PC send data to PLC

2 posts in this topic

Hello, i'm newbie for plc.

i want to ask about PC/computer send data to PLC CP1E with serial communication (RS232).

my wiring cable is:

PC                         PLC

2                             2

3                             3

5                             9

4&6   

7&8

                              4&5

and if i send data from PC to PLC, my indicator in COMM is blinking. i think the cable have no problem.

but if i send data from PC to PLC, the memory is not same as what i send and whatever i send data, the memory didn't change.

i will attach my ladder diagram.

what should i do?

First of all, the reception completed flag is A392.06.  Secondly, post a picture of the settings for the comm port.  Or just go ahead and post your project (.cxp file).
