● Introduction
● Features
5.4. USB I/O Expansion Unit
1. 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 USB-87Pn. After hot-swapping a module, all settings are
automatically loaded to recover.
2. Auto Confi guration
The I-87K I/O modules can be pre-confi gured and backed up in the non-volatile
memory of the RU-87Pn. When the USB-87Pn is power on or plugged in, the
USB-87Pn will automatically checks and restores these configurations to each
I-87K I/O modules on it.
3. Easy Diagnosis System
Using the DCON Utility, you can easily make a backup of the I-87K module
confi gurations and write to another USB-87Pn. This design can easily and quickly
duplicate many USB-87Pn.
4. Easy Maintenance and Diagnosis
There are several LED status indicators to show whether I-87K modules are confi gured 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 LED indicator design makes it easy for maintenance. There is no PC
and Notebook needed.
5. Communication
• USB network
The USB network connects the USB-87Pn to regular PC and notebook without any other media converter.
• DCON protocol
I-87K series I/O modules plugged in a USB-87Pn provides a simple command/response protocol (named DCON protocol) for communication.
All command/response are in easy use ASCII format.
The USB-87Pn series USB I/O expansion unit is designed to acquire and control
I/O through USB connections. It comprises
• A CPU module with none-volatile memory to backup/restore I/O module
confi gurations; LED indicators to diagnose the I/O module; and a USB port
for communication.
• A power module
• A backplane with a number of I/O slots for fl exible I/O confi guration.
With its patent-pending technologies, namely auto configuration and hot
swap, it saves lots of labor on the set up and maintenance of the automation
systems. 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 USB-87Pn. After hot-swapping a module, all settings are
automatically loaded to recover.
Furthermore, with the USB communication interface and more than 30 I/O
modules for choice, users can apply the unit to nearly any automation system.

6. 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 USB-87Pn is power on or plugged in, the
DO or AO modules output preconfigured Power On Value. When host watchdog is acted, DO or AO modules output preconfigured Safe Value.
• Wide range power input (10 ~ 30 V
DC
)
• Wide range operating temperature (-25°C ~ +75°C)
7. Fully Software Support
The free charge software utility and development kits include
• DCON Utility: for confi guration
• OPC Servers:
OPC is an industrial standard interface based on OLE technology. With the OPC server, I/O modules can be easily integrated to any software
that has OPC client capability.
8. EZ Data Logger
EZ Data Logger is a 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 a data logger software without any programming skill.
9. Various Software Develop Toolkits
DLL, ActiveX, Labview driver, Indusoft driver, DasyLab driver, Linux driver
