Logix System Reaction Time
The following sections provide information on how to calculate the Logix system reaction
time.
Simple Input-Logic-Output Chain
This section describes the Logix system reaction time for any simple input-logic-output
chain.
Worst Case Reaction Time
The Logix system reaction time for any simple input to logic to output chain consists of
the following components.
Item | Description |
|---|---|
 | Safety input device reaction time plus input delay time, if applicable. See Configure the Safety Input Module Delay Time. |
 | Safety input connection reaction time limit. Read from the Table 2 of the
safety I/O device, this value is a multiple of the safety input device connection
RPI. |
 | Controller reaction time. See Safety Task Reaction Time. |
 | Safety output connection reaction time limit. Read from the Table 2 of the
safety I/O device, this value is a multiple of the safety task period. |
 | Safety output device reaction time. |
