STL - Boolean pointer looping

[davidsk2001]

Hi all, i'm working with STL code following case.

STL will continuously loop to check the condition of an array of boolean (Array[0..99] of Boolean). It will detect boolean is ON or OFF only. If condition is ON, then run a timer; if condition is OFF, then loop the pointer.

1. How do I check boolean value with pointer?
2. How do I restart pointer once it reach 99?

Thank you so much for helping me out

Siemens? TIA or 5.5?

Siemens Step 7.

I had manage to get this. But I can't get access status from my array of boolean.

L P#DBX 0.0
LAR1

L MW 2 //Check pointer below 100
L 100
>=I
JC ST02


A [AR1,P#0.0]
L S5T#2S
SD T 1
JNB ST01

A T 1
JNB ST02
L MW 2
L 1
+I
T MW 2
+AR1

ST01: L MW 2
L 1
+I
T MW 2
+AR1

ST02: NOP 0

Siemens Step 7.

Step 7 is just the brand name for the Siemens PLC programming package. It comes in two flavors: V13/TIA Portal or v5.5/Simatic Manager.

i don't know the answer,only question

if the few bool [ ] is ON what happen to the timer ON

Sorry. it is simatic manager V5.5.

If few bool[] is on, then it will run the delay timer and jump next bool[n+1] once delay timer is reach.

if bool[] is off, then it will skip the delay timer and jump next bool[n+1]

If few bool[] is on, then it will run the delay timer and jump next bool[n+1] once delay timer is reach.

if bool[] is off, then it will skip the delay timer and jump next bool[n+1]

You need to be more specific - what exactly is a "few"?

if bool [3] is ON and bool[4] is ON and bool[6] is ON timer starting/complete ,then jump to bool[5] and bool[7] ?

what will happen if previous bool repeat the process ?

what source triggering the bool ,are the triggering step by step or randomly.

what source triggering the bool ,are the triggering step by step or randomly.

For example:
bool[3] is ON, bool[4] is ON, bool[5] is OFF.

when detect bool[0] = OFF, pointer will go to bool[1] without delay timer.

it will run until bool[3] where is ON. then bool[3] will wait for delay timer to complete and go to bool[4]. bool[4] = ON, then it will also wait for delay timer to complete and go to bool[5]. bool[5] = OFF, then skip delay timer and go to bool[6] and go on.

it will keep on looping the array until bool[] go OFF.

The source trigger the bool will be trigger randomly by external code.

Code your application completely for 3 bools, and post the code as an archived library. We can then see how to expand it for 100 bools

only this come on my mind,

maybe useful maybe trash,

What about drawing a good, old flowchart? With a pencil.

Thank for the suggestion. Hereby I attach the flow chart for the whole idea. Hope everyone can understand for more.
