4.2  MODBUS COMMUNICATIONS

Applicable Flow Meter Models: 

ONICON F-1500 Series Turbine Flow Meters with Modbus 

communication protocol and firmware version 4.00.58 and above. 

Overview 

This document describes the preliminary implementation of the Modbus communication protocol 
for use in monitoring common process variables in the ONICON F-1500 Series Turbine Flow 
Meter. The physical layer utilizes the half-duplex RS-485 port and the Modbus protocol. 

 

Reference Documents 

The following documents are available online from www.modbus.org.

4.2.1 Wiring

An RS-485 daisy chained network configuration as depicted below is recommended.   
Do not use a star, ring, or cluster arrangement.

PIN LABELING (AMONG DEVICES)

“RS-485 –” = “A” = “TxD-/RxD-” = “Inverting pin”
“RS-485 +” = “B” = “TxD+/RxD+” = “Non-Inverting pin”
“RS-485 GND” = “GND” = “G” = “SC” = “Reference” 

! 

WARNING

Place controls in manual mode when making configuration changes to the vortex meter.

4.2.2  Menu Items 

The following menu items are in the Output Menu and allow selection and control of 
the Modbus communication protocol. 

Address

 

When the Modbus protocol is selected, the Modbus address is equal to the user's 

programmable device address if it is in the range 1…247 in accordance with the 
Modbus specification. If the device address is zero or is greater than 247, then the 
Modbus address is internally set to 1. 

Comm Protocol 

The Comm Protocol menu allows selection of “Modbus RTU Even,” “Modbus RTU 
Odd,” or “Modbus RTU None2,” or “Modbus RTU None1,” (non-standard Modbus) 
with Even, Odd and None referring to the parity selection. When even or odd parity is 
selected, the unit is configured for 8 data bits, 1 parity bit and 1 stop bit; with no parity,
