Introduction

Modbus  is  a  serial  communication  protocol  commonly  used  in  industrial  applications.  It 

allows communications between many devices and is typically used to transmit data from 

instruments or control devices back to a main controller or data gathering system. 
The  Modbus  implementation  for  the  RIM10  Series  allows  the  user  to  view  and  modify 

flowmeter  parameters. Appendix A lists the available Modbus registers.  Modbus uses a 

Master / Slave  communication  scheme.  The  RIM10  is  always  the  Modbus  slave.  The 

customer must provide the Modbus Master.

Supported Modbus Protocols 

The RIM10 supports two types of Modus communications.

- 

Modbus TCP / IP.  

- 

Modbus RS-485.  (RTU)

Configuration  

Configuration of the RIM10 consists of software set-up and physical wiring. 

1.   Software  set-up: 

Using  the  LCD  or  Web  interface,  select  'Network  Set-up',  'Modbus 

Network'. Select 'TCP' for Ethernet or 'RTU' for RS-485. Be sure to save when done. 

See  Appendix  B  for  web  page  screen  shots.  The  LCD  or  Web  page  interface 

documentation provides details on flowmeter operation.

Note: 

Always  power-cycle  the  flowmeter  after  making  any  changes  to  the  Modbus 

configuration.

2.   Physical Wiring: 

TCP / IP requires connecting an Ethernet cable from the flowmeter to  

a PC / Controller. RS-485 requires wiring from the terminal block of the flowmeter to a 

PC / Controller.  Only  a  2  wire  configuration  is  supported  for  RS-485.  A  termination 

jumper is provided if the unit is the last device. See wiring diagram section for details.

Read operation

The RIM10 flowmeter only supports Modbus register reads. 
The following operations are required to perform a read / write operation using Modbus:

1.

   Connect to the flowmeter using a Modbus master program.

2.

   Select a register from the Modbus register list.

3.

   Read/write the register from the master.  

Note: 

Reading or writing a Modbus register 

typically requires specifying the number of bytes.   See appendix A for register map.

4.

  The Modbus data packets are transferred as 2, 16-bit words, low word / high word, low 

byte / high byte.  The Modbus master program must ensure that the 2 bytes that form 

the 16-bit words are ordered as high byte / low byte.
