from the range 8000...8049.
For example, when we want to display additionally the value
of the second register being polled, we should set the value “8001”
in the menu of the parameter Display→ Disp.Reg. (the first
value being polled is in the register 8000 and it is treated as the main
displayed value) or enter the value “8001” into the register 4024.
In order to make the transducer RS-485 interface work again
in the Slave mode, one should select proper mode in menu RS-485
Mbus 485 → Mode → Slave.

mode to read and register relative humidity from a P18 transducer.

5.5.1.2. Interface RS-485 Monitor mode
RS-485 interface can work in Monitor mode, in which
device is able to listen to traffic in the RS-485 network and react to specific register of responses of the selected device. The P30U transducer
must have the same communication parameters as the device being
listened to. The RS-485 Monitor mode is switched on by selecting
the appropriate mode from menu: Mbus 485 → Mode → Monitor
or by entering the value “1” into the register 4042.
In the RS- 485 Monitor mode the following parameters should be
configured in the Mbus 485 menu:

The parameters (4 - 6) may also be configured by RS-485
(registers 4048- 4052) before the RS-485 Monitor mode is selected.
After selecting the RS-485 Monitor mode it is impossible for other
Master device to poll the transducer.
Similarly as in the RS-485 Master mode the registers being
listened to are copied to the register area from the range 8000...8049.
The first register being listened to is copied to the register 8000 and it can
be treated as the main displayed value. If the parameter No.ofVal > 1,
then the values of the following registers being listened to reach the following registers from the range 8000...8049. For example, when we want
to display additionally the value of the third register being listened to,
43
we should set the value “8002” in the menu of the parameter
Display
→
Disp.Reg. or enter the value “8002” into
the register 4024.
In order to make the transducer RS-485 interface work again
in the Slave mode, one should select proper mode in menu RS-485
Mbus 485 → Mode → Slave.
5.5.1.3. Median filter
Median filter function on measured value is implemented
in Transducer P30U. This function enables to filter input signal from influence of perturbances on input signal. Parameter Input → Median
specifies number of samples from which signal will be filtered - number
of samples determines filtering period. For example, if transducer is configured for measuring voltage from 0...10 V range (sample rate 80 ms) ,
median function is off and sequential measured samples are: 10.0065,
10.0055, 10.025, 10.004, 10.0055, then the output value will be unstable
and average value will have value 10.0093. Average value does not
describe the real level of considered signal what is shown on fig. 10.
Fig.10. Exemplary signal – samples unsorted
44
After switching median filter on with number of samples 5
(sample rate 80 ms) 5 subsequent samples will be sorted and only
median sample will be treated as measured value (sample no 3 after sorting). After sorting Xn values are as follows: 10.004, 10.0055, 10.0055,
10.0065, 10.025.
Fig.11. Median filter operation – sorted samples
Value X3 = 10.0055V will be treated as a result of median operation
in this example. Average value after switching the median filter on will
also have value X3 = 10.0055V. The highest value of perturbations on
measured signals the highest number of median samples should be
applied from range 1...50. If number of median samples is set to „1”
median operation is switch off. If an even number of samples is chosen, average of two median values will be given as a result of median
operation.
45
5.5.1.4. Averaging time
Various averaging time of the measured value can be defined
in transducer P30U. Averaging time of measured value can be
set within 0.075...0,2...20 s range – the moving window averaging
function has been used. The minimal time below 0,2 s can only be used
for input types: Voltage -10..10V, Voltage -24..24V,
Current -20..20mA.
5.5.1.5. Maximum and minimum values of measured signals
The P30U transducer has been fitted with the function
of storing minimum and maximum value with the time and date
of occurrence. Minimum and maximum value are stored after a power
supply loss, they can be read and reset using transducer registers
via Modbus protocol (RS-485, TCP/IP – see table 37, WWW server,
they can also be displayed on the display using the following keys:
- the maximum value,
- the minimum value.
Erasing the minimum and maximum value is possible via keypad after
pressing the combination of
and
.
5.5.1.6. Mathematical operations on measured values
The transducer enables the performance of additional mathematical operations on the measured value. The following mathematical
operations have been implemented in the transducer:
•
mathematical functions,
•
21-point individual characteristic,
•
display range limit (main input only).
The way in which the mathematical operation influences the measured
value is shown at fig. 12. Switching on and selection of the mathematical
operation is possible via the keypad, Modbus protocol (RS-485, TCP/IP)
and WWW server.

