3.3.2 Communication protocol

( 1 ) computers send to the controller:

1.The Nth-channel relay output      shut down instructions: O ( 00,N,0 ) E   open instructions : O ( 00,N,1 )E

Explain:

1)The 00 in the brackets are theaddress bitsofthecontroller, the address bit is 00 when it is only control one controller, and the same as follows.

2)The N value is 01~20;

3)For example: serial port control one controller of the first channel relay output.

Shut down instruction format is: O (00, 01, 0) E    Open instructions format is: O (00, 00, 1) E

2.All of the relay output fully on or off: the chief close(00,00,0)E the chief open(00,00,1)E;

3.Read the input point status: O(00,30,1)E    Command controller to return to the input data;

4.Read command format and function of the meaning of the output point status:

I(00,0000)E   command controller return to the first~ the tenth channel data;

5.Controller address setting: OA(00)E   the two numbers in the bracket for the controller address, Usually value range: 00~99, can also be special set more larger.

(2)\the controller send the input point status to the computer;

I(00,0000)E   The last four digits correspond to the status of four input points; 0 is for none input and 1 is for have input.

(3) the controller send the output point to the computer:

OA (00, 0000000000) E             the last ten digits correspond to the output status of the first channel to the tenth channel output point: 0 is for none output and 1is for have output.
