Overview
1-1 Features
In this manual, the DeviceNet-compatible K3HB Digital Indicator is abbrevi-
ated as K3HB-DRT.
1-1-1 Outline
The K3HB-DRT Digital Indicators are slaves that connect to the DeviceNet
open field network. DeviceNet communications enable controlling operation,
collecting measurement data, and writing settings from a host computer or
PLC. The K3HB-DRT support both remote I/O communications and explicit
message communications.
Remote I/O communications allow the master and the K3HB-DRT to automat-
ically share data via high-speed I/O without any special programming of the
master. Remote I/O communications are particularly suited to operation con-
trol, error warnings, and monitoring applications.
Explicit messages use a communications protocol for sending commands and
receiving responses. The main application for explicit message communica-
tions is for changing K3HB-DRT settings data.
