| ^ Function | Coil/DiscreteInput/InputRegister/HoldingRegister | | ^ Function | Coil/DiscreteInput/InputRegister/HoldingRegister | |
| ^ Writable | 0/1 | | ^ Writable | Read only = 0, Read/Write = 1 | |
| ^ StType | Standard Mervis IDE variable type | | ^ StType | Standard Mervis IDE variable type | |
| ^ ByteOrder | Leave empty for default byte order | | ^ 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 | | ^ K | Transformation parameter for y = Kx + Q | |
| ^ Q | Transformation parameter for y = Kx + Q | | ^ Q | Transformation parameter for y = Kx + Q | |
