Hello All,
I was recently tasked with updating the firmware on all our Micrologix 1100s to v16. I took processors from the bench, flashed them with v16, then downloaded the appropriate programs, and then switched them out with the ones in the field. Since doing so I've been experiencing intermittent comm issues. I have 2 processors that are loosing and reestablishing comms at random intervals but it's happening at about every 30 secs. But also at times they are losing comms for a long enough period to trigger alarms (5 mins). There are several others processors that are dropping and reestablishing comms as well but not as frequently. Before updating and switching out the processors there was never this type of frequency with comm loss and I am wondering if there are known issues with the newer firmware version that explains the issue I am having.
I'm also wondering if it could it be something with the network that they're on? They all use radio transmitters for Ethernet connectivity so maybe disconnecting from the transmitter caused some kind of problem?
Also, when flashing the processors, I connected via serial cable and had to reset the DCOMM settings to default to establish the connection. However the programs that were downloaded all used Ethernet drivers for communication but maybe that caused an issue??
I have been able to connect remotely over Ethernet so my thought is that it's not a processor issue and more of a network issue but I don't know.
I'm just trying to narrow it down, so any help is much appreciated
Thanks,
-Kyle
