I am currently using a 1756-EN2T with firmware 5.28
The CPU utilization starts at about 50% and will slowly creep up over the next 60mins all the way to 100%. The connections remain at 50. After a few minutes at 100%, I am unable to connect to the EN2T to view the diagnostic screen. I am still able to ping it.
At this point, if I go offline, it wont allow me to connect anymore.
The only way around this is to power down the EN2T.
I am using cisco SG-300-10 switches. One configured as Layer 3 while the others are Layer 2. IGMP snooping is enabled. There are about 8 cisco switchs on this machine in a start topology. 10 Redlion HMI's. 10 - 1734-AENT. 3 Kinetix 300 drives. 2 Realtime automation devicenet to ethernet/IP gateways. 11 Festo Ethernet/IP valve banks. 1 DVT camera. and 1 Keyence camera. 3 Labview and 1 VB application communicating ethernet/IP.
When I am able to look at the diagostic screens on the EN2T, I dont see the number of connections increasing, just the cpu utilization.
All the devices on the network are set for 60RPI except the kinetix 300 which is set for 20RPI
From my understanding, TCP and CIP connections have different max connection values. But for some reason, when I cant connect to the EN2T through the webserver, I also cant make additional CIP connection.
Any Ideas?
