For exchange data with 3 PLC FX3U ENET i used FX3U ENET modul and i follow the example from the Mitsuibihi site, with an UDP connection.
In this mode i have no problem with UDP connection (one PLC it's connected with WLAN) but it's very strange the TCP connection status on the moduls.
The first modul, have a GX Developer connection for assistence, but i can't communicated with the modul with this channel, in the same time of UDP. Also another connection with a MAC 405 can't exchange data in the same time UDP. To use GX connection or MAC connection, i must to deleted the UDP channel from the modul.
In the second modul, the GX connection sometime it's OK, sometime no, the timeout it's over the second also for the ping test and the connection test for the GX Developer. In this modul i don't have the MAC connection. Another information it's, that i watch the status PLC with GX Developer with TCP (when function) the cycle time it's 64 ms, but if i use the serial port, the cycle time it's 30:32 ms.
In the third modul, it's all OK, UDP and TCP, i can test the PLC from WLAN without problem.
In the manual the only limit it's for 4 connection MC, non other limit i found. The problem it's not in the hardware beacuse i just exchange the moduls on the other position and the results are the same.
It's possibile some problem with the timing ?
Bye