5.5.1.7. Mathematical functions
The P30U transducer can calculate the measured values
using one of 5 implemented mathematical functions:
•
square of measured value,
•
root of measured value,
•
inverse of measured value,
•
inverse square of measured value,
•
inverse root of measured value.
The operation of mathematical functions is switched off by default.
5.5.1.8. Input individual characteristic
P30U transducers perform the function of conversion
of the measured value to any value due to implemented function
of individual characteristics of the input. Independent individual characteristics have been implemented for the main input and the auxiliary input.
The individual characteristics rescales the input signal being measured
according to the characteristics set. The user can enter a maximum
of twenty functions each by specifying points determining the ranges
and expected values for subsequent points.
Programming individual characteristic consists in the definition
of the number of points which the input function will be linearized by.
Note that the number of linearized functions is the number of points
minus one. Next, one must program subsequent points by providing
the measured value Xn and the expected value corresponding to it –
the value to be displayed (Yn). The visual interpretation of the individual
characteristic is shown on fig. 13.
48
Input function
Linearized function
Measured value
Fig.13. Input individual characteristic
During function approximation, one must remember that
in the case of approximating curves that significantly deviate from linear
characteristics, the higher number of linearising sections, the lower
the linearisation error.
If the measured values are lower than X1, then the calculations will be made based on the first straight line calculated based
on points (X1,Y1) and (X2,Y2). However, for values higher than Xn
(where n – the last declared measured value), the displayed value will
be calculated based on the linear function determined last.
Note: All the entered points of the measured value (Yn) must be arranged in ascending order, so that the following dependence is true:
X1<X2<X3…<Xn
If the dependence specified above is not true, the individual
characteristic functions will be automatically switched off (will not
be performed) and a diagnostic flag will be set in the status register.
Individual characteristics are switched off by default. Parameters
of individual characteristics can be configured via keyboard as separate
groups of sub-menu: Ind.Char.
49
5.5.1.9. Displayed value range limitation
The value range limitation applies only to the main input,
so that it influence only the displayed value DisplVal. The value
range limitation parameters are located in the menu in the group
of Display parameters: Over Lo – lower display value threshold
and Over Hi – upper display value threshold. The default value
of upper overflow is 99999 , and for lower overflow -99999.
If the lower display overflow occurs the vvvvvv , symbol is displayed on the display and the number value of the displayed value is
set to -1e20. If the upper display overflow occurs the
symbol
is displayed on the display and the number value of the displayed value
is set to +1e20.
5.5.2. Analog output
The P30U transducer is equipped with one current type
(source) or voltage type analog output depending on the variant code.
5.5.2.1. Analog output individual characteristic
The P30U transducer enables processing displayed value,
second displayed value and the real time clock value into analog
output signal based on the individual linear characteristic
of the analog output. On the basis of coordinates of two points
provided by the user, the transducer determines (using a system
of equations) a and b individual characteristic coefficients.
where X1 in and X2 in – the displayed value,
Y1 out and Y2 out – expected value on the analog output.

5.5.2.2. Analog output overflow management
In P30U transducer user can additionally configure
the behaviour of the analog output after controlling output value overflow. By default, overflow management is switched off – in such a case,
after controlling output value is overflowed, the output is still controlled
proportionally to the controlling output value outside the basic range
of the output. After the overflow management is switched on,
the user can define the value to control the output after the occurrence
of the upper or lower overflow of the controlling output value.

