Title: Do-More Ethernet
Post by: JeffS on September 13, 2013, 10:10:35 AM

I have an application where I need to be able to send raw ASCII data to a specific port on a computer that is hooked into the same network as the Do-More PLC.  This communication was described to me as raw TCP.

Is this something that the Do-More can accomplish?

Thanks,

Jeff

Should work fine.

You'll need to create a TCPClient device in the System Configuration that specifies the TCP Port Number to use

look at the help topic for OPENTCP

if you need to receive data back from that TCP connection look at TCPLISTEN

...which is not to say that you would use the TCPLISTEN instruction to do so, you will use the STREAMIN, but I believe that information is covered in the help for TCPLISTEN.
