Dear chin_ceptual, I have chenged the following items in your codes. 1-Wrong addressing,you used edge memories again as output of function. 2-I have defined an input parameter "takt" and put the pulses (M9.0) as the input of function. 3-I enabled ENO for your function. Check the result and update here. Best regards, Hamid Hosseini AttachmentUser_def.zip (213 Downloads) |

hello, Here ALARM,ALARM_ACK,ENABLE OUT are bool out.Hence you can assign any other variable FB 21 works in following way When ALARM_ENABLE_IN & IN (Bool) both are High. Timer start with a preset value as set from MIN_DELAY_PRE(DINT) After timer is done & both ALARM_ENABLE_IN & IN are on ALARM(Bool) will be high. When OPER_ACK_ALL is high,then timer is resetted & ALARM(Bool) is OFF We are suppose to use this FB at multple locations. This FB do not works if used more than once. PLs help

Hello chin_ceptual, Check this solution,your logic changed a bit. It is working in parallel as many times as you like independently. Best regards, Hamid Hosseini AttachmentDigita_1.zip (203 Downloads) |
