Ok, I can not way to try the driver.... next week I tell you if it works in the factory... :) Thanks a lot.

Ok good. Next week i can try in a factory. Therefore I have to send first this packet: byte[] pacchetto = new byte[20]; int errore = 0; pacchetto[0] = 70; //header -> FINSpacchetto[1] = 73;pacchetto[2] = 78;pacchetto[3] = 83;pacchetto[4] = 0; //length = 12 bytespacchetto[5] = 0;pacchetto[6] = 0;pacchetto[7] = 12;pacchetto[8] = 0; //command = 0pacchetto[9] = 0;pacchetto[10] = 0;pacchetto[11] = 0;pacchetto[12] = 0; //error code = 0pacchetto[13] = 0;pacchetto[14] = 0;pacchetto[15] = 0;pacchetto[16] = 0; //client node address automatically obtained when it is set to 0pacchetto[17] = 0;pacchetto[18] = 0;pacchetto[19] = 0; Get response of PLC that return me the client node address. after this I can send this command: byte[] pacchetto = new byte[34]; pacchetto[0] = 70; //header -> FINSpacchetto[1] = 73;pacchetto[2] = 78;pacchetto[3] = 83;pacchetto[4] = 0; //length after commandpacchetto[5] = 0;pacchetto[6] = 0;pacchetto[7] = 22;pacchetto[8] = 0; //command = 2pacchetto[9] = 0;pacchetto[10] = 0;pacchetto[11] = 2;pacchetto[12] = 0; //error code = 0pacchetto[13] = 0;pacchetto[14] = 0;pacchetto[15] = 0;//fins framepacchetto[16] = -128; //icf pacchetto[17] = 0; //rsvpacchetto[18] = 2; //gctpacchetto[19] = 0; //dnapacchetto[20] = 0; //da1pacchetto[21] = 0; //da2 pacchetto[22] = 0; //snapacchetto[23] = clientNode; //sa1pacchetto[24] = 0; //sa2pacchetto[25] = 100; //sidpacchetto[26] = 1; //mrcpacchetto[27] = 1; //srcpacchetto[28] = -126; //tipo di memoria 82 -> DMpacchetto[29] = 0; //word iniziopacchetto[30] = -116; pacchetto[31] = 0; //bit iniziopacchetto[32] = 0;pacchetto[33] = 32; //quante word And then read the response that it will contain the value of word.

Mmmm...I have to change the packet that i send? I think that i have to send: header - length - cmd - errCode- node 70 73 78 83 0 0 0 12 0 0 0 2 0 0 0 0 0 0 0 80 Response PLC: header - length - cmd - errCode- node - server node 70 73 78 83 0 0 0 12 0 0 0 2 0 0 0 0 0 0 0 80 0 0 0 0 Now i can send the complete command like this: node 70 73 78 83 0 0 0 26 0 0 0 2 0 0 0 0 -128 0 2 0 0 0 0 -13 0 100 1 1 -126 0 -116 0 0 32 -> read word from word 140 to 172. Right ?

I have done a test in a factory. This is the packet that I send to PLC: 70 73 78 83 0 0 0 26 0 0 0 2 0 0 0 0 -128 0 2 0 0 0 0 -13 0 100 1 1 -126 0 -116 0 0 32 -> read word from word 140 to 172. This is the response of PLC: 70, 73, 78, 83, 0, 0, 0, 16, 0, 0, 0, 1, 0, 0, 0, 2, -128, 0, 2, 0, 0, 0, 0, 80 Can someone help me please? Thanks.

I don't know if it's ok... I hope that you can tell me if it is ok or not... tomorrow or Friday I have to do a test in a factory...

I want to understand the logic of protocol. Can i send directly FINS READ COMMAND after inizializated socket to plc ? Or i have to send SEND FINS/TCP COMMAND after that SEND FINS COMMAND FRAME to read the words ? Thanks.

I don't understand. I want to have a program that simulated PLC Omron with FINS protocol and then i can use my program written in Java to communicate with the simulator. There is a guide to follow for configure PeakHMI ? Thanks.

Hi guys! There is a way to try this code? Thanks. I have to do the same thing; communicate to omron fins protocol by tcp/ip in java. Before read this post I used DataInputStream,DataOutpurSterean with ByteArrayOuputStream and ByteArrayInputStream with normal socket not datagramsocket. It use correct to use datagramsocket? Help me.. Thanks.

Thanks..

Thanks, it works fine. I'm new in this kind of progrmmation. I want to know something about FINS protocol: In follow your code and create a my project and it is subdivided in: OmronFinsPacket.java that is a class than help me to create tcp_header (byte array - size = 16) ,fins_header (byte array - size = 10) and fins_cmd (byte array - size = 8)OmronFins.java that is the main class that contain some method ( connect,close, writeOmronFinsPacket, readOmronFinsPacket etc ) . In the main I create OmronFins object , call the method and write it into a serverSocket that it receive the OmronFinsPacket and re-send it to the client for control if i write correctly. But now I want to understand how can I test my program? And if i can use an emulator of PLC when i write to PLC OmronFinsPacket, what is the response of PLC ? Thanks.

Good post!
