Figure 8-1 Difference between asynchronous and synchronous instructionA CPU can process several asynchronous instruction jobs in parallel. The CPU processes
the jobs in parallel under the following conditions:
● Several asynchronous instruction jobs are called at the same time.
● The maximum number of simultaneously running jobs for the instruction is not exceeded.
The figure below shows the parallel processing of two jobs of the WRREC instruction. The
two instructions are executed simultaneously for a certain durationTo execute an instruction over multiple calls, the CPU must be able to uniquely relate a
subsequent call to a running job of the instruction.
To relate a call to a job, the CPU uses one of the following two mechanisms, depending on
the type of the instruction:
● Using the instance data block of the instruction (for "SFB" type)
● Using job-identifying input parameters of the instruction. These input parameters must
match in each call during processing of the asynchronous instruction.
Example: A job of the "Create_DB" instruction is identified by input parameters
LOW_LIMIT, UP_LIMIT, COUNT, ATTRIB and SRCBLK.
The following table shows which input parameters you use to identify which instructionAn 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 CREATE_DB.The input parameter REQ starts the job to execute the asynchronous instruction.
② The output parameter DONE indicates that the job was completed without error.
③ The output parameter BUSY indicates whether the job is currently being executed. When
BUSY =1, a resource is allocated for the asynchronous instruction. When BUSY = 0, the resource
is free.
④ The output parameter ERROR indicates that an error has occurred.
⑤ The output parameter STATUS/RET_VAL provides information on the status of the
The resources are
available again after a job has been processed successfully or with errors.
Example: For the RDREC instruction, an CPU can process up to 20 jobs in parallel.
If the maximum number of simultaneously running jobs for an instruction is exceeded, the
instruction returns error code 80C3 (lack of resources) in the STATUS block parameter. The
CPU stops execution of the job until a resource becomes free againSome asynchronous instructions use one or more lower-level asynchronous instructions for
their processing. This dependence is shown in the tables below.
Please note that with multiple lower-level instructions, only one lower-level resource is
typically allocated at a time.The following table shows the maximum number of simultaneously running jobs for
asynchronous instructions (Open User Communication) for the various CPUs.This chapter describes the following functions for protecting the automation
system/ET 200MP distributed I/O system against unauthorized access:he following measures additionally increase the protection against unauthorized access to
functions and data of the CPU from external sources and via the network:
● Deactivation of the Web server
● Deactivation of the OPC UA server (you can find additional information on the security
mechanisms for OPC UA server in the Communication Deactivation of the time synchronization via an NTP Server
● Deactivation of the PUT/GET communication
When you use Web server, protect your automation system against unauthorized
access:
● By setting password-protected access rights for specific users in the user administration.
