Hi, I'm wondering if you can help me with this problem.
I need to pull out from my DL06 PLC some registers once a day and I don't know if I need to purchase an ethernet module or I can do it with the programing port.
I found a modbus-TCP/IP module that can communicate via ethernet but I need some kind of control to establish the communication, the DDE, I think so.

I also have an eztouch panel connected to the plc, so, maybe I could access thru there.
The issue is that I need it to be not too much expensive

I hope you can help me, I will appreciate that.

If you want cheap and are only collecting a handful of values then:

You can use the programming port with an rs232 cable, then communicate using the dde-server and something like excel or a vb program, etc. I also think one of the serial ports can communicate using modbus RTU, but i can't remember check the manual.


Otherwise if you want speed and/or have the PLC on a plant network then an ECOM module would be nice. You can use Modbus TCP with that, or the opc server, or the dde server, or something like Dataworx.

The easiest way to do that is over Modbus RTU to one of the two serial ports on the DL06. You can do that with SeeThru for $50, at www.tractrola.com
