Cyclic Program Execution - Siemens Simatic S7-1500 Function Manual

Cyclic program execution

Validity
The statements of the section "Cyclic program execution" apply to the CPU components of
the following systems:
● S7-1500 automation system
● ET 200MP and ET 200SP distributed I/O systems
● CPU 1516pro-2 PN of the ET 200pro distributed I/O system
● S7-1500R/H redundant system (in RUN-Solo system state)
In RUN-Redundant system state, the statements of section "Cycle and response times of
the S7-1500R/H redundant system (Page 51)" apply.
Restrictions
With the S7-1500R/H redundant system, there are restrictions compared to the S7-1500
automation system. The S7-1500R/H redundant system does not support all hardware
properties and firmware functions of the S7-1500 automation system (for example, it does
not support PROFIBUS DP, central I/O, web server, etc.).
The restrictions are described in the S7-1500R/H redundant system
(https://support.industry.siemens.com/cs/ww/en/view/109754833) system manual.
