so the solution is good and will work.<br/>
same is btw for almost all analog signals you will have to check the bounds.</p>
<p>for this state machine look at w <a class="" href="http://www.oscat.de" rel="nofollow">www.oscat.de</a> w <br/>
or have a look in SFC here you can do exactly same, as this chart is designed for this type of statemachines.</p></div>ST Condition " CASE...

change the if case to >=...<br/>
IF inputtime>=t#5s THEN<br/>
then it works<br/>

Hi,<br/>
I have noticed a very interesting problem in CodeSys 2.3. Actaully I am using CodeSys SP RTE target PCAN PCI. Everything is ok. As I can get all "StatusWORD" signal from my Canopen Node. But problem is like that:</p>
<p>If I have written a very simple program in ST for "CASE... OF" condition , It works only in Simulation mode but when I load it in RTE SP PLC then it build & runs but it does not change the "CASE..OF" State. Case state has no change, it goes only in State 0: as it is first commnad but not State 1 or further. But in simulation , it works fine in all State.</p>
<p>calltimer;<br/>
inputtime:=calltimer.timeroutput;</p>
<p><span style="color: #4040FF;">CASE state OF<br/>
0: output:=4;<br/>
IF inputtime=t#5s THEN state:=State+1; END_IF;<br/>
1: output:=5;<br/>
IF inputtime=t#10s THEN state:=State+1;END_IF;<br/>
2: output:=90;<br/>
IF inputtime=t#15s THEN state:=3;END_IF;<br/>
3: output:=80;<br/>
IF inputtime=t#20s THEN state:=state+1;END_IF;<br/>
4: output:=12;<br/>
IF inputtime=t#25sTHEN state:=0;END_IF;<br/>
END_CASE;</span></p>
<p>But this program is ok in Simulation Mode It change the State from 0 to1, 1 to 2, 2 to 3. 3 to 4.<br/>
But when I load this program in CoDesys SP RTE, then It runs but No chage of "state". That means "CASE... of " operation is not working.<br/>
I have need suggestion because i have to use this "Case..OF" state ment for CANopen State Machine to take in opeartion.</p>
<p>Thanks <br/>
Asif</p></div>
