AH500 Module Manual
16.1 Introduction to AHRTU-ETHN-5A
Thank you for choosing Delta AHRTU-ETHN-5A module. Please read the product instruction
carefully before use so as to install and operate the product properly.
AHRTU-ETHN-5A is AH series remote I/O module. AH series CPU such as AHCPU5x1-EN of V2.0
and above can easily control AH digital I/O module and analog I/O module through EtherNet/IP
communication protocol.
16.1.1 Function

Supports the standard EtherNet/IP communication protocol slave, I/O connection through
cyclic data exchange as well as explicit message connection through acyclic data exchange.

Provides module status (MS), network status (NS), I/O module status and a seven-segment
display showing AHRTU-ETHN-5A's status and error code.

Provides AHRTU error processing mechanism by setting how to process I/O modules and
AHCPU when an error occurs in I/O modules.

Able to connect 1 main backplane and 7 extension backplanes. Max. 68 AH series I/O
modules are connectable to AHRTU-ETHN-5A. Max. number of input and output points and
max. number of channels are 3744 and 544 respectively.
