I had patched together, with NI's help, some TCP time server, time update VIs for my FP-2000. The FP-2000 was keeping perfect time while running LV 6.0, RT 6.1 (I think). Now, running LV 7.0, RT 7.0, the FP-2000 will throw up an error 56 every time I run the TCP connect vi. The VI functions well on my PC and appears to be functional on the v6.1 unit. Why would the TCP connection vis not function on the v7.0 FP-2000?
