7. MID COMPLIANCE
The following points must be taken into consideration to ensure that the device is used in compliance with directive
MID 2004/22/EC:
• Type of network
The DIRISA14 meter complies with the MID directive for connection to networks: 4NBL and 3NBL using
3CTs (see "6.2. Connecting to the electrical network and to loads", page 10)
• Fitting terminal covers (see g.1)
After connecting the product, ensure that the terminal covers are tted properly and secured by the two
plastic seals provided with the product.
• Locking the programming button
Close the button cap by securing it with a seal (see g.2)
• RS485 communication
The information provided via the RS485 COM is transmitted for information only and has no legal value.
• Declaration of MID conformity
The MID declaration of conformity is available on the website: www.socomec.fr

DIRIS A14 - 542957A - SOCOMEC
8. COMMUNICATION
8.1. Overview
The modbus available on the DIRISA14 communicates via an RS485 series link (2 or 3 wires) which is used to
operate products from a PC or an API.
In a standard conguration an RS485 connection is used to connect 32 products to a PC or a controller over 1200
metres.

Repeater
8.2. RS485 rules
A LIYCY shielded twisted pair must be used. We recommend using a shielded twisted pair with a general LIYCY-CY
shielding in an environment where there is interference or in a very long network with a number of products.
If the distance of 1200 m is exceeded and/or the number of products is greater than 32, a repeater must be added
to enable additional products to be connected.
A 120 Ohm resistor must be xed at both ends of the connection.

14 EN DIRIS A14 - 542957A - SOCOMEC
8.3. Communication structure
The product communicates via a modbus protocol which involves a dialogue in accordance with a master/slave
structure. The communication mode is the RTU (Remote Terminal Unit) mode with hexadecimal characters composed
of at least 8 bits.
Modbus frame structure (master -> slave question):
Slave address Function code Address Number of words to be
read
CRC 16
1 byte 1 byte 2 bytes 2 bytes 2 bytes
To comply with the modbus protocol, the inter-character time must be ≤ 3 silences.
This means the time for 3 characters to be emitted so that the message is processed by the DIRISA14.
In order to use the information correctly, you must use the modbus functions in accordance with the codes:
• 3: to read n words (maximum 128).
• 6: to write one word.
• 16: to write n words (maximum 128).
N.B.:
1 word <=> 2 bytes <=> 16 bits
2 words <=> 4 bytes <=> 32 bits
By selecting the slave address 0, a message is transmitted to all the devices on the network (only for functions 6
and 16).
Note: The response time (question/ response time out) is no more than 250 ms.
8.4. Communication tables
The communication tables and the associated explanations are
available on the DIRIS A14 documentation page on the website at
the following address:
www.socomec.com/en/diris-a14

9. CONFIGURATION
The device can be congured by the Easy Cong conguration software or directly from the DIRIS A 14 screen using
the programming mode. The paragraphs below describe conguring using the screen.
9.1. Conguring using the screen
On the screen, the programming mode is used to modify parameters, such as the type of network, current transformers
or communication parameters. How to browse through the programming mode is described in the following stages:
Go to programming mode
(using a screwdriver, press PROG for 3 seconds)
0,5 mm
3 mm
Go to the next menu
(press PROG once)
Modifies the current screen parameters
Validates the modification
Exit programming mode
(press PROG for 3 seconds)
Note: after 120 seconds of inactivity, the device exits programming mode without saving the changes (except for a
reset).

16 EN DIRIS A14 - 542957A - SOCOMEC
9.1.1. Example: conguring the choice of current transformer
In programming mode (see page 15), go to the "Current Transformer - CT" screen.
Example: changing the transformation ratio to 800/5.
