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 : CD:\Napdos\DCON\IO_Module\hw_dcon_on_8KUnit ftp://ftp.icpdas.com/pub/cd/8000cd/napdos/dcon/io_module/hw_dcon_on_8kunit/

Various SDK provided (free)

In order to access the I/O modules that are connected to 8430/8830/8KE4/8KE8. Various SDKs are provided, such as: (see Note1, Note2, Note3)

zDLL driver

zActiveX component

zLabView bundled driver

zIndusoft bundled driver

zLinux driver

zOPC server

Note1: All these SDKs include the DCON Command and can be easily and quickly integrated into the user's system. Please refer to Chapter 3 for more detail information.

Note2: When applied to an Ethernet interface, users should first install VxComm utility when using these SDKs

Note3: DLL, ActiveX, LabView, IndoSoft, OPC server and VxComm utility only support the windows platform. (Windows 98, Windows NT, Windows 2000, Windows XP)
