Introduction Of Ahrtu-Dnet-5A; Feature; Function And Specifications - Delta AH500 Manual

11.1 Introduction of AHRTU-DNET-5A

1. Thank you for choosing Delta AHRTU-DNET-5A. To ensure correct installation and operation of
the device, please read the instruction carefully before use.
2. This manual only provides introductory information on AH10PFBS-5A. Detailed information
about DeviceNet protocol is not included in this manual. Please refer to relevant literatures for
more information on DeviceNet protocol.
3. Defined as a remote I/O module for data exchange, AHRTU-DNET-5A is used for connecting
AH500 series I/O module, analog I/O module, temperature module and AH10SCM-5A module
to the DeviceNet network.

11.1.1 Feature


It supports the standard DeviceNet communication protocol as the DeviceNet slave.

It supports explicit connection via predefined Master/Slave connection set.

It supports polling.

The network configuration software DeviceNet Builder provides the graphic configuration
interface, automatically scans and identifies I/O modules, randomly maps the parameters of
special modules as I/O exchange data, sets the methods to deal with the errors and diagnoses
the error status of each module.

According to the actual need, users select whether to retain the buffer register information when
the network is offline.

It is can be connected to one main rack, 7 extension racks and 68 AH500 series I/O modules.
The maximum input and output data it supports: 980 bytes respectively

It supports a hot swap. (When power ON, the device can be plugged directly for use after being
removed.)
