Overview
This section contains detailed information about the following topics:
• Cycle time
• Reaction time
• Interrupt response time
• Sample calculations
Reference: Cycle time
You can view the cycle time of your user program on the PG. For further information, refer to
the
STEP 7 Online Help , or to the Configuring Hardware and Connections in STEP 7 Manual
Reference: Execution time
can be found in the S7-300 Instruction List for CPUs 31xC and 31x . This tabular list contains
the execution times for all
• STEP 7 instructions the relevant CPU can execute,
• the SFCs / SFBs integrated in the CPUs,
• the IEC functions which can be called in STEP 7.
