Hi! I have a Siemens S7-300 and I need to establish a connection to a pc using labview and the respective opc server. However, I can not do it. The plc does not switch off the "stop" light and the "run" light does not stop blinking. The "BATF" anf "SF" lights are always on. Using the opc server, should the connection be established automaticaly or do I need any kind of plc related software? Thanks.

Following the working I have been doing, I have encountered another problem. I am using CJ1M from Omron and the I will use CPU 315 2DP (siemens) and connect them to Labview using ethernet. However, I tried to use Hyperterminal (or telnet) to test it. Pressing any key, the response becomes always the same: FINS za<$ Between "FINS" and "za" are three [] (squares). Does anyone know what this means? Does anyone know how to establish the connection I need? Can the Siemens plc establish a connection with labview? How? With an OPC server? Thanks.

Thanks. I am going to gather the info I need and try OPC. I suppouse OPC works with Siemens as well, right?

I need the ethernet because the work I am doing is to be implemented in a industrial company and they use this system. I was told about OPC but I do not know how it works. What is it for? Labview does not support cx-p or FINS?

The problem is that I do not know how to config labview or to write the Labview protocol.

The CPU I am using is CJ1M CPU12-ETN from Omron. Today I have established the communication between this CPU and the cx-programmer. My problem lies in the labview part. I have been trying but I cannot establish a proper communication. What I need is the program to make it work. After this I will have establish the same connection using the Siemens' CPU I mentioned.

I am working with the cJ1w-pa202 plc from Omron but then I will have to make the communication using 315 2DP from Siemens.

Labview works with these plcs, and I have to establish the communication with it. However, it is a bit difficult and I have stopped my work because of this problem.

Hi! Thanks for your reply. I need help making the program that allows the connection between the plc (Siemans, Omron) and labview by ethernet or the actual thing already made. It is really important and urgent. I have established the connection using RS232 but using labview is another thing. Thank you.

Hi! I need to establish a communication between a plc and labview using ethernet. I have developed the same communication using RS232, but not with ethernet. Does anyone have the code I need? Can anyone help me, please? Thank you.