5.5.3. Alarm and power outputs
The P30U transducer is equipped with 2 relay alarm outputs
with a normally open contact or with 1 relay output with a normally open
contact and 1 power supply output 24 V d.c. (depending on the manufacturing variant code). Each alarm (power supply output 24 V d .c.
should be treated similarly to the alarm) can operate in one of six
modes. Fig. 17 shows alarm operation in the following modes: n-on,
n-off, on, off. Two remaining modes: h-on i h-off mean, respectively,
always on and always off. These modes are intended for manual simulation of alarm states.
In case of the transducer variant with 24 V d.c. output,
the second alarm mode should be set to h-on, in such a case,
the auxiliary power supply output will be constantly switched on.

5.5.4. LCD display
The P30U traducers are equipped with a backlit LCD display
consist of two lines of 8 characters each. The top line of the display is
used for presenting the displayed value in floating point format (5 digits)
and for displaying the SD/SDHC card or internal file system memory status pictograms, or maximum or minimum value pictograms after pressing
or
keys.

5.5.4.1. Custom unit definition
In the transducers of the P30 family, apart from the defined
standard units, it is possible to define user own unit to be displayed
in the lower line of the LCD display. The maximum size of the unit
field is 5 characters, each character consists of 8 lines which makes
5x8 = 40 fields (registers) that define the unit. Custom unit has been
defined in the transducers by default - the LUMEL logo. In order
to display the custom unit, enter “57” in register 4020 or select the unit
from the transducer menu.
To define a custom unit, use registers from 4400 … 4440
range. The following figure presents the method of defining the unit.

5.5.4.2. Displaying two values with their units
P30U transducer enables displaying two different values
witch their units - displayed value at the top row of display and the second displayed value (value of any transducer register) at the bottom
row of the display. It is possible to display both values with their units.
The displayed value unit is chosen from menu Settings → Display
→ Unit(register 4020), and the second displayed value unit is chosen
from menu Settings → Display → Unit 2 (register 4023).
Displaying two units is only possible when on the bottom row of display is
displayed second displayed value marked with
60
sign.
Fig.19. Algorithm of displaying two values with their units
5.5.5. Writing and reading transducer configuration from file
P30U-X1XXXXXX and P30U-X2XXXXXX manufacturing
variants of P30U transducers enable storing and reading configuration
from the file located on an external SD/SDHC card or in the internal file
system memory.
5.5.5.1. Storing the transducer configuration file
To store the current transducer configuration, select
option:
Service → SaveFile → Yes, from the menu
or enter “1” in register 4077. The text file with configuration
will be saved to P30U, folder, file name: P30U_PAR.CON
(section 5.8.4. Fig. 27. ). Any subsequent saving the configuration file
will overwrite the current file.
5.5.5.2. Reading the transducer configuration file
Reading the transducer configuration from file enables quick
configuration of the transducer equipped with an external SD/SDHC
card or internal file system memory. The configuration file should be
located in P30U folder and its name should be P30U_PAR.CON.
The file can be generated by a properly configured P30U transducer or by eCon software (Modbus RS-485 or TCP/IP). In case of
transducers in P30U-X2XXXXXX manufacturing variant, the file
61
can be moved from one device to another using the FTP protocol.
In case of P30U-X1XXXXXX manufacturing variants, a single external
memory card can be used to transfer configuration to multiple transducers equipped with external SD card slots.
To force parameter update from file, switch on the transducer
while pressing
key. If the configuration file contains appropriate data and the new configuration is accepted, the following message
will be displayed on the transducer display:
Fig.22. Message confirming successful readout transducer
configuration from file.
If the parameter update from file is forced and a proper file is missing
or existing file contains corrupted data (at least one corrupted
parameter), the current configuration will be maintained and the following message will be displayed:
Fig.23. Message informing about an unsuccessful readout
transducer configuration file.
5.6. Default settings
Default P30U transducer settings have been provided
in table 17. These settings can be restored using transducer menu by selecting Settings Service → Fabr.Par → Yes or via RS-485
interface by entering “1” in register 4055.

