Screenshot is attached below, but essentially we are chasing to try and reduce the load factor on our PLC. We have an Allen-Bradley 1756-L83ES/B PLC connected to an Ignition 8.1.4 Gateway, and we are currently seeing 350% Load Factor on one of our scan classes. The response time isn’t horrible, averaging around 25ms, but still looking to try and reduce this or at least optimize it a bit further.
In the process of trying to debug this, I noticed that the ‘System Overhead Time Slice’ settings in Logix is no longer there. Is there a new location for similar settings to look for? Or is this setting just irrelevant now on newer devices?
Any other tips on lowering the load factor? We are going to try 8.1.7 when we have a break on the line to try and see if the new load factor calculation shows acceptable data, but I have a feeling its not going to bring it down to a reasonable number.
