GOOD PRACTICES AND SAFETY INSTRUCTIONS
Safety recommendations
If the device is supplied with 100 / 240 V AC, it is mandatory to connect it to the ground with a good
link to the ground, to protect against electric hazard or electrocution.
It is dangerous to change the status of the outputs.
They can control power actuators or other equipment (mechanical, pneumatic, hydraulic, electrical or
other) which can cause serious personal injury and damage to surrounding material.
For safety and quality measurement reasons, it is important, before powering on the device, to ensure
that it is air supplied with a minimum operating pressure (0.6 MPa ± 15%).
Recommendations for the test environment
Keep the test area as clean as possible.
Recommendations for operators
ATEQ recommends that the operators who use the devices have training and a level of qualification
that correspond to the job to perform.
General recommendations
—
Read the user manual before using the device.
—
All electrical connections to the device must be equipped with safety systems (fuses, circuit
breakers, etc.) adapted to the needs and in accordance with the applicable standards and rules.
—
To avoid electromagnetic interference, electrical connections to the device must be shorter than 2
meters.
—
Power supply plug must be grounded.
—
Disconnect the device from the mains before performing any maintenance work.
—
Shut off the compressed air supply when working on the pneumatic assembly.
—
Do not open a connected device.
—
Avoid splashing water on the device.
ATEQ is at your disposal for any information concerning the use of the device under maximum safety
conditions.
We draw your attention to the fact that ATEQ cannot be held responsible for any accident related to
a misuse of the measuring instrument, the workstation or non-compliance of the installation with
safety rules.
In addition, ATEQ declines any responsibility for the calibration or the fitting of their instruments that
is not done by ATEQ.
ATEQ also declines any responsibility for any modification (program, mechanical or electrical) of the
device done without their written consent.

Preamble
INTRODUCTION
This manual intends to help you for the configuration and the use of your ATEQ F6 device on the
Modbus RTU network.
For more information on your ATEQ equipment, refer to the Quick Start Manual.

BASIC NOTIONS
The numerical values used in the ATEQ device are coded on a Long format.
ATEQ devices are configured in Little Endian format. It means that the Least Significant Byte is sent
first on the network.
Word
A word is a 16-bit data. It is coded with two bytes (8bits):
—
The first byte is the Least Significant Byte ( LSB )
—
The second byte is the Most Significant Byte ( MSB )
Example of a word:
Reminder: “h” indicates a hexadecimal code, “(d)” indicates a decimal code.
Long format (Signed Double word)
A Long format data is coded with two words (of 16 bits).
In the memory range of the ATEQ device or when they are transmitted, both words are coming in the
following order:
—
The first word is the least significant word
—
The second word is the most significant word
—
Example of a Long format:
Address value
All address values are treated with the Long format.
Example –address of the “millibar” unit in the Unit table (see Unit table):
FG_F6_MODBUS_EN_01 / 2020-06-17
6 / 74
Numerical value
All the numerical values are treated with the Long format with fixed comma (10-3).
Thus, their value is expressed in thousandths of unit. So, this value must be multiplied by 1000 to get
the value in units.
For example, a value of 207055 represents 207.055. So, any numerical value must be divided by 1000
to get the real value:
—
207.055 = 207055 ÷ 1000
Example –Pressure:
Negative numerical value
All the negative numerical values are treated with Signed long format with fixed comma (10-3).
Thus, they must be multiplied by 1000 to get the value in units.
Example –Leak value (signed long):

Hardware installation
HARDWARE CONFIGURATION
Connect your ATEQ equipment to the Modbus RTU network using its Modbus RTU connectors and
compatible cables.
Your device has one Modbus RTU connector.
For more information on your ATEQ equipment, refer to the Quick Start Manual.

Architecture of the Modbus RTU network
The network is built on the basis of a cable composed of two pairs of entwined and shielded wires.
One pair is for the signals and the other is for the ground.

Configuration of the ATEQ device
(slave)
Use this procedure to configure your device.
This configuration can be done with the front panel of your ATEQ device
The Modbus RTU configuration on an ATEQ device is always 8 bits long with one stop bit.
SETUP OF THE RS232 MODE
From the ATEQ device
From the MAIN MENU screen of your
ATEQ device:
➢CONFIGURATION
➢AUTOMATISM
➢RS232
Choose MODBUS value in the new
window.
It will also give you access to the serial
parameters.

SETUP OF THE STATION NUMBER
The station number must be the same on slave and master.
From the ATEQ device
From the MAIN MENU screen of your
ATEQ device:
➢CONFIGURATION
➢AUTOMATISM
➢RS232: MODBUS
➢ADDRESS
The station number can be equal to a value between 1 and 255.
