Logix System Reaction Time for Simple Input-logic-output Chain
The Logix System Reaction Time for any simple input-logic-output
chain consists of the following five components:
1. Input module delay time
2. Input data transfer time via the input connection
3. Controller processing time (Logic)
4. Output data transfer time via the output connection
5. 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.
