ductors (IGBT) including a digital micro-controller.
Our equipment complies with IEC EN 62040-2 standard.
CAUTION : “This is a product for restricted sales distribution to informed partners. Installation restrictions or addi-
tional measures may be needed to prevent disturbances”.
SOCOMEC UPS reserves the right to modify their specifications at any time as far as this con-
tributes to technical progress.
SAVETY REQUIREMNENT
Using conditions:
Do read carefully these operation instructions before using the JBUS/MODBUS interface.
Whatever the repairs, they must be made only by authorised staffs, which have been suitably trained. It is recom-
mended that the ambient temperature and humidity of the UPS environment are maintained below the values
specified by the manufacturer.
UPS operating reference
Respect the safety requirements.
Do read carefully the operation instructions of DELPHYS MX / MP.
For an optimal operation, it is recommended to maintain the ambient temperature and humidity of the UPS envi-
ronment below the values specified by the manufacturer.
This equipment meets the requirements of the European directives applied to this product. As a consequence it is
labelled as follows:
ENVIRONMENT
Recycling of electrical products and equipment.
Provision is made in European countries to break up and recycle materials making up the system. The various components
must be disposed of in accordance with the legal provisions in force in the country where the system is installed.

INTRODUCTION
General purpose
This document provides required information of the J JB BU US S/ /M MO OD DB BU US S protocol serial link.
Before connecting a supervision equipment or BMS system (Building management system) to the UPS, it is
necessary to install and set up the serial interface.
This interface is located in the DELPHYS MX / MP « com-slot », and should be set through the control
panel or via the graphic touch screen (optional).
DELPHYS MX / MP is able to manage up to 2 independent J JB BU US S/ /M MO OD DB BU US S serial links.
JBUS/MODBUS protocol
This document does not explain the J
JB BU US S/ /M MO OD DB BU US S protocol management. Please refer on
www.modbus.org web site for more information.
The DELPHYS MX / MP J JB BU US S/ /M MO OD DB BU US S uses the following functions :
- function 3 for reading Input Registers (16 bits),
- function 6 for writing single Registers (to control UPS).
The data field is composed of words, defined by a MSB (most significant byte) and a LSB (lowest
significant byte), and displayed in the following order on the serial link.
1 WORD DATA
b7MSB b0b7LSB b0
b15 b0
Data decoding
Status and alarms Information
This information are coding in bit. This means that 1 word defines 16 information. If the related bit is set to
1, this information is active or true.
Measurements and counters data
1 word defines a measurement or a counter. Some values are numeric decimal signed or unsigned (0 to
65535 or from -32767 to 32767), or in hexadecimal (0x0000 to 0xFFFF).
Compatibility with other SOCOMEC UPS products
In order to be fully compatible with other SOCOMEC UPSproducts such as MASTERYS, DELPHYS DS
and DELPHYS DS elite, DELPHYS MX / MP proposes the same J JB BU US S/ /M MO OD DB BU US S tables.

JBUS/MODBUS SERIAL INTERFACE INSTALLATION INSIDE DELPHYS MX / MP
‘Com-Slots’ localisation
The « Com-Slots » integrates all communication interfaces, and it is located at the bottom of the UPS, on
the right side.
Slots 5 and 6 are dedicated to J JB BU US S/ /M MO OD DB BU US S serial interfaces.
Slots 1 to 4 are used for the alarm report boards, 3 inputs and 4 programmable relays (ADC).
JBUS/MODBUS serial interface plug in
The serial interface should be plugged in the corresponding slot, and fixed with 2 crews.
DELPHYS MX / MP is able to manage up to 2 independent J JB BU US S/ /M MO OD DB BU US S interfaces. Each interface can
be set differently, like the slave numbers.
JBUS interface in parallel system configuration
There is only one J JB BU US S/ /M MO OD DB BU US S serial link interface for a parallel system configuration. One serial
interface is used for the whole installation. The access to the data of the UPS module or unit is
managed by the table addressing1.

Connections and cablings
NOTE : there is only one connection per interface (RS232 or RS422 or RS485)
9 RS232 connection
)Standard PC connection
)Sub-D 9 pins connector
)Pin 2 : Rx
)Pin 3 : Tx
)Pin 5 : GND
9 Isolated RS485 connection
)2 wires connection
)« dip-switch c» allows connecting the terminal resistor
)Isolation via “opto-coupler”
)2 polarization resistors could be removed easily (if needed).

JBUS/MODBUS Protocol
Reminder:
The J JB BU US S/ /M MO OD DB BU US S protocol available on DELPHYS MX / MP is slave and in RTU mode.
It uses the function 3 as ‘read registers’ and the function 6 as ‘write register’.
The slave number is set via the control panel or via the graphic touch screen.
Conventions
The table addresses are written in hexadecimal, beginning with ‘0x’.
Some PLC systems request a relative address starting from 400 (0x0190) or 40001 (0x9C41), on this
address it’s necessary to add the first address of the J JB BU US S/ /M MO OD DB BU US S table.
Frame errors management:
In case of wrong data request, the UPS answers with the following frame error :
Error function code Error code Cause
80 + code function 1 Function error
80 + code function 2 Addresses error
80 + code function 3 Wrong data
80 + code function 6 busy

JBUS/MODBUS TABLES IN PARALLEL SYSTEM CONFIGURATION
Reminder
In UPS parallel system configuration, there is only one J JB BU US S/ /M MO OD DB BU US S interface. The addresses mapping
gives the possibility to read data from each module and common bypass. There is no link between the
J
JB BU US S/ /M MO OD DB BU US S salve number and the UPS unit or module one.
The interface is plugged in the ‘com-slots’ of the common cabinet is case of central bypass installation or in
the UPS unit 1 “com slots” in case of modular system (see bellow).
How to read data:
The identifications, status and alarms tables should be read completely in one JBUS/MODBUS frame; this
means the number of word to read is equal to the table length.
The measurements table could be read word by word, without exceed the length of the table. (from 0x1060
to 0x108F).
Incoming data structure:

JB BU US S/ /M MO OD DB BU US S link setting
The setting of the link is made from the control panel or from the graphic touch screen of the common
cabinet or of the UPS unit 1.

Preliminary remarks
The following J JB BU US S/ /M MO OD DB BU US S addresses tables only indicate the LSB byte, the MSB depends of the
module number requested.
An ‘X’ in the ‘CC’ (central bypass), ‘Module’ or ‘Unit’ column means that this information is available on
this equipment.
Please refer to § 4.4 for more details.