5.7. Firmware update
P30U transducer enables firmware update by user using
PC computer with eCon software installed. The free eCon software
and update files are available at www.lumel.com.pl. RS-485 to USB
converter, e.g. PD10 converter, is required for proceeding with the update.
Fig.24. Screenshot of the software for updating transducer
firmware.
Note! After firmware update, default transducer
settings must be set, therefore it is recommended to store
the transducer parameters before starting the update
process using eCon software
67
After starting eCon software, set the rate, mode and transducer address, as well as the RS-485 interface port in Communication tab. Next, click connect icon and read all transducer parameters
(required for restoring them later). Then, click Update firmware
link which will call LUMEL UPDATER (LU) software dialog – fig. 24.
Check transmission parameters using Setup button and press
Connect button. Information about the update progress are displayed
in Messages box. If the port is correctly opened, Port opened information is displayed. There are two methods of entering updating mode
in the transducer: remotely via LU (based on eCon settings – address,
mode, rate, COM port) or by powering the transducer on while holding
down
key – update using default communication parameters, i.e. rate 9600 kb/s, mode 8N2, or while holding down
- key - update using recommended communication parameters,
i.e. rate 115200 kb/s, mode 8N2. If all indicating LEDs are on
and the display shows Connect UPDATER message, transducer is
ready to connect with computer.
If the transducer establishes
communication
with
LUMEL
UPDATER
(LU)
software,
Device found: P30U message and the version of the main firmware
and bootloader will be displayed, as well as the Device is ready
message will be shown on the transducer display. Next, press “...” button
and read the file with the new firmware version in LUMEL UPDATER.
If the file opens properly, File opened information will be shown
in the LU software window. Press Send button. During the update
process, the indicating LEDs are switched on in a sequence,
and the percent progress of update is shown on the lower line
of the display. After a successful update, the transducer restarts
to normal operation, whereas Done message and update duration are
displayed in the information box (LU).
The current firmware version can also be checked by reading
the welcome messages of the transducer after powering it on.
68
Note: Updating the firmware is only possible when
the transducer and a PC computer are connected
directly (no other Master devices can be connected using
the RS-485 interface).
Note: Switching off the power supply during the firmware
updating process may result in an unrepairable damage
to the transducer!
5.8. Archiving measured values
5.8.1. Transducer memory structure
Standard P30U transducers (regardless of the manufacturing variant code) are equipped with a 4MB internal memory for storing
data recorded by the transducer. The default recorded parameter is
the displayed value, that is the measured value or value converted using
mathematical functions and individual input characteristic. It is also
possible to additionally record the second displayed value or displayed
values and all queried values if RS-485 interface works in Master
or Monitor mode. The internal transducer memory enables storing
534,336 records. The memory is of circular buffer type. After the memory becomes full, the oldest data is overwritten. The internal archive can
be read, copied and cleared.
Transducers in P30U-X1XXXXXX variants are equipped
with an SD/SDHC memory card slot enabling writing archive data to files
on the external SD/SDHC memory card.
Transducers in P30U-X2XXXXXX variants are equipped
with an 8GB internal file system memory (the capacity of the file system
memory can be increased on a special order or due to manufacturer’s
needs) where the data from the internal memory are automatically
copied to files. Data can be downloaded via the Ethernet interface using
the FTP protocol.
69
Note:
Changing the Archive → Arch.Val parameter
value in the menu will delete the archive
in the internal memory!!!
5.8.2. Internal memory
The internal transducer memory is divided into 8,192 pages.
Each memory page can store 66 archive data records. Records
on the page always begin from the page beginning and occupy
the entire space of the page. Each memory page contains 528 bytes.
The memory is divided into two areas: the first 8,096 memory pages
are for the primary archive memory, whilst the last 96 pages are intended for reserve archive used during the operation of copying of archive
to the SD/SDHC card or the file system internal memory. (total memory
is 8,096*528B + 96*528B = 4,275,312 Bytes).
The beginning of the archive data is defined by the number
of the page on which there is the first record of the archive
and by the initial byte which defines from which page byte the first record begins. The end of the archive is defined similarly by the number
of the page on which there is the last record of the page on which there
is the last record of the page and the byte where recording of the next
archive record will begin.
Erasing the content of the archive internal memory is done
by assigning parameters of the archive end to the archive beginning.
Due to this operation, in case of deleting the archive,there is possibility
to restore the memory content.
Data in the archive internal memory are stored as records
consisting of 8 bytes. The current state of internal memory use can be
indicated on the LCD display after selecting the function of displaying
the unit with the indication of the internal memory use status at the lower
line of LCD display. Table 18 describes the meaning of the internal
memory status indicator.

