Our HMI is slow to update some PLC tags. I noticed the PLC project has only one continuous task and it is using about 80% of CPU. Is that too much? It's CLGX5K L71 with eight I/O cards. What is the optimum percentage of PLC CPU usage of a continuous task? If 80% is too much, does that mean some of the continuous task should be rewritten to be periodic tasks?
