NUFLO CamCor Coriolis Flowmeters Modbus Protocol

The communications protocol for CamCor CT Series and PRO Series is in accordance with Modicon, Inc. RTU Mode Modbus as described in Modicon Modbus Protocol Reference Guide, PI-MBUS-300 Rev. J, June 1996. All registers are implemented as 4X or holding registers. Reading of registers is implemented via Function Code (03H) (Read Holding Registers). Writing to registers is implemented via Function Code 16 (10H) (Preset Multiple Registers).

CamCor’s Modbus communications allow host devices (PC, sequencer, etc.) to connect to slave devices via RS-485 connection. Modbus communication is based on the Master-Slave system, where host devices are designated as “master” and the Coriolis meter(s) is designated as “slave.” The system is Modbus-protocol compliant.

A CamCor meter purchased with the Modbus Communication option is shipped with the baud rate set to 9600. The baud rate is adjustable using the SW3-1 and SW3-2 switches on the maintenance board located in the transmitter body.