5.8.2.2. Downloading archived data from the internal memory
Downloading of archive data from the internal memory is performed via the memory card (option) or via the RS-485 interface. Downloading data consists in reading subsequent memory pages containing
data records. eCon software enables acquiring individual pages from
the internal memory.
If the transducer has been manufactured in a variant supporting external SD/SDHC cards, then the archive data can automatically
be copied to the memory card (this is the fastest method of obtaining
72
archive data). To do this, insert the SD/SDHC card in the transducer
slot (contacts facing down) and make sure that the card has been
properly mounted (the top right corner of the display shows
). The percent value of archive use, at which the data
a card icon
will automatically be copied to the card or to the file internal file system memory, must be set. This value is placed in register 7614 or can
be changed using menu: Archive → Param.SD. For example if
“20.0” is entered in register 7614, data will be collected in the internal
transducer memory until the use of the internal memory reaches 20%,
then the automatic archive copying to the SD/SDHC card or the file
system internal memory process will begin. If the percent value of use
will be higher, e.g. 99%, then data will be written on the SD/SDHC card
less frequently, but the writing process will take longer. Writing data
to the card is indicated with a progress bar graph displayed at the lower line of the LCD display. Do not remove the SD/SDHC card from
the transducer slot if writing to the card is in progress, because this
could lead to data corruption or device reset. Writing can be stopped
and the card can be removed once it is unmounted (section 5.3.2).
It is also possible, to force archive copy to the SD/SDHC
card or file system internal memory at any time by pressing the combination of
keys. If the transducer is in the variant
with the Ethernet interface, the archive data can be downloaded from
the file system memory via the FTP protocol using any FTP client
software.
Note: If the transducer is connected to the FTP client, then copying
the archive data from the internal memory to file system memory is
blocked! In order to acquire current data from the archive, disconnect
the FTP session and force archive copy (e.g. press
keys). After copying is finished connect again transducer with FTP client
software.
5.8.3. Archiving configuration
Registers 4064-4069 (table 37) and transducer menu
in
Settings → Archive group (table 7) are used for configuring archiving parameters. The archiving can be constant or conditional.
73
Triggering conditional archiving can be implemented using one of four
options presented in figure 25 (n-on, n-off, off, on). Continuous
archiving is switched on by selecting the archiving type h-on, and it is
switched off by selecting the option h-off.

configured according to the example from table 22
(Archiving “1” means that archiving is switched on).
5.8.4. Memory card or internal file system memory (option)
P30U transducers in P30U-X1XXXXXX manufacturing
variants support memory cards are compliant with SD and SDHC
standard. P30U transducers in P30U-X2XXXXXX manufacturing
variants are equipped with a internal file system memory – 8GB memory
capacity. FAT and FAT32 file systems are supported. If the memory
card is not formatted, it should be formatted in the card reader using
a PC. P30U transducer creates folders and files during operation,
containing archive data. Before inserting the card into the transducer,
check if the card write protection option is not switched on.
Do not remove the memory card from the transducer before it is un-
76
mount (see section 5.3.2.) – unmount the card by pressing the following
If a mounted card is removed, the corruption
keys:
of the data stored on the memory card can be damaged. The memory
card status is described in the transducer registers (sections 5.9.6,
table 46). Directly after the card is inserted, the card status will be
displayed for about 3 seconds on the display, as presented in the below
table:

