Hi there,
I have a problem that should be simple, but I'm wracking my brains as to why it's not working.
I have some TCP comms set up to send data from a cRIO to my PC - I have previously had it working in my office, with the same PC and cRIO, but now I have moved the system to the customer site and the loops are not connecting and I can't work out why.
I have stripped the VIs down to simplify what I'm doing and attached them here. Interestingly, I have another set of TCP loops working to send data in the other direction - from the PC to the cRIO and that one seems to be working. I have managed to get this loop working by removing the IP address and addressing them locally on the PC, and I managed to get that working as well, but when I try to connect to the RIO, it's like the loops go out of sync, the TCP listen is getting a new connection ID, even though the PC loop is in the middle of trying to send data.
I think that there must be some sort of setting or config issue, as the code has previously worked. Another thing I have noticed, is that when running the TCP I keep getting the message 'Target is not responding', which I haven't gotten before now. My other TCP loop is also getting this message once, when I first establish the connection, but as this loop keeps disconnecting, I keep losing connection to the RIO every few seconds. Again, I did not notice we getting these connection drops before on either loops and I am now getting it on both when establishing the connection. I've checked the CPU usage using DSM and it looks to be around 10%, so I don't think that's my issue. I've also got the RIO plugged straight into the PC and both of them have static IPs.
Can anyone point out what I'm missing? I'm sure it's probably incredibly simple...
