7. RS 485 ( ModBus ) Output :

This supports MODBUS (RS485) RTU protocol( 2-wire ) .instrument

Connection should be made using twisted pair shielded cable. All "A" and "B" connections
are daisy chained together. The screens should also be connected to the “Gnd” terminal.
To avoid the possibility of loop currents, an Earth connection should be made at one point
on the network.Loop (ring) topology does not require any termination load. Line topology

may or may not require terminating loads depending on the type and length of cable used.

The impedance of the termination load should match the impedance of the cable and be at
bothends of the line. The cable should be terminated at each end with a 120 ohm
(1/4 Watt min.) resistor.

RS 485 network supports maximum length of 1.2km. Including the Master, a maximum of 32
instruments can be connected in Rs485 network.The permissible address range for the

is between 1 and 247 for 32 instruments. Broadcast Mode (address 0) is not allowed.instrument

The maximum latency time for the is 200ms i.e. this is the amount of time that instrument
can pass before the rst response character is output.

After sending any query through software ( of the Master) , it must allow 200ms of time to
elapse before assuming that the is not going to respond. If slave does not instrument
respond within 200 ms, Master can ignore the previous query and can issue fresh query
to the slave.

29

The each byte in RTU mode has following format:

8-bit binary, hexadecimal 0-9, A-F

2 hexadecimal characters contained in each 8-bit eld of
the message

4 bytes (32 bits) per parameter.

Floating point format ( to IEEE 754)
Most signicant byte rst (Alternative least signicant byte rst)

Format of Data Bytes

2 byte Cyclical Redundancy Check (CRC)

Error Checking Bytes

1 start bit,
8 data bits, least signicant bit sent rst
1 bit for even/odd parity
1 stop bit if parity is used; 1 or 2 bits if no parity

Byte format

Communication Baud Rate is user selectable from the front panel between 2400, 4800,
9600, 19200 bps.

Exception Cases : An exception code will be generated when the receives instrument
ModBus query with valid parity & error check but which contains some other error
( e.g. Attempt to set floating point variable to an invalid value ) The response generated
will be “Function code” Ored with HEX (80H ). The exception codes are listed below

Function code :

03

Read Holding Registers

Read content of read /write location ( 4X )

04

Read input Registers

Read content of read only location ( 3X )

16

Attempt to set a floating point variable to an invalid value

01

Illegal function

This function code is not supported by the instrument.

02

Illegal Data
Address

Attempt to access an invalid address or an attempt to read
or write part of a floating point value

Two consecutive 16 bit registers represent one parameter. Refer table 4 for the addresses
of 3X registers (Parameters measured by the instruments).
Each parameter is held in the 3X registers. Modbus Code 04 is used to access all parameters.

Example :

To read parameter ,
Volts 3 : Start address = 04 (Hex) Number of registers = 02

Note : Number of registers = Number of parameters x 2

Each Query for reading the data must be restricted to 20 parameters or less. Exceeding
the 20 parameter limit will cause a ModBus exception code to be returned.

Energy update rate is the time after which Energy registers are
updated. This time is user settable from 1 - 60 minutes

Word Order controls the order in which the receives instrument
or sends floating - point numbers:- normal or reversed register
order.In normal mode, the two registers that make up a floating
point numbers are sent most signicant bytes rst.
In reversed register mode , the two registers that make up
a floating point numbers are sent least signicant bytes rst.
To set the mode, write the value ‘2141.0’ into this register­the instrument will detect the order used to send this value and
set that order for all ModBus transaction involving floating point
numbers.

When the instrument displays Active power ( P )with “ + ” ( positive sign ) ,
the connection is “ Import ” .

When the instrument displays Active power ( P )with “ - ” ( negative sign ) ,
the connection is “ Export ” .

As the front of the enclosure conforms to IP54 it is protected from water spray from all directions,
additional protection to the panel may be obtained by the use of an optional panel gasket.

The terminals at the rear of the product should be protected from liquids.

The instrument should be mounted in a reasonably stable ambient
temperature and where the operating temperature is within the range

0

-10 to 55 C . Vibration should be kept to a minimum and the product should
not be mounted where it will be subjected to excessive direct sunlight.

9.1 EMC Installation Requirements

This product has been designed to meet the certication of the EU directives when installed to a
good code of practice for EMC in industrial environments, e.g.

1. Screened output and low signal input leads or have provision for tting RF suppression
components, such as ferrite absorbers, line lters etc., in the event that RF elds cause

problems.

Note: It is good practice to install sensitive electronic instruments that are performing critical
functions, in EMC enclosures that protect against electrical interference which could cause a
disturbance in function.

2. Avoid routing leads alongside cables and products that are, or could be, a source of

Caution

1. In the interest of safety and functionality this product must be installed by
a qualied engineer, abiding by any local regulations.

2. Voltages dangerous to human life are present at some of the terminal
connections of this unit. Ensure that all supplies are de-energised before
attempting any connection or disconnection.

3. These products do not have internal fuses therefore external fuses must
be used to ensure safety under fault conditions.

interference.

4. ESD precautions must be taken at all times when handling this product.

3. To protect the product against permanent damage, surge transients must be limited to
2kV pk. It is good EMC practice to suppress differential surges to 2kV at the source.
The unit has been designed to automatically recover in the event of a high level of
transients. In extreme circumstances it may be necessary to temporarily disconnect the
auxiliary supply for a period of greater than 5 seconds to restore correct operation.

The Current inputs of these products are designed for connection in to systems via
Current Transformers only, where one side is grounded.