An example number of records on an SD/SDHC card for 1 s archiving
period for a single archiving value is the following:
•
64MB card: approx. 1 900 000 records (about 22 days)
•
2 GB card: approx. 60 800 000 records (about. 700 days)
Note: It is recommended to use industrial grade
minimum class 6 SD/SDHC cards . Consumer grade
cards with class 6 write speed can also be used (please
note that consumer cards have operating temperature
range limited to 0...40°C).
77
During the operation, the P30U transducer creates folders
and files on the SD/SDHC memory card or in the internal file system
memory. An example folder structure is shown on fig. 27.
Fig.27. Folder structure on the memory card (internal file system)
Apart from the ARCH folder where recorded data are stored,
also the SYSTEM folder is created on the memory in which the start.txt
file is stored to save the date and hour of installation of the memory card
(also when starting the device after the power supply has been lost).
Data on the memory card or internal file system memory
are stored as files located in folders corresponding to the device name
and serial number – see fig. 27. File names correspond to the date
of recording and have the following format XXXX_YY.Dzz, where
XXXX → year , YY → month. Extension of files have following format:
Dzz, where „zz” is subsequent number of file from the same month.
For example, first archive file in May 2014 will have name: 2014_05.D00,
subsequent file: 2014_05.D01 etc. There can be created maximum 32
files for each month (*.D00 … *.D31). FIle number is changed automatically after reaching 12 MB file size if one or two values are recorded
Disp.Val or +2nd Val.
If transducer is configured for recording displayed value,
second displayed value and all queried values, the maximum file size is
calculated by transducer itself and depends on the number of queried
values.
78
5.8.5. Archive file structure
Files containing archive data on an external SD/SDHC
card or in the file system internal memory have a column structure,
where the subsequent data columns are separated from another
by a tab character. The first row contains the column header. Data
records are placed in order in rows, and the fields of a given record are
separated from one another with a tab character. The view of an example file has been shown in fig. 28.
Fig.28. Example data file
Subsequent fields contained in the row describing the record have
the following meaning:
•
date – date of data recording, “-” character is the date separator
•
time – hour, minute, second of data registration, “:” character
is the time separator
•
Disp.Value – recorded displayed value of the transducer, the decimal separator depends on the language version set in the transducer menu – “,” character is the separator in the Polish version;
“.” character is the separator for all other language versions; values
are provided in the engineering format
•
2-nd Disp.Val – recorded second displayed value of the transducer,
the decimal separator depends on the language version set
in the transducer menu – “,” character is the separator in the Polish
version; “.” character is the separator for all other language versions;
values are provided in the engineering format
•
R8000...R8049 – recorded registers from range 8000-8049 values querried by transducer with RS-485 interface configured
as Master or Monitor.
79
5.9. RS-485 Interface
The digital programmable P30U transducers are equipped
with a serial interface in the RS-485 standard to communicate in computer systems and with other Master devices. Asynchronous character
communication protocol MODBUS has been implemented on the serial
interface. The transmission protocol describes the methods of information exchange between devices via a serial interface.
5.9.1. Serial interface connection
RS-485 standard allows direct connection of up to 32
devices on a single serial link with the length of up to 1200 m
(with the baud rate 9600 b/s). In order to connect larger number of devices,
it is necessary to use additional intermediate-and-separating systems
such as PD51 made by LUMEL S.A. Connection diagram is presented
on the Fig. 3. In order to obtain correct transmission, it is necessary
to connect the lines A and B in parallel to their equivalents in other
devices. Connection should be made with a shielded cable.
The cable shield should be connected to the protective terminal as close
to the transducer as possible (the shield should be connected
to the protective terminal at one point only).
GND line is used for additional protection of the interface line
in case of long connections. In such a case, GND signals of all devices
on RS-485 bus should be connected.
To obtain a connection with a PC, an RS-485 interface card
or an appropriate converter, e.g. PD51 or PD10, is required. The method
of connecting devices has been shown on fig. 29.

5.9.2. MODBUS protocol description
The implemented protocol complies with Modicon’s PI-MBUS300 Rev G specification. P30U MODBUS protocol serial interface parameters :
•
Transducer address 1..247.
•
Transmission rate: 4800, 9600, 19200, 38400, 57600, 115200,
230400, 256000 [b/s].
•
Operation mode: RTU with the frame format: 8n2, 8e1, 8o1, 8n1.
•
Maximum time to start response: 200 ms (the response time may
get longer up to 500ms during saving the data to the SD/SDHC
card).
Serial interface configuration consists of setting the transmission rate, device address and the information unit format – protocol.
81
Note: Each transducer connected to the communication network must
have:
•
unique address, different from addresses of other devices connected to the network,
•
identical baud rate and type of information unit.

