2.1 DESCRIPTION
Paperless recorder OMR 700
This recorder is intended for technologies and workings, where it is needed to display and/or record a number
of electrical and nonelectrical values at one place. Universality, versatility and
in particular good value for money predestine the recorder to fulfil most of your
demanding needs including the IP front panel cover.
Ourpaperlessrecorderhasbeendevelopedwithversatilityandintuitivecontrol
in mind. Thanks to its modularity the user can insert input or output cards into
any of the  existing slots. Maximal configuration of the recorder thus allows to
measure and record up to  inputs. In order to increase reliability, the recorder
has two systems - primary and backup.
Always on board are digital control iputs and outputs, serial line
RS , Ethernet /, USB connector as well as a  MB internal memory
to record the measured data.
Projection
Color 5,7“ TFT display with fine resolution dominates the device. The display is multi-touch and it there-
fore allows an ease of use.
Control
The recorder is controlled by both the touch screen and the push buttons with adjustable functions,
positioned underneath a sliding front door. Two LEDs indicate run/error and the state of data recording.
Setting
All functions and settings can be performed directly on the instrument´s display in a clear graphical menu.
Data recording
The OMR  can record measured data from any of its active inputs, nodes and mathematical functions.Data
are stored in the internal  MB memory with compression that allows up to four-fold increase in its physical
memory without slowing down. Data can also be stored on an external SD card or USB flash drive. In case of a
limited number of measuring inputs, measurement data can be stored with a period of up to  ms.
The records can be either in BIN or „CVS“ format. However, the latter is much more demanding on memory.

DESCRIPTION
OF THE INSTRUMENT
Modules
The development of the device has been performed with an increased emphasis on technical solutions and
universality. Card design not only allows their use in any position of the recorder, but also their additional
insertion into vacant slots. Thus, if new requirements to increase the number or Typee of inputs and outputs
occur in the course of using the recorder, just order yesther card and insert it into a vacant slot. In this way the
instrument can „grow“ in compliance with your requirements.
All analogue modules are fully isolated from the internal bus, and some cards have galvanic isolation even
between individual channels.
Basic version of the recorder includes power supply module and communication module with Ethernet /,
RS  (MODBUS), five digital inputs and two digital outputs.

CONNECTION
OF THE INSTRUMENT.
Supply lines of the instrument should not be situated in proximity of the incoming low-voltage signals.
Contactors,motorswithlargerinputpowerandotherpowerelements should not be situated close to the recorder.
Supply lines to the instrument input (measured quantity) should be situated at a sufficient distance from all
power lines and appliances. If this can not be secured, it is necessary to use shielded leads with connection
to the ground (terminal E).
The devices are tested according to the standards for use in industrial area, yet we recommend to abide by
the above principles.

BASIC BUILDING BLOCKS
OMR 700
Functionality of the paperless recorder OMR700 is based on the following parts
• Inputs and outputs
- come from the IO cards (fixed B or expanding A - A, B - B). They themselves contain conversions
• Nodes
- mathematical or other calculations with the goal of providing requested adjustments of the measured
signals or preparation of the output values
• Screens
- graphical representation of the measured or calculated values on the recorder display
• Records
- what, where, how often, in what format, and other parameters of measured or calculated data for recording
• Timers
- provide periodic execution of linked blocks with a given period
• Constants
- spontaneously unchangeable named values for calculations

SETTING
OF THE INSTRUMENT .
From the block chart it is apparent that the central point of the recorder is created by Nodes. They process the
measured inputs, constants, other nodes, and using the preset calculations they calculate a new value. The
calculation is kept in time by the timer. The calculated values of the nodes can be displayed on the screen and
recorded on the media. The outputs can also be equipped by them. An important feature of the nodes is the
fact that they can have a history (they remember previous values). This is an optional configuration offering the
advantage of displaying the value of the node with its history (running chart).
Timers have an optional setting period. The client can set the period within the Rangeof ms up to  days
(by ms, while the dialog limits the settings to the order of ms, s, minutes, hours, and days). There are N timers
in the recorder ( at the moment) so that it is necessary to choose a proper setting for each timer to cover
the needs of the entire recorder. The timers control calculations of the nodes and recording on the media,
while the internal mechanism guarantees that the nodes are calculated first and only then the new values are
recorded on the media.
Inputs and Outputs provide rate, which is different for each Typee of the card and even for each register on the
card. The IO cards are in fact designed as intelligent ones = they conduct their operations in order to relieve the
main processor. They are organized into a set of registers. Some of the registers are configurable (e.g. those of
input Range), some are designated for measured values under different phases of processing. A Typeical input
card provides several values for each input – direct input value of the converter (converter bits), value converted
into electrical value (e.g. mA), and the resulting converted value (e.g. in case of weight, the strain gauge input
card recalculates the voltage of the strain gauge into weight by a preset formula - Range, tare). Similarly, it is
possible to control also the outputs. For example: You set the requested turns of a ventilator and the card will
itself, according to the preset parameters, recalculate the measured value into voltage and set it on its output.
Constants are designated for easy and well-arRanged changes of the settings, e.g. of the required values,
filtration parameters... On one place the value can be changed, used for calculations, displayed and recorded.
Screens are used for displaying the measured values. There are N screens and each of them can occupy up
to M different elements like running chart, bar chart, nummber indicator, finger measuring indicator... You set
the element Typee, size, location, number of displayed values, color, Range... So you can build very diverse
screens. The redraw period is set in such a manner that it enables a smooth and fast enough drawing, which,
at the same time, relieves the main processor. Some elements (as e.g. the running chart) display, besides the
current values, also their previous ones. By these elements it is therefore advantageous if the displayed node
has a history that is used for filling up the chart when switching over to the screen.
Records serve for recording values on the media. To each record you can assign a name, frequency, file format,
number of records in the file, where you want to record, and, of course, what you want to record. All records
can be viewed in the record browser. They can also be downloaded to a PC and displayed there

State of the recorder
The recorder always operates in one of its four states (further details in the chapter Errors and warnings).
„OK“ - device has not detected any function problem
„Warning“ - device outside the specified values, but without consequences on its functioning.
This state can be caused for instance by an undervoltage greater than %, by filling the
memory in excess of %, and by many other causes. If the device returns within the specified
values, „Warning“ state will disappear and the log record will be carried out.
„Error“ - device outside the specified values, but with possible consequences onitsfunctioning.
This state can be caused for instance by an undervoltage greater than %, by filling the memory
in excess of %, and by many other causes. At the „Error“ state an error window is displayed,
through which you can view the errors. If the device returns within the specified values, „Error“
state will disappear and the logrecord will be carried out.
„Critical error“ - device outside the specified values with consequences on its functioning. This
state can be caused for instance by an undervoltage greater than % or by filling the memory
up to  % so that it is not possible to make records. At the „Critical error“ state an error window
is displayed, through which you can view the errors. If the device returns within the specified
values, both „Critical error“ and the error window remain displayed until a confirmation
(acknowledgment) of the „Critical error“ is done. After confirmation the log record will be carried
