Consider Configuration with Red. AC800M (PM866) and Red. CI854. All I/O modules used in configuraiton are S800 I/O's and are connected to Controller using FCI CI840.
1. Does I\O on Profibus cause an impact of CPU Cylic Load ?. In most of manuals I have read that profibus does not cause any impact on CPU Load as it is managed by CI854. But what about load for reading data structure from CI854 to Controller ?
2. How much of Cyclic Load is acounted for Variable copying (i.e Reading\ Writing a Variable value from\to I\O channel. This is up & above the cylic load contributed by Runtime POU instances for an application.
