Problem Faced:
• We are unable to connect with CPU via Rslogix 5000
• Whenever we try connecting we receive an error “Error 701-8004250A.Failed to go online with controller. Unable to Open connection—All connections may be in use”. Please refer the below image
• Everything was fine till few days ago & we are able to go online.
• Attached is the overall system Topology for your reference.( system Topology.pdf)
• Please refer below the screen shoots taken using Logix5000 task monitor utility. Apparently we have 262 available connections & we are not using more than 40 .Additionally CPU utilization also seems reasonable around 13 %,
Controlnet CPU usage is 100 %
• Furthermore when we browse Rslinx, we cannot see the secondary CPU. Please refer the below image
• When we are trying to upload from RSnetworx, we cannot see secondary CPU & the error code CNET:8222 is appearing. Please refer the attached snapshots
• System Overhead slice time is currently at 20%
NUT is 5msec & RPI is 40msec
• We are able to receive data in DCS & all IOs are also OK. Both CPUs are synched & all LEDs are OK (all Solid Green) but we are not able to go online with the CPU.
