  • Page 52: Asynchronous Instructions

    Basics of program execution 6.2 Asynchronous instructions Asynchronous instructions Introduction In program processing, a differentiation 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 53 Basics of program execution 6.2 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 54 Basics of program execution 6.2 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 CREATE_DB. ①...

    Protection 7.2 Configuring access protection for the CPU Configuring access protection for the CPU Introduction The CPU offers four different access levels to limit access to specific functions. By setting up the access levels and the passwords for a CPU, you limit the functions and memory areas that are accessible without entering a password.
  • Page 62 Protection 7.2 Configuring access protection for the CPU Properties of the access levels Each access level allows unrestricted access to certain functions without entering a password, e.g. identification using the "Accessible devices" function. The CPU's default setting is "No restriction" and "No password protection". In order to protect access to a CPU, you must edit the properties of the CPU and set up a password.
  • Page 63 Protection 7.2 Configuring access protection for the CPU Configuring access levels To set the access levels for the CPU by means of parameter assignment, follow these steps: 1. Open the properties of the CPU in the Inspector window. 2. Select the "Protection & Security" area. A table with the possible access levels appears in the Inspector window.
