<div class="markdown_content"><p>I do it other way.</p> <p>and no you can not force in puts and outputs direct only internal memory points.</p> <p>In simulation it is no problem but in real time online it is impossible as it should.</p> <p>For this purpose you can use an OR/AND port on the inputs.</p> <p>I work a lot with alarms and i have a switch in software to look at the input or on the forced points </p> <p>SEL (simulation, input,off,on)</p> <p>this works same for analog inputs.</p> <p>for outputs i do same</p> <p>SEL(forcing,normal,off,on)</p> <p>They are in seperate POU so i can see what happens and i can change them easily without searching all POU's.</p></div>

<div class="markdown_content"><p>Hello everybody,</p> <p>I have a question about the forcing of variables.</p> <p>I Have a project that is written in CFC. The inputs to the system are CANopen I/O. If i go online and force an input it looks forced but it seems like the PLC is overwriting it the next cycle </p> <p>If i try to force an output on a CANopen node it also gets overwritten the next cycle. I can force it by putting the PLC in stop... and the force the output </p> <p>Is it not possible to force I/O???</p> <p>/Hasse</p></div>
