7.3.1 Overview
Definition of Response Time
The response time is the time from an input signal being detected to changing an output
signal linked to it.
Variation
The actual response time is lies somewhere between a minimum and maximum response
time. For configuring your system, you must always reckon with the longest reaction time.
The shortest and longest response times are analyzed below so that you can gain an
impression of the variation of the reaction time.
Factors
The reaction time depends on the cycle time and on the following factors:
• Delay of the inputs and outputs of signal modules or integrated I/O.
• Additional DP cycle times on the PROFIBUS DP network
• Execution of the user program
Reference
Further information
• about delay times can be found in the Technical Specifications of the signal modules
(
Module data Reference Manual).
• about delay times for the integrated inputs and outputs can be found in chapter
