APAX-5070 User Manual 2
1.1 Introduction
APAX-5070 module is a compact Modbus/TCP coupler. Modbus/TCP protocol is very
popular in industrial automation applications. APAX-5070 can recognize connected
APAX-5000 I/O modules, and perform as a communication interface between those I/
O modules and remote devices by Modbus/TCP protocol.
In other words, APAX-5070 is Modbus/TCP server, offering APAX-5000 I/O modules'
data to remote Modbus/TCP client device like PC, PLC or controllers.
There are maximum 32 APAX-5000 I/O modules which can be recognized by one
APAX-5070 coupler module. All APAX-5000 I/O modules' input and output data will
be allocated to the Modbus address, and user can choose default assignment or
manually assigned through Advantech APAX utility or user's programs. Then user's
application programs or HMI software, which supports Modbus/TCP protocol, can
monitor and control these APAX-5000 I/O modules remotely. Refer to APAX-5070
Software Manual for how to assign I/O data to Modbus address in APAX utility.
1.2 System Architecture
APAX-5070 needs to be inserted on APAX-5002 backplane to get power. By assem-
bling with other APAX-5000 I/O modules on APAX-5002 backplanes, APAX-5070 can
communicate with other APAX-5000 I/O modules through the backplanes. Refer to
Section 3.1 for the assembly operation.
APAX-5070 is equipped with 2 RJ-45 LAN ports, sharing the same IP address with a
built-in Ethernet switch. This makes APAX-5070 able to build a line or star topology.
Using line topology, It can significantly save system wiring and cabling cost in many
industrial automation applications. Refer to figure below.
Figure 1.1 Line Topology for APAX-5070
Note! When you use line topology, if one APAX-5070 loses power, the con-
nection to the following APAX-5070 will be disconnected. If you want to
prevent from it, you can choose star topology.

Chapter 1 Overview
Figure 1.2 Star Topology for APAX-5070
The default IP address is 10.0.0.1. User can change the IP address by APAX utility or
.NET class libraries. The maximum distance between two APAX-5070 is 100 m.
Because APAX-5070 leverages standard Ethernet switch, theoretically there won't be
limitation for the number of APAX-5070 cascaded in line topology (the response time
of the farthest module will be longer when the number of APAX-5070 increases),
making the line length as long as possible.
Warning! DO NOT connect the two LAN ports on one APAX-5070 to the same
Ethernet switch as shown above. The communication won't work.
Note! You can reset the IP address back to default value by the jumper
located on CN29.

1.3 Features
1.3.1 Ethernet Ports
The APAX-5070 is equipped with two Ethernet ports with the same IP address (a
built-in Ethernet switch connects to these two ports) which is fully compliant with
IEEE 802.3u 10/100Mbpst. The Ethernet ports provide standard RJ-45 connectors
with an upper left LED indicator on the front side showing Link/Activity (Off: Not Link,
Green and Flash: Link and Activity), and lower left LED indicator showing LAN speed
(Orange: 100 Mbps, Off: 10 Mbps). Refer to figure below for Ethernet port pin
assignment.
1.3.2 Watchdog Timer
The built-in watchdog timer is designed to automatically reset the microprocessor if
the system fails. This feature greatly reduces the level of maintenance required and
makes the APAX-5070 ideal for use in applications which require a high level of sys-
tem stability.
1.3.3 Security
Though Ethernet technology comes with great benefits in speed and integration,
there also exists risks about network invasion from outside. For this reason, a secu-
rity protection design was built into the APAX-5070. Once the user has set the pass-
word into APAX-5070, important system configurations (network, firmware,
password, etc.) can only be changed through password verification.
