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.
