Function Libraries To set up a thread: To install a program module as a thread you must run the following code to identify the module: Index := INDEXOF (module name); Afterwards, the following function just needs to be run once in order to set up the thread: CREATE_THREAD (index); FUNCTION CREATE_THREAD : BOOL VAR_INPUT NPOU_IDparam: WORD; TSLICE: WORD; RUNS: WORD; END_VAR VAR END_VAR The value returned by the function tells you something about the thread status. Value returned Explanation 0 not installed, no thread available 1 installed as thread #1 72 E 700 GB
Thread usage Function Libraries A thread's program covers a number of tasks which are more or less detached from others. Consequently, it also allows you to separately program and run these tasks. Try wrapping non-time-critical parts of the program into a thread. This will shorten the runtime of PLC_PRG and, thus, the intervals at which the process image and online communication are refreshed. Example: You wish to turn a program module called "Thread1" into a thread and have IN_00 run it. Add the following code lines to the PLC_PRG module. VAR IN00_00 AT %IX0.0: BOOL; Index1: WORD; Tslice1: WORD; Runs1: WORD; Flag1: UINT:=255; Start_Thread1: R_TRIG; Activate_Thread1: BOOL; END_VAR Start_Thread1 ( CLK:=IN_00,Q=>Activate_Thread1 ); IF Activate_Thread1 = TRUE THEN Flag1:=0; END_IF IF Flag1 = 0 THEN Index1:= INDEXOF ( Thread1 ); Flag1:= CREATE_THREAD (Index1,Tslice1,Runs1); END_IF 73
