Try moving your alarm log to an external card. Most of the time it goes better from there. Greetz |

Hi, It goes with Acquisition Cycle for your Alarm Word which is defined in the Tags. The scan time is slower than the alarm cycle time so the device panel can't capture the alarm. 1. Check each alarm separately to make sure you see the activation, deactivation, and whether they get acknowledged. You can add a memory flag in parallel to the bit in the plc and simulate the alarm. 2. Reduce the scan time of the Alarm word in tag area 3. It is better to latch the alarm and add an Ack button to the HMI. This way you won't miss any alarm. Regards, Behnam www.winccflexiblemastery.com |
