Plat
The Plat is a component, which shows the device’s main parameters. This component is placed under the Service component, and is associated with the device hardware.
The plat component has the following slots:
- Status: shows the platform status;
- Platform ID: shows the platform ID;
- Platform Ver: shows the platform version;
- Mem Available: shows the RAM memory available in the controller;
Note: The whole application for the iSMA-B-FCU device cannot exceed 64 kB.
- Cpu Usage: shows the CPU usage from the last 5 seconds;
- Firmware Version: shows the controller’s firmware version;
- Nv Behavior If Empty: if the non-volatile memory is empty after copying the NV component output value will be 0 (Leave 0 option) or copy value from Default slot (Copy From Default option), the default option is to copy the value from the Default slot;
- Nv Free Numeric: shows the number of available numeric non-volatile components;
- NV Free Boolean: shows the number of available Boolean non-volatile components.
Note: Number of components physically added to the application does not have to be equal to memory cells. It can be calculated in the way shown below:
- Each added NV Numeric (or Integer) component (not NV Net component) uses two memory cells–one numeric cell for value and one Boolean cell for Hand/Auto mode;
- Each added NV Boolean component (not NV Net component) uses two Boolean memory cells–one for value and one cell for Hand/Auto mode;
- Each NV Net Numeric component uses one numeric cell–these components work only in the Auto mode, so the memory cell is required only for the value;
- Each NV Net Boolean component uses one Boolean cell–these components work only in the Auto mode, so the memory cell is required only for the value;
- For Example, if 2 NV Numeric components, 3 NV Boolean components, 4 NV Net Numeric components, and 5 NV Net components are added to the application, the usage of memory cells can be calculated as follows:
Type of Component | Number of Components | Used Boolean Memory Cells | Used Numeric Memory Cells |
|---|---|---|---|
NV Numeric | 2 | 2 (for Auto/Hand modes) | 2 (for values) |
NV Boolean | 3 | 6 (3 for Auto/Hand modes and 3 for values) | 0 |
NV Net Numeric | 4 | 0 | 4 (for values) |
NV Net Boolean | 5 | 5 (for values) | 0 |
Total | 13 | 6 |
As presented in the table, this application uses 13 Boolean memory cells and 6 numeric memory cells. In this case, the Free NV Boolean and Free NV Numeric slots (under the plat component) will display:
- Free NV Boolean: 227
227 = 240 (available Boolean memory cells) – 13 (Boolean memory cell used in application)
- Free NV Numeric: 224
224 = 230 (available Numeric memory cells) – 6 (Numeric memory cell used in application)
The plat component offers the following actions, available in the context menu:
- Restart: restarts the application (Sedona Virtual Machine);
- Reboot: reboots the device;
- Copy From Nv To Default: copies values from the Out slot to the Default slot in all NV components (see the NV component chapter);
- Copy From Nv To User: copies values from the Out slot to the User slot in all NV components (see the NV component chapter);
- Copy From Default To NV: copies values from the Default slot to the Out slot in all NV components (see the NV component chapter);
- Copy From User To NV: copies values from the User slot to the Out slot in all NV components (see the NV component chapter);
- Set All Nv In Auto: sets all NV components in the auto mode.
