6 COMMUNICATIONS

The MEMORY MAP table shows the memory map addresses of each variable

that measures and calculates the analyzer and it’s code.

6.1 PERIPHERAL NUMBER AND BAUDRATE

It’s possible through a Modbus command to configure the device. The memory

locations that are changed are in the next table:

Modbus address Modified variable Valid range

3000, 3001 Device serial number 0 a 999999999

3002H Peripheral number 1 a 255

3002L Speed (baud rate) 0= 9600, 1= 19200

The Modbus command to send is (hex.):

Tx: 00100BB8000306NNNNNNNNPPVVCRC

Rx:

There is no answer in broadcast frame.

This command sets the peripherals number and the baud rate of communications

for devices connected in the same network that have the default peripheral

number. The command is sent to the peripheral number 0 (broadcast) to interpret

all devices, but only make the change the device that matches the serial number

is sent as parameter. The peripheral number and communications port speed be

set immediately, without requiring a reset of the device.

6.2 RS-485 LAYOUT

The picture shows how to connect a communication bus between multiple Power

Net. The converter can be RS-485 to RS-232 serial port or Ethernet depending

on the facility infrastructure. The standard RS-485 connection allows a maximum

of up to 32 peripherals in each bus.
