3 GENERAL PRODUCT OVERVIEW
3.1 Purpose
DL7 / DL7L is a multi-channel microprocessor-based measuring device with
electronically recorded measurement results. The device is intended to measure process
signals in industrial applications and may be used to measure physical values processed
into a standard current loop signal 0-20mA or 4-20mA, e.g. temperature, humidity, pressure,
flow, level and chemical composition, etc. The device is perfectly suited for slow rate variable
runs with changes at a few seconds intervals. Process values recording and flexible I/O
configuration, makes the data logger suitable for monitoring parameters in warehouse
settings or in the supervision of production lines. The device has math channels that enable
selected mathematical operations on the measured values, according to the formulas
entered by the user. The user configurable display and browse functions makes the device
suitable for use as a paper-less electronic logger. The device may be connected to a PC or
plant control system via Ethernet or RS-485 communication ports.
Each device is provided with a basic module and can be extended with an additional I/O
modules. Details are provided in section AVAILABLE I/O MODULES.
The device is supplied with 24 VDC source. Detailed information concerning the power
supply is given in consecutive parts of the document, in section Power connection.
3.2 Basic functions
100 programmable channels
The device enables setting up to 100 freely programmable channels. For each of them
the current, the maximum and the minimum value of the channel is displayed.
Measurement of the process values
Depending on the needs, the device may be provided with up to 42 measurement
inputs/outputs. The read values can be assigned to channels and archived.
Remote reading transmitter in the HART protocol
If seven 1HRT modules are installed, then the device enables remote reading of up to
100 values in the HART protocol. For one module, up to 25 values can be read. It is possible
to read the variables PV, TV, SV, FV and DVC. The read values can be assigned to channels
and archived.
Remote reading transmitter with digital output Modbus RTU
If four 2RS485(24V) or seven 2RS485 modules are installed, then the device enables
remote reading of up to 100 values (Modbus RTU protocol). For one module, up to 25 values
can be read. The read values can be assigned to channels and archived.
Remote reading transmitter with digital output Modbus TCP (Client)
The device enables remote reading of up to 100 values from 20 devices (Modbus TCP
protocol). The read values can be assigned to channels and archived.
Flow measurement
Each measurement input (including binary inputs) and each calculated value have two
independent totalizers assigned. Totalizers for pulse inputs can provide precise pulses
count. Message containing totalizers values can be sent automatically in the form of an

DL7, DL7L
12
e-mail (up to 5 recipients) at the indicated hour every day, on a selected day of the week or
on a selected day of the month.
Alarms and control
Two alarm thresholds may be set for every channel. Binary outputs can be assigned to
alarm thresholds. Two modes are available for alarms: latched (‘Alarm’ mode) and
non-latched (‘Control’ mode). The binary output module (OUT6RL) contains 6 outputs
relays. The message about exceeding the alarm threshold and return to the normal value
can be sent automatically in the form of an e-mail (up to 5 recipients).
Math channels
Within the math channels, selected mathematical operations are available: addition,
subtraction, division, multiplication, raising to the 2, 3 or any power and square root. The
formula entered in the math channel can contain up to 200 characters.
Results recording
Process values, math channels and totalizers can be recorded into internal flash memory
with the capacity of 2 GB. Data are saved as text files and protected with encoded
checksum. Apart from the measured values, the recorder also saves events (power loss,
resetting, exceeded threshold values, etc.) and authorised operations.
Displaying the results
Measured and calculated results can be displayed on the 7” colour LCD screen.
Depending on the configuration, results are displayed as graphs or digits (max. 11 signs
displayed for process values and max. 14 signs displayed for totalizers; after exceeding the
measuring range for process value or totalizer value, the ----- symbol will be displayed on
the screen and will be saved in the archive). The results can be also displayed collectively
as trend charts or tables (max. 11 signs for process values and totalizers values).
Measurement screens can be browsed sequentially or set to a selected channel.
Communication with a supervisory computer or a control system
The recorder enable data transmission to a supervisory computer or a control system by
means of:
a built-in RS-485 serial port; available Modbus RTU protocol,
Ethernet port; available Modbus TCP protocol.
3.3 Software for PC
Additional dedicated software can be downloaded from the Manufacturer's website:
www.metronic.pl.
Software for device configuration
DL7 / DL7L - dedicated software (DL7 Config.exe) enables device configuration through
the use of the computer. The software is intuitive and has an interface which is very similar
to the interface of the device. The software can be installed on the computers with the MS
Win operating system. Additional information in section DL7 Config.
Software for archived data visualization and analysis
The REPORT software (DL7-RP.exe) for archived data enables visualization and
analysis, using the computer. The DL7-RPplus.exe program enables online transfer of
archived data. Additional information in section DL7-RP (DL7-RPplus).

From April 1, 2020, the PSBATT module is manufactured only in version 1.2. Version
1.2 of the module is not backward compatible. The Operating Manual contains
information on connecting and configuring the module only in version 1.2. Technical
details about the module in version 1.0 and in version 1.1 are available from the
Manufacturer. Version 1.0 and 1.1 of the module is not visible in the Hardware
configuration in the Information about the device window (the "-------" sign and the red
color of the bar is displayed) and in the I/O settings window (the "------- " sign is
displayed).
CAUTION
If module IN6I(24V) or 2RS485(24V) installed and operating as a power supply source
for external devices, ambient temperature is limited to 0 .. +40 °C. In all other configurations
the ambient temperature range is 0 .. +50 °C.

5 MECHANICAL INSTALLATION
!
Prior to the commencement of any assembly work, read carefully the
information concerning safety described in section SAFETY INFORMATION.
5.1 Mechanical installation of DL7 device
DL7 is a panel-mounted device. It can be mounted into panels at least 1 mm thick.
Before installation, a 186(+1.1) mm X 138(+1) mm rectangular opening must be cut out in the
panel. The mounting depth of the device (with connected terminals) is 97 mm. In order to
ensure easy installation of electrical connections, it is recommended to leave an extra space
of approx. 30 mm behind the device.
When installing the recorder in the panel opening, the seal between the housing frame
and the panel have to be fitted. After inserting the recorder into panel opening, the fixing
clamps should be latched on both side walls and then tighten the screws.With the removable
screw terminal block, one can first install electrical connections and then fit the recorder.
