Example of Serial Port DIP switch setting

8

1 2 3 4 5 6 7

ON

[ White square indicates position of switch lever ]

Switches 1-5 = ID

This is set as a binary number with Switch 1 the least significant bit, and Switch
5 the Most significant bit.

In this example an address of 2 is selected.

Switch 6 reserved

.

(always leave switched off)

Switch 7 Default Conet/s (19200 baud) Protocol Select

.

Switch on to set Conet/s default mode of operation

In this example this switch is shown OFF.

Switch 8: Default Modbus ASCII (9600 baud) Protocol Selection

Switch 8 ON = Modbus ASCII slave at 9600 baud
(Data bits: 7;Parity: none; Stop bits: 1)

Switch 8 OFF = Internal protocol configuration
In this example, the Switch 8 is shown in the ON position to set the serial port to
its default configuration of MODBUS Slave Ascii at 9600.baud.

Set as shown, (switches 2 and 7 on) the serial port will operate as a Modbus ASCII
slave port at 9600 baud, and will respond to the slave address of 2.

Modbus Data Register Mapping

A facility of the Modbus Protocol provides the ability to map the Modbus
Data types (such as coils and holding Registers) to specific areas of the
CPU’s DIT. See the DIT Layout (see section 5.1) and the dvx Template file
help for more details.

4.5.1.4.

Modbus Compressed DIT Addressing

An additional feature provided for the Modbus Protocol is “Compressed DIT
addressing”.
The standard layout of the Data Interchange Table provides 4000 registers
for each Module Slot on a Maxiflex base (see section 5.1).
Some  Modbus  Master  devices  are  pre-programmed  with  a  maximum
allowable  range  of  10,000  holding  registers.  This  makes  it  impossible  to
access  the  DIT  registers  in  I/O  slots  from  Slot  3  onwards  (DIT  addresses
12,000 upwards).
This  feature  allows  the  user  to  select  a  smaller  number  of  registers  for
access  from  Modbus  in  each  slot,  allowing  the  Modbus  holding  register
addressing  to  be  compressed  to  fit  into  the  10,000  holding  register  limit
imposed.
The  CPU  slot  must  always  be  allocated  4000  registers,  and  so  the  I/O
module  in  Slot  1  must  start  at  address  4000.  If  the  start  address  for  this
