1.1 Features
Ethernet –based Data Acquisition I/O unit
The i-8430,i-8830,i-8KE4 and i-8KE8 are Ethernet I/O unit. This feature allows Ethernet
applications to access and control the remote I/O in industrial filed network. And
E10M_nnn.exe or 8KE10.exe is the DCON firmware for the i-8430, i-8830, i-8KE4 and
i-8KE8. Using this firmware, applications can be easily and directly developed using a
TCP program, or via VxComm technology.
ASCII-based protocol (DCON Protocol)
The i-8430,i-8830,i-8KE4 and i-8KE8 Ethernet I/O units use the DCON protocol, which
is a request/reply communication protocol used with I-7000/8000/87K series I/O
modules. And is used to access the data from the module using a simple ASCII format.
For example, sending the command “$01M” will query the controller name. The
responding module will reply with a message similar to “!018KE4(cr)” or “!018430(cr)”
For more details regarding the DCON Protocol,
please refer to Appendix B: DCON protocol.
For DCON Protocol about 8000 MCU and 8000 series I/O modules. Please refer to :

I/O configurable via the Ethernet
The DCON Utility is used to configure I-7000, I-8000 and I-87K series I/O modules. It
originally communicated with the I/O modules via the COM port. For I/O modules on the
i-8430,i-8830,i-8KE4 and i-8KE8, using the VxComm technique to create a virtual COM
port can let DCON Utility access the I/O modules via the Ethernet. For more details,
please refer to Chapter 3.
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.

Dual Bus design to supports i-8K and i-87K series I/O modules
The 8430/8830/8KE4/8KE8 has two types of bus on its back plane. The first is a serial
bus (RS-485 interface) for 87K I/O modules and the second is a parallel bus for 8K I/O
modules. The DCON firmware can support both 8K and 87K series I/O modules. These
two series I/O modules can both be connected into the same I-8000 MCU, and can use
the same DCON command when they are both attached to I-8000 MCU. The modules
for DI, DO, DIO, AI, AO and Counter/Frequency purpose are supported. Other modules,
such as multi-serial port (8112, 8144, 8142, 8144), MMC (8073), motion (8090, 8091),
are not supported. For more details, please refer to Appendix D: i-8K and i-87K series
I/O modules.
For more about I/O module’s information, please refer to
CD:\ Napdos\DCON\IO_Module\hw_dcon_on_8KUnit

More flexible I/O combination and Compact、fasten、quick to install
The 8430/8830/8KE4/8KE8 Ethernet I/O units contain either a 4-slot or 8-slot bus to
allow various i/o modules to be connected, removing the need for complex wiring
between i/o modules. Furthermore, various I/O modules can be inserted into the slots at
the same time, such as digital input/output, analog input/output and counter modules,
and each I/O module allows various numbers of channels. For example, with i-8040 or
i-8041, the 8830/8KE8 provides max 256 digital input or digital output channels.The
module can simply be plugged into the slot and secured to the plastic base using a pair
of locking buttons. The assembly can then be mounted on the control box using DIN rail
clips.

Built-in Watchdog
The built-in watchdog circuit will reset the CPU module if a failure occurs in either the
hardware or software. If the application program does not refresh the watchdog timer
within 0.8 sec, the watchdog circuit will initiate a reset of the CPU.
Input Protection circuitry
The protection circuitry on both the network and power supply protects the system from
external signals such as main spikes and ambient electrical noise. In addition, the
central processing module is isolated from external signals in three ways. This is
achieved through I/O isolation of 3KV, power isolation to 3KV and network isolation to
2KV
High performance integrated power supply
The built-in isolated 20W power supply is rated to perform linearly up to full loading.
Ventilated housing design to work between -25 ~+75℃

4.7.1 Introduction
OPC (OLE for Process Control) is the first standard resulting from the collaboration of a
number of leading worldwide automation suppliers working in cooperation with Microsoft.
Originally based on Microsoft's OLE COM (component object model) and DCOM
(distributed component object model) technologies, the specification defined a standard set
of objects, interfaces and methods for use in process control and manufacturing automation
applications to facilitate interoperability. The COM/DCOM technologies provided the
framework for software products to be developed. There are now hundreds of OPC Data
Access servers and clients.

