Hello!

I need to connect a PC to a modbus TCP network and retrieving data from modbus slave to a database or scada system. Can I do it though computers' network port with out using any extra hardware. Is there any software to access modbus TCP network directly through PC. Thanks in advance.

You will need software that can poll the slave and then server that data to an HMI, SCADA, or Historian package. KEPware's KEPServerEX V5 can do that. The Modbus Suite has a Modbus TCP/IP driver and can server data via OPC DA, OPC AE, OPC UA, OPC XI(coming in the sept. release), FastDDE/Suitelink (Wonderware), NIO (GE/Intellution), or simple DDE.

In addition there is a plugin for the server for doing basic data logging.

Yes, you can do this with no additional hardware. You will need software that understands Modbus, but it all just works with your normal Ethernet port.

Have you considered using OPC for this? It's a reliable and cost effective solution. Here is a link to the OPC Server for Modbus: http://is.gd/erKFG

If you are new to OPC, here are some tutorials that will bring you up to speed: http://is.gd/f0XVk

You could use Whzan, it has a free modbus gateway for the PC and an online mimic editor enabling you to dynamically view you data as process graphics from a browser. It also gives you history and alarms.
