You can use simple CSV file to import definition of modbus device into your Mervis IDE project.
| Name | Description |
|---|---|
| StationNumber | Modbus server address |
| Name | Variable name |
| Element | Register/Coil address. The concrete bit position (LSB=.1 to MSB=.16) or byte (.Lo or .Hi) can be specified for Registers - see examples below |
| Count | Number of modbus elements to be read/written |
| Function | Coil/DiscreteInput/InputRegister/HoldingRegister |
| Writable | Read only = 0, Read/Write = 1 |
| StType | Standard Mervis IDE variable type |
| ByteOrder | Leave empty for default byte order or specify correct byte positions as numbers from 1 to 8 (eg. 1234/3412/4321/2143 for 32 bit number) |
| K | Transformation parameter for y = Kx + Q |
| Q | Transformation parameter for y = Kx + Q |
| X1 | Alternative definition for y = Kx + Q, where the parameters are computed from [X1,Y1], [X2,Y2] points of the line. |
| Y1 | Alternative definition for y = Kx + Q, where the parameters are computed from [X1,Y1], [X2,Y2] points of the line. |
| X2 | Alternative definition for y = Kx + Q, where the parameters are computed from [X1,Y1], [X2,Y2] points of the line. |
| Y2 | Alternative definition for y = Kx + Q, where the parameters are computed from [X1,Y1], [X2,Y2] points of the line. |