z Ethernet: I-8000E MCU with E10M_nnn.exe (or 8KE10.exe) firmware
Speed: 10Mbps
Even though the I-7000/87K series I/O modules are not equipped with an Ethernet interface,
by using the I-7188E/8000E in connection with the VxComm technique, they can still be
accessed via the Ethernet.
Note:
1. I-8000 MCU includes 8410, 8411, 8810, 8811, 8430,8431, 8830, 8831, 8KE4, 8KE8.
2. 8000E means an I-8000 MCU equipped with an Ethernet port, such as 8430, 8431,
8830, 8831, 8KE4, 8KE8.
3. Both the I-8000 and I-87K series I/O modules can be inserted into the I-8000 MCU
simultaneously.
4. When the I-87K series I/O module is inserted into the I-8000 MCU, it uses the same
commands as the I-8000 series I/O modules .
5. The 87K series expansion unit series includes 87K4, 87K5, 87K8, 87K9.
6. The I-87K series I/O modules use different commands when they are inserted into the
I-8000 MCU and the I-87K expansion unit.

Appendix C: VxComm technique
VxComm (“Virtual Communication Port”) is a technique that allows access to remote I/O
slots or RS-232 ports. There are two types of software interfaces that can be used to
access remote I/O modules and the COM ports of the 7188E/8000E series the first is serial
port interface and the second is the TCP/IP interface. For the serial port interface, we
provide a VxComm driver for Windows OS. It is used to create virtual COM ports to map to
I/O modules and COM ports of the 7188E and 8000E. After creating virtual COM ports, you
can easily upgrade serial devices to with Ethernet communication ability and the original
software only need to link to a virtual COM port. It doesn’t need any source code
modification.

Appendix D: i-8K and i-87K series I/O modules
The DCON firmware (DCON_nnn.exe and E10M_nnn.exe) supports both 8K and 87K
series I/O modules. The two series I/O modules can be plug in same I-8000 MCU. The
modules for DI, DO, DIO, AI, AO and Counter/Frequency purpose are supported. Other
modules such as multi-serial port (8112, 8144, 8142, 8144), MMC(8073), motion (8090,
8091) are not supported. The file in the shipped CD lists details.
CD:\Napdos\Driver\DCON_Utility\DCON_Utility_Module_List.htm
The DCON firmware only accepts 4 digits numbers. Thus both 8K and 87K series are
recognized as 4 digits numbers. When using the DCON Utility to search I/O modules, the
screen shown as following:

The differences between I-8000 and I-87K series I/O modules are
Item i-8000 series i-87K series
Microprocessor No Yes (8051)
Communication interface Parallel bus (Note1) Serial bus (Note2)
Communication speed Fast Slow
DI latched function No Yes
Counter input (for digital input module) No Yes (100 Hz)
Power on value Yes (Note3) Yes
Safe value Yes (Note3) Yes
Host watchdog Yes Yes
Module watchdog No Yes
Programmable slew-rate for AO module No Yes
Note:
1. The 8000 series and 87K I/O modules can both be connected into the same i-8000
MCU, for there are two types of buses on i-8000 series main-board. Through the
parallel bus, the CPU can communicate with I/O modules very fast. For digital I/O
modules, the communication time takes less than 0.012 ms. For analog I/O modules, it
depends on the modules. For example, I-8017H’s scan rate is 50K samples per
second and I-8024’s throughput is 2100 samples per second.
2. Through the serial bus (RS-485), the communication speed is 115200 bps Maximum.
The communication time depends on the command and response length (bytes).
Normally, for digital I/O modules, one module takes less then 1 ms; for analog I/O
modules, one sample takes less than 2 ms.
3. The hardware design of the I-8000 series I/O modules doesn’t have the power on
value and safe value. Running the DCON firmware on the I-8000 MCU, they can have
the functions.
