The Logix system reaction time for any simple input to logic to output chain
consists of these five components:
1. Safety input device reaction time (plus input delay time, if applicable)
2. Safety Input Connection Reaction Time Limit
(Read from the Module Properties dialog box in the Studio 5000 Logix
Designer application, this value is a multiple of the safety input device
connection RPI.)
3. Controller reaction time (see
4. Safety Output Connection Reaction Time Limit
(Read from the Module Properties dialog box in the Studio 5000 Logix
Designer application, this value is a multiple of the safety task period.)
5. Safety output device reaction time
