Periodically my company is seeing a spike in the load factor on two of our connections to our PLCs. The effects are visible on the HMI and things slow down and sometimes database queries fail. Is a load factor higher than 100% a strong indicator of a problem?
PLC1 <–> Gateway 268% Load Factor
PLC2 <—> Switch1 <—> Switch2 <—> Gateway 106% Load Factor
Below are pictures of the load factor.
