OMRON FINS: error code 'the specified node is already connected'

[montanarin 0]

Hi everybody, i need your help with fins omron and vb.net. I correctly write and read PLC data, but i would like to simulate a PC or a communication via ethernet trouble. So i disconneted the ethernet cable connetting the PLC (server) o LAN. NB: the keep alive time is set on default value ('0' or 120 min.); client and server node are fixed (240 PC, 101 PLC). I riconnected the cable after some minutes. The VB application send a new FINS NODE ADDRESS DATA SEND (CLIENT TO SERVER) Command, fixing his Node address at 240. The response i read is: F I N S 00 00 00 10 00 00 00 01 00 00 00 21 (The specified node is already connected) 00 00 00 F0 00 00 00 65 Which command i have to send via FINS, now? i think after this response the communication via fins is not regular; what i have to send for reset the comunication and retry from FINS NODE ADDRESS DATA SEND (CLIENT TO SERVER) Command? thank for help Matteo M.
