CJ1W-EIP21 Error F3

[Sergei Troizky 26]

The module falls into this error as soon as configured for IP address other than 192.168.250.x and/or subnet mask other than 255.255.255.0. For instance, 10.95.1.74- 255.255.0.0, or 192.167.6.174- 255.255.248.0. The module communication is fully functional for both EIP and FINS/TCP, but the MS LED is flashing and the display permanently scrolls the F3 error . The W465 Manual mentions the F3 error, but the remedy is absolutely unclear. Contrary to the F3 error cause listed in the Manual, the node# rotary switches are always set correctly in hex, according to the last byte of the IP address. What has to be done to get rid of the error? Any advice will be appreciated, as well as reference to other sources of information. Edited 15 Mar 2014 by Sergei Troizky

I believe the problem is that you are not calculating the node # correctly for a non-standard subnet mask. I had a similar problem a while ago. Read this thread, particularly the post by Mike Walsh. F3 Error
