1. Introduction
ET-87P2/4/8 series is a remote intelligent I/O expansion unit to expand I-87K series
I/O modules over the Ethernet for industrial monitoring and controlling applications. It
offers two Ethernet switch ports to form a daisy-chain topology. The daisy-chain
feature allows ET-87P2/4/8 to connect in series to each other or other Ethernet
devices. Users can easily simplify the cabling and save installation space with the
feature.
ET-87P2/4/8 is designed to be used in harsh and noisy environment, so the hardware
is manufactured with wide power input range (10~30 VDC), isolated power input and
can operate under wide temperature (-25 °C ~ +75 °C). To simplify installation and
maintenance of I/O modules, it provides many useful features, such as: hot swap
allowed, auto configuration, LED indicators for fault detection, dual watchdog to keep
alive, programmable power on and safe values for safety.
There are more than 30 I/O modules supported with the unit, including analog
input/output, digital input/output, counter, frequency I/O modules. We provide various
software development kits (SDK) and demos, such as DLL,ActiveX, Labview driver,
InduSoft driver, Linux driver, OPC server, etc. The I-87K series I/O modules plugged
in the ET-87P2/4/8 can be easily integrated into variant software system.

1.1. Features
Here is a summary of the key features which the ET-87Pn offers.
Hot Swap
Reliable 3-piece construction enables users to hot swap modules during
operation, without rewiring.All I/O module data are backed up in the non-volatile
memory of the ET-87n.After hot-swapping a module, all settings are
automatically loaded to recover.
Auto Configuration
The I-87K I/O modules can be pre-configured and backed up in the non-volatile
memory of the ET-87Pn. When the ET-87Pn is power on or plugged in, the
ET-87Pn will automatically checks and restores these configurations to each
I-87K I/O modules on it.

Multi-Host Access
Simultaneous access by a maximum of 6 host
PCs.
Although a maximum of 6 host PCs are allowed
simultaneous access, it is recommended that
fewer host PCs are used in order to give better
performance and stability.
Easy Duplicate System
Using the DON Utility, you can easily make a backup of the I-87K module
configurations and write to another ET-87Pn. This design can easily and quickly
duplicate many ET-87Pn.
Easy Maintenance and Diagnosis
The basic configurations (includes IP settings) are set by the push buttons and
7-segment LED display. The operator can easily set the ET-87Pn.And there are
several LED status indicators to show whether I-87K modules are configured and
work properly.
If one I-87K module fails, the operator just needs to replace it with one good
I-87K module with the same item number. And then checks the LED indicators to
know whether the replacement is performed correctly. The push buttons and LED
display design makes it easy for maintenance. There is no PC and Notebook
needed.

Various Software Develop Toolkits
DLL, ActiveX, Labview driver, Indusoft driver, DasyLab driver, Linux driver.
Fully Software Support
The free charge software utility and development kits include
●DCON Utility: for configuration
●OPC Servers:
OPC is an industrial standard
interface based on OLE
technology.
With the OPC server, I/O
modules can be easily build the
data logger software without
any programming skill.
EZ Data Logger
EZ Data Logger is the small data
logger software. It can be applied
to small remote I/O system. With
its user-friendly interface, users
can quickly and easily build the
data logger software without any
programming skill.

Communication
Daisy-Chain Ethernet topology
The ET-87Pn has a built-in two-port Ethernet switch to implement daisy-chain
topology. The cabling is much easier and total costs of cable and switch are
significantly reduced.
Tips & Warnings
In a daisy chain connection, each master can connect up to 10
ET-87Pn slaves simultaneously. If the number of ET-87Pn salve is
more than 10, it is recommended to increase a switch.

LAN Bypass Feature
LAN Bypass feature guarantees the
Ethernet communication. It will
automatically active to continue the
network traffic when ET-87Pn lost
its power.
DCON Protocol
I-87K series I/O modules plugged in a ET-87Pn provide a simple
command/response protocol (called DCON protocol) for communication.
All command/response are in easy used ASCII format.
Rugged Industrial Environment
●Dual Watchdog Design
The I-87K series I/O modules provides module watchdog and host watchdog.
The module watchdog is a hardware watchdog; the host watchdog is a software
watchdog. The module watchdog is designed to automatically reset the
microprocessor when the module hangs. The host watchdog monitors the host
controller (PC or PLC). The output of module can go to the safe value state when
the host fails.
●Programmable Power On Value & Safe Value
The DO and AO type I-87K I/O modules provide programmable Power On Value
& Safe Value. When ET-87Pn is power on or plugged in, The DO orAO modules
output preconfigured Power On Value. When host watchdog is acted, DO orAO
modules output preconfigured Safe Vale.
●Wide Range Power Input (10 ~ 30 VDC)
●Wide Range Operating Temperature (-25 ~ +75 °C)
