Hi new to the forums, but been reading for awhile now and hoping maybe someone knows what's happening as its puzzling me. I am currently trying to communicate with two QJ71E71-100 via crossover cable. I have my program communicating but I have two problems with receiving. Sending with an eight decimal value wrote to D10 produces the below on the receiving QJ71E71 D11000=10, D11001= 1, D11002= 2, D11003= 3, D11004= 4, D11005= 5, D11006= 1, D11007= 2, D11008= 3, D11009= 4, D11010= 5, .... Repeated upward Now if I increase my decimal value to 12 or upward on the Sending side, I get a strobe effected of data moving slowly upward in my D11000 registers If this isn't enough information I could attach my example program to see if someone could point out where I'm going wrong, I appropriate any help.

Thank you for your help I finally found the issue. By sending a single shot of data across the network with more than 16 words I saw that the data wasn't repeating or filling up the internal buffers which led to the conclusion that it works on a slower pace. After which I looked into the code and there was a loop in the sending that kept repeating the send signal continually thus filling up the buffers on the receiving end. I took the loop out and put it on a 1 second pulse for the time being and it works perfect. I can lower this down and configure the rest of the program and it should work wonderful. Thank you kaare_t, with your advice it gave me a direction which led to the problem. For anyone else who's looking at this problem, line 150 on the sending end take out the Set M1 on the first branch.

I have a COM ERR led on the receiving ethernet module that could be the cause, where do I locate the error page/log your talking about. *Edit* I found the modules detailed information under "Diagnostics > System Monitor > Detailed Information" and have the Error code C1B1 Which says a solution of execute the open processing. Thank you for your help and giving me a direction to move towards to solve this. I'll update the thread with how I get on.

I have cleared the D Registers before restarting both units and watched them populate as I have two programmers watching both the send and receive.

Please see attached The receive is currently repeating downward in the images attached no strobe currently with the value 10 in D10 D11 in the send and D11001 is a count these images were taken 2 minutes after each other.

I'm sorry misunderstanding on my part. I'm using two Q03UDECPU with two QJ71E71-100 talking to each other. In the attached file there are two projects one for the sending & one for receiving.

Hi, Thank you for your reply. Software: GX Developer Version 8.91V The cable is a regular Ethernet crossover cable Please see attached for the program I have been using. QJ71E71-100 Ethernet Module.zip
