We have Real Time Automation's 435NBX module, used to access one serial device over EthernetIP network.
It seems this device gets stuck and stops exchanging data between PLC and serial device. What I see when I connect directly to it is that's inaccessible, cannot see it on network or through RTA program used to set IP address.
What solves the problem is rebooting the device by power off and on, after that it's pingable, can be seen on PLC's network, and through RTA program for setting IP address. And it starts communicating.
This happened second day in a row now.
Anyone have any idea what could be the issue? Is it possible that we try to read/write too fast? Right now we read/write data as soon as 435NBX says it's ready to recieve/send.
