nandgate Posts: 319 Rating: (9)	Hello All, I have an application in which 2 PCs have to communicate with each other through wireless communication. For that i am using Access Point W786 and Client point W746 (The main PC (Server) is connected to W786 and the client PC is connected to W746).There is no PLC involved. How can i establish communication between the 2 PCs by means of these two wireless devices ? is there any OPC Server available or should i switch to Socket program ? Kindly suggest With regards, nand gate.

nandgate Posts: 319 Rating: (9)	Hello Amit, I have already read that FAQ. I am able to configure both the Access and Client point (assign IP address, SSID etc). But i want transfer data from one PC to another using these 2 devices. How can i do it? With regards, nand gate.

Hello Nandgate, Access point & Client Devices will be provide you only wireless connectivity & it will not play any role in communication of data from One PC to another PC. Are you able to ping IP address of both PC i.e Are you able to access both PC remotely? By the way what kind of data communication you are looking for?

nandgate Posts: 319 Rating: (9)	Hello Amit, I am able to ping one PC from another PC. So i think that the communication is established. My actual requirement is something like this. My client PC is mounted on a moving crane, which inturn is connected to W746 (through a ethernet cable). The server PC is connected to W786 (through a ethernet cable). As said earlier the wireless link is already established between the two. The client PC has to send a string value to the Server PC. The Server will send an acknowledgement to Client and will save the string data in a database. I have written code for all the other aspects except for communication between PCs. Is there any OPC sever available for this communication ? If it is not avaiable then i should switch over to socket programming, (something i want to avoid cause it is time consuming). Kindly let me know if any OPC server is available for this, or any simpler form of communication. Thanks and regards, nand gate.

Rated X Posts: 1547 Rating: (129)	Hello nandgate, You can use OPC server for this communication, but it is strange to do it this way. I suggest using socket communication. You will find many samples on internet to realize this. Depending on your programming language you use. In general you have to open a socket. One station has to establishthe connection to the other station and then you can send or receive at the same over this one connection. Very easy to use and regular shown in all sample programs. Here you will find a sample from Microsoft. http://msdn.microsoft.com/en-us/library/bew39x2a.aspx

nandgate Posts: 319 Rating: (9)	Hello Rated X, Thanks for the reply and link. I am familiar with Socket programming. But i was actually hoping for some OPC based communication example. OPC based application will reduce my application size. Thanks and regards, nand gate.

Rated X Posts: 1547 Rating: (129)	Hi, OPC is much more complex as socket programming. No Object structure andsimple events. My last link was to MSDN if you have a look to a real sample with only the required features it is only some code lines.