5.9.4. Register map
In the P30U transducer the data is stored in 16- and 32-bit
registers. The process variables and parameters of the device are
stored in the different address space depending on the variable type.
The bits in the 16-bit registers are numbered from the least significant
to the most significant (b0 … b15). The 32-bit registers (4 Bytes) contain
floating-point values in IEEE-754 standard. Bytes sequence: B3 B2 B1
B0 – the most significant byte is sent as the first one. 16-bit registers
which represents 32-bit values on a two following registers are multiplied
at different address field with different bytes (word) order: B1 B0 B3 B2
(table. 36).
Register map of the P30U transducer is shown in table 36.
Note: All the given addresses are physical addresses. In some
computer programs logical addressing is applied, then the addresses
should be increased by 1.

5.10. 10/100-BASE-T Ethernet interface
P30U transducers in P30U-X2XXXXXX manufacturing
variant are equipped with an Ethernet interface enabling connection
of the transducer (using RJ45 socket) to the local or global network
(LAN or WAN) and using network services implemented in the transducer: WWW server, FTP server, TCP/IP Modbus slave. To use
transducer’s network services, configure parameters in Ethernet transducer group. Standard transducer Ethernet parameters have been
shown in table 17. Transducer’s IP address is the basic parameter –
by default 192.168.1.30 – which must be unique within the network
that the device is being connected to. The IP Address can be assigned
to the transducer automatically by the DHCP server in the network,
if the address downloading via DHCP option is switched on: Ethernet
→ DHCP → On. If the DHCP service is switched off, the transducer
will operate with the default IP address enabling the user to change
the IP address e.g. via transducer menu. Each transducer Ethernet
parameter change requires accepting parameter changes, e.g. in menu
Ethernet → ReInitEt → Yes or by entering “1” in register 4099.
After accepting changes, the Ethernet interface will be reinitiated according to new parameters – all Ethernet interface services will be restarted.
5.10.1. Connecting 10/100-BASE-T Ethernet interface
To obtain access to Ethernet services, it is required to connect
the transducer to the network via RJ45 socket located in the front
section of the transducer, operating according to TCP/IP protocol.
Fig.30. View and pin order of transducer RJ45 socket
117
Description of transducer RJ45 socket LEDs:
•
yellow LED – switched on when the transducer is properly connected to the Ethernet 100 Base-T network, switched off when the transducer is not connected to the network or is connected to 10-Base-T
network
•
green LED – Tx/Rx, switched on when the transducer transmits
and receives data, flashes randomly, when no data is transmitted
it is constantly switched on
To connect the transducer to network, the following twisted pairs are
recommended:
•
U/FTP – each twisted pair foiled separately
•
F/FTP – each twisted pair foiled separately and additionally cable
foiled,
•
S/FTP (earlier SFTP) – each twisted pair foiled separately
and additionally cable braided,
•
SF/FTP (earlier S-STP) – each twisted pair foiled separately
and additionally cable foiled and braided,
Twisted pair according to European standard EN 50171,
at minimum: class D (category 5) – for fast local networks, includes
applications operating at up 100 MHz frequency bandwidth.
The connection description has been provided in table 44. Use category
5 STP (shielded) twisted pair cabling with RJ-45 connector with color
conductors (according to table 44) meeting the following standard:
•
•
118
EIA/TIA 568A for both connectors using the straight connection
of the P30U to the network hub or switch,
EIA/TIA 568A for the first connector and EIA/TIA 568B
for the second connector using the crossover connection, used,
among others, in the case of direct connection of the P30U transducer to the PC.

