2.1 About this Modbus pump
Metering pumps DULCO flex Control DFXa with a “Modbus RTU”
connector differ from standard pumps by way of the connection
option to a “Modbus RTU” bus system. A “Modbus RTU” pump
DULCO flex Control DFXa can either be connected to a “Modbus
RTU” bus or be used as a stand-alone unit.
Example:
n Measured value-dependent metering of sodium hypochlorite
into a swimming pool water circuit, where the pump is con‐
trolled by a PLC in
‘Modbus RTU’ operating mode.
A “Modbus RTU” version of the DULCO flex Control DFXa (identity
code feature “Control option” = M) is intended for integration into a
“Modbus RTU” system.
This document contains general information for the implementation
of the metering pump DULCO flex Control DFXa, DFXa into the
serial communication protocol of the Modbus RTU.
