The answer is yes, but what are you trying to do?

Are you messaging strings between PLCs or are you trying to create your own data packet to communicate to an ethernet device such as a bar code printer ?

Yes, I need to send an string to a PC, but the family of PLCs is S7-200, sorry, but my question again is, is this posible.
