Page 162: Asynchronous Instructions
Basics of program execution 7.5 Asynchronous instructions Asynchronous instructions Introduction During program execution a distinction is made between synchronous and asynchronous instructions. The "synchronous" and "asynchronous" properties relate to the temporal relationship between the call and execution of the instruction. The following applies to synchronous instructions: When the call of a synchronous instruction is complete, execution of the instruction is also complete.
Page 163 Basics of program execution 7.5 Asynchronous instructions Difference between synchronous/asynchronous instructions The figure below shows the difference between the processing of an asynchronous instruction and a synchronous instruction. In the figure below, an asynchronous instruction is called in five cycles before execution is completed, for example, a data record is transferred in full.
Page 164 Basics of program execution 7.5 Asynchronous instructions Parallel processing of asynchronous instruction jobs A CPU can process several asynchronous instruction jobs in parallel. The CPU processes the jobs in parallel under the following conditions: ● Jobs for an asynchronous instruction are started while other jobs for that instruction are still running.
Page 165 Basics of program execution 7.5 Asynchronous instructions Status of an asynchronous instruction An asynchronous instruction shows its status via the block parameters STATUS/RET_VAL and BUSY. Many asynchronous instructions also use the block parameters DONE and ERROR. The figure below shows the two asynchronous instructions WRREC and RD_DPARA. ①...
Page 166 Basics of program execution 7.5 Asynchronous instructions Summary The table below provides you with an overview of the relationships described above. It shows in particular the possible values of the output parameters if execution of the instruction is not complete after a call. Note You must evaluate the relevant output parameters in your program after each call Table 7- 5...
Page 167 Basics of program execution 7.5 Asynchronous instructions Use of resources Asynchronous instructions use resources in the CPU during their execution. The resources are limited depending on the type of CPU and instruction. The CPU can only simultaneously process a set maximum number of asynchronous instruction jobs. The resources are available again after a job has been processed successfully or with errors.

Commissioning 9.4 Operating and system states Operating and system states 9.4.1 Overview Operating states Operating states describe the behavior of an individual CPU at a specific time. Knowledge of the operating states of the CPUs is useful for programming startup, testing and error diagnostics.
Page 199 Commissioning 9.4 Operating and system states Synchronization for redundant mode In the SYNCUP system state, the operating system synchronizes the user programs in the two CPUs for redundant operation. Synchronization ensures that both CPUs can operate redundantly. In the event of failure of the primary CPU in redundant operation, the backup CPU takes over control of the process as the new primary CPU at the point of interruption.
Page 200 Commissioning 9.4 Operating and system states Overview of system and operating states The figure below shows the possible operating states of the CPUs and the resulting system states. In general, the two CPUs have equal priority; each CPU can be either primary or backup. The CPU that you switch from STOP to RUN first becomes the primary CPU.
Page 201: Startup Operating State
Commissioning 9.4 Operating and system states The table below gives an overview of how the redundant system starts up as well as the various operating and system states that it goes through in the process. The following initial situation and steps are an example. The operating and system states are described in detail in the following sections.

Page 318 Glossary Organization block Organization blocks (OBs) form the interface between the operating system of the CPU and the user program. The organization blocks determine the order in which the user program is executed. Pairing Pairing is the mutual recognition of the CPUs of an S7-1500R/H system within a network. During pairing, the CPUs exchange information for mutual identification.
Page 319 Glossary Primary-backup switchover The primary CPU has the leading role within the redundant system. If the primary CPU fails following a fault, the backup CPU takes over the primary role and operates as the primary CPU. Process image (I/O) The CPU transfers the values from the input and output modules to this memory area. At the start of the cyclic program, the CPU transfers the process image output as a signal state to the output modules.
Page 320 Glossary Redundancy connection/redundancy connections The redundancy connection in an S7-1500R system is the PROFINET ring with MRP. The redundancy connection uses part of the bandwidth on the PROFINET cable for the synchronization of the CPUs. This bandwidth is therefore not available for PROFINET IO communication.
Page 321 Glossary SELV Safety Extra Low Voltage = Safety extra-low voltage SNMP SNMP (Simple Network Management Protocol) is the standardized protocol for performing diagnostics on and assigning parameters to the Ethernet network infrastructure. In the office setting and in automation engineering, devices from a wide range of vendors on the Ethernet support SNMP.
Page 322 Glossary System states The system states of the S7-1500R/H redundant system result from the operating states of the primary and backup CPU. The term system state is used as a simplified expression that refers to the operating states that occur simultaneously on both CPUs. The S7-1500R/H redundant system has the system states STOP, STARTUP, RUN-Solo, SYNCUP and RUN- Redundant.
Page 323 Glossary User program In SIMATIC, a distinction is made between user programs and the firmware of the CPU. The user program contains all instructions, declarations and data that control a system or process. The user program is assigned to the redundant system. Structuring into smaller unit is supported.
