State Animation for SCADA
Full Name
Lib.Mervis.v1_0.ScadaAnimation
Required Project References
- Lib.Mervis
Description
An auxiliary block used for generating state numbers for the animation of operation and alarm for SCADA.
Usage in ST
program test
var
inp: lib.mervis.v1_0.ScadaAnimation;
end_var
inp();
end_program
Inputs
| Name | Data Type | Retain | Must Connect | Meaning | |
| CompositeState | uint | No | Yes | Composite state, see for example SwitcherBlock v1.2 - Composite state | |
| UseFeedbackForRun | bool | No | No | Determines whether the run state is taken from the feedback value (=true) or command value (=false) |
Outputs
| Name | Data Type | Meaning | |||||||||||||||||
| StateNumber | int | State number according to CompositeState. If there are multiple states, they change sequentially with a period of one second. Each state has its priority. If the input satisfies multiple states, the output is the one with higher priority (e.g., the technology reports a fault but is in operation) | Number | Priority | Meaning | 0 | 1 | Off | 1 → 2 → 3 → 1… | 2 | Running | 4 → 5 → 4… | 3 | Fault | |||||
Detailed Function Description
The block is used for animating the state of a controlled element. It cyclically changes the state number, thus allowing the assignment of individual animation phases. A typical use is with Weintek HMI displays.
