Logix System Reaction Time for Input-Controller A Logic-Controller B Logic-Output
Chain
The Logix System Reaction Time for any input-controller A
logic-controller B logic-output chain consists of the following seven
components:
1. Input module delay time
2. Input data transfer time via the input connection
3. Controller processing time (Logic)
4. Produced/Consumed data transfer time via the
produced/consumed connection
5. Controller processing time (Logic)
6. Output data transfer time via the output connection
7. Output module delay time
To aid you in determining the reaction time of your particular control
loop, a Microsoft Excel spreadsheet is available in the Tools folder of
the RSLogix 5000 software CD.
