    The main purposed of this research paper was for implementation of APRS (Automatic Position Report System) Protocol in use with remote controller for controlling Exploration Vehicle where cannot be reached by the conventional wireless network. The research experiment expected result on success communicate between point to point distances over 10Km.

    This paper presents an approach to implementation for PLC used embedded application. We had created the designs base on structure model. The hardware are consist of 32-bits microcontroller (LPC2378), 4 Chanel analog I/O and 32 points digital I/O, and multi communication unit. The software considerable operating system on multitasking is called the real-time operating system (RTOS). This article discusses the scan time is very important for the PLC controller. It also shows how to calculating scan time then approach to run the user program. In the empirical study considered only the scan time operated by IL program, 20 commands. Which can be measuring respond time for appropriate the results equal to 152 μSec. while the PLC own calculation and run the program equal to 151 μSec. Both values are similar, different by 1 μSec. only © 2012 SICE.

    A design of the various control devices with a DMX512 Protocol is widely used in many areas, such as decorative lighting for both inside and outside of the building, or stage lighting and equipment control, such as spot light, smoke machine, strobe light, moving light. This article presents the creation of Embedded DMX512 Controller using FPGA with Real Time Operating System (RTOS). This creation enables us to build multiple channels of DMX Controller within a single device and to control DMX Controller through the TCP/IP. Thus we can control or update the data through the internet. © 2009 IEEE.
