6. Communication MODBUS®
6.1. General Information
The MODBUS®communication bus is available on DIRIS A17
It is achieved via an RS485 serial link (2 or 3 wires) for using products from a PC or an API.
a distance of 1200 meters.

Repeater

0 -> NC
6.2. Recommendations
It is necessary to use a shielded twisted pair (LIYCY type). In a disturbed environnement or large network (in terms
of length) we recommend the use of a shielded twisted pair (type LIYCY-CY).
A repeater should be used if the distance of 1200 m and/or maximum number of 32 products are exceeded.
6.3. Communication structure
The MODBUS®used by the product involves a dialogue using a master-slave structure. The mode of communication
is the RTU (Remote Terminal Unit) using hexadecimal characters of at least 8 bits.
Structure of the MODBUS®sequence (question master -> slave):
Slave address Function code Address Number of words to be
read
CRC 16
1 byte 1 byte 2 bytes 2 bytes 2 bytes
8DIRIS A17 - Ref.: 541 984 A
According to the MODBUS®protocol, transmission time must be less than 3 silences,
i.e. the emission time of 3 characters so that the message is processed by the DIRIS A17.
To use this information correctly, it is necessary to use the MODBUS®functions according to the codes:
3: to read n words (maximum 128).
6: to write one word.
16: to write n words (maximum 128).
Note:
1 word<=> 2 octets <=> 16 bits
2 word<=> 4 octets <=> 32 bits
When selecting the slave address 0, a message is sent to all the devices present on the network (only for functions
6 and 16).
Note: The response time (time out question/answer) is 250 ms.
6.4. Register table
The communication tables and associated explanations are
available in the documentations page of DIRIS A17 on internet web
site at the following address:

7. Programming
DIRIS A17 display.
Refer to following paragraphs for programming from the display.
7.1. Navigation principle
The programming mode allows to modify parameters such as network type, integration time, input/output, alarms
or communication parameters. The process to navigate indide the programming mode is described in the following
steps:
Open programming mode
(pressing PROG button dor 3 sec)
Enter the code (factory default code is: 100).
For modifying the parameters displayed
Case of a value
to be modified Case of a digital value to be set
Change the value Change first digit
Select next digit to changed
Change first digit
Validate modification

7.2. Access to programming mode
By pressing "E/PROG" button for 3 seconds, device will enter the programming mode. Default code is: 100.
