Cun Posts: 2 Rating: (0)	Hi is it possible to automaticly reset a memory bit after exiting a fc for example In OB1 When calling FC1 with I0.0 Thenpressing i0.1wich makes m30.0 true his then turnQ0.0true in OB1 But when i keep I0.1 and M30.0true and exit FC1 by not operating I0.0 Q0.0 is still set . Is there a simple way to reset the bit memory automaticly after exiting a function or Function block Attachment C:\Documents and Settings\plc09\My Documents\untitled.JPG (113 Downloads)

Note ENO is not designed for such uses but Check here for more information: cases on BR-EN/ENO Mechanism Best regards Hamid Hosseini

At this moment if you remove FC1 calling by removing I0.0 then last status of M30.0 remains true (withold) and hence Q0.0 remain TRUE. So in network 2 of OB1 you can write something like this: ----------\|/\|--------------(R) I0.0 M30.0 So when FC1 is not being called M30.0 will go OFF and will make Q0.0 OFF too. In network three of OB1 keep your line as it is.
