SMART GRID STATION CONTROL OVER WEB CHAPTER: 10: TESTING METHODOLOGIESCHAPTER: 10: TESTING METHODOLOGY

10.0OVERVIEW:

This chapter summing up all the work done of the two circuits designed; poles sensors circuit interface to the PLC system and Ethernet control system. Both the circuits depend on each other in such manner that one circuit is the poles sensing section and load control system stands for PLC and second is Ethernet control system. Hence practically it is now going to be implemented together.

10.3STATUS SIGNAL INTERFACE:

This interface comprises of microcontroller and opto-coupler as the input signals are coming from the temperature and humidity control section interfaced with this interface microcontroller. Then after that the input signal then process and corresponding status signal of 4 bit generates by the microcontroller to be fed to the PLC system to manipulate further.

TABLE: 18: STATUS SIGNAL DESCRIPTION

10.3.1 Explain:

For this interface the routine is as like having 6 different inputs from the temperature and humidity control system. Hence those control signals simply appears over the interface input and generates the signals.

10.3.2 Software Routine:

ALGORITHM

Having 6 inputs and for each input the output code is defined from 0000 to 0110
