Mervis alarm variable
Re: Mervis HMI
I have also alarm problem. I use in Mervis alarm icon, but it wast'n change status between normal, active, active acknowledged...) Variable is BD56 SingleAlermMemoryDelay.
Second problem is delay between controller and Mervis Scada. I have done blinking alarm indicator and It refreshin too slowly. Same thing with date and time variable.
The alarm status on HMI is changed automatically according to block BD56.
- In the default quiet state, nothing can be affected.
- If an alarm is reported, it can be acknowledged.
- After the alarm ends, it can be reset in the memory to the state in point 1.
The solution to your second query is simple: For a flashing state, use a GIF image as the mapped state.
Thanks for your answer. I try a with GIF image and it working better and be visually better.