5.10.2. WWW server
The P30U transducer provides its own WWW server
enabling remote monitoring of measured values and remote configuration as well as reading the transducer status. In particular, the website
enables the following:
•
receiving information about the device (serial number, manufacturing variant code, firmware version, bootloader version, variant
(standard or special manufacturing variant),
•
viewing current measurement values
•
reading device status,
•
selecting website language.
To access the WWW server, user must enter the transducer’s
IP address in the internet browser, e.g.: http://192.168.1.30
(where 192.168.1.30 is the defined transducer’s address). Port “80”
is the standard WWW server port. The port server can be changed by
the user.
Note: The website requires a browser with JavaScript switched on that
is compatible with XHTML 1.0 (all leading browsers, Internet Explorer
version 8 and higher).

5.10.2.2. WWW user selection
The transducer has two user accounts for the WWW server
protected with individual passwords:
•
user: „admin”, password: „admin” - configuration and viewing
parameter access
•
user: „user”, password: „pass” - only viewing parameter access.
Writing
the
transducer’s
IP
address
in
the
browser,
e.g. http://192.168.1.30, will start display the log in window. User must
enter name and password.
120
Fig.32.
View of the transducer’s WWW server log in window
WWW server user names cannot be changed, but the user
passwords can be changed for every user. It is recommended to change the passwords for safety reasons. Password can be changed only
through the website in “Ethernet” parameters group. Passwords consist
of 8 characters maximum. If user will lose password and will not be able
to use the WWW server, default settings of the Ethernet interface should
be restored, e.g. using menu: Ethernet → EthStdPa → Yes
or enter “1” in register 4080. All default Ethernet interface parameters
(see table 17) and WWW server user passwords will be restored:
user „admin” → password: „admin” ;
user „user” → password „pass”.
After logging into the WWW server, a 5 minute session is opened. After 5 minutes, the user is automatically logged out of the WWW
server. Changing a parameter group renews the WWW session expiry
time.
121
5.10.3. FTP server
FTP protocol has been implemented in P30 transducers.
The transducer operates in a server FTP mode and enables clients
access to the transducer’s internal file system memory. Files can be
accessed by a PC, tablet with an installed FTP client software or with
another device operating in FTP client mode. Port “1025” – data port
and “21”– command port has been used for transmitting files via the FTP
protocol. The user can change the FTP protocol ports if it’s required.
Please note that the ports configuration of the server and client must
be identical.
The FTP client software can operate in passive or active mode. It is
recommended that passive mode should be selected, because in such
a case the connection is completely set up by the client (the client selects the data port). In active mode, the server selects the data port,
e.g. port “1025”. For transmitting files with the transducer, the maximum
of one simultaneous connection can be used, therefore the maximum
number of connections in the client program should be limited to “1”.
5.10.3.1. FTP user selection
The transducer has two user accounts for the FTP server
protected with individual passwords:
•
user: „admin”, password: „admin” - writing and reading file
access
•
user: „user”, password: „passftp” - only reading file access
FTP server user names cannot be changed, but the user
passwords can be changed for every user. It is recommended to change
the passwords for safety reasons. Password can be changed only
through the website in the “Ethernet” parameters group. Passwords
consist of 8 characters maximum. If user will lose password and will
not be able to use the FTP server, default settings
of the Ethernet interface should be restored, e.g. using menu:
Ethernet → EthStdPa → Yes or enter “1” in register 4080.
122
All default Ethernet interface parameters (see table 17) and FTP server
user passwords will be restored:
user „admin” → password: „admin” ;
user „user” → password „passftp”.
An internet browser is a basic FTP server client. Enter
the transducer’s IP address with “ftp” prefix. ftp://192.168.1.30
as a browser address and download archive files directly from the internet browser.
Fig.33. View of an FTP session opened in a browser window
123
5.10.4. TCP/IP Modbus
P30U transducers enable access to internal registers using
the Ethernet interface and TCP/IP Modbus Slave protocol. The functions
of Modbus protocol and structure of registers have been discussed
in section 5.9.3-5.9.6. It is required to set an unique IP address
for the transducer and to set connection parameters specified in table
45 to set up the connection.

is the device address for TCP/IP Modbus protocol and does not
correspond to the address value for RS-485 Modbus protocol
(Mbus 485 → Adres). If Adr mTCP transducer parameter is set
to “255”, the transducer will bypass the address analysis in the Modbus
protocol frame (broadcast mode).
