COMMNICATION

Modbus Communications

KDAQSTATION supports the Modbus protocol (RTU master/slave), for easy installation on systems built using Modbus.

Modbus Master Function

The Modbus master function lets the CX unit read, display, and record digital data from slave devices.

Increase CX Inputs

A Modbus connection lets you input measurements and calculations from a DARWIN series* data acquisition unit as digital data to CX unit computation channels. This capability makes it possible to increase the number of CX unit inputs by simultaneously using DARWIN series measurement/computation channels.

*Communication module DT300-31/S6 is required. See the general specifications for DT300-31/S6 for further details.

Data Display/Record of Indicating Controller/Power Monitor

Data from Modbus-compatible devices can be input to CX unit computation channels as digital data for displaying and recording. For example, the CX unit can produce trend displays and save data such as power monitor cumulative power, indicator regulator SP, PV, and OUT.

In addition, data from these devices can be used by CX unit network functions and network applications.

For information on the operating requirements of individual Modbus slave devices, see the specifications for the particular slave device.

Modbus Slave Function

A master device can read CX unit register values. In addition, data written to the register by the host system can be displayed and recorded on the CX unit.
