Metering pumps DULCO flex Control DFXa with a "Modbus RTU"
connection differ from standard pumps by way of the option to con-
nect 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:
Measured value-dependent metering of sodium-calcium hypo-
n
chlorite into a swimming pool water circuit, where the pump is
controlled by a PLC in
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.
