◆ byteSwap
| boolean peripheral::GatewaySensorManager::ModbusValueEncoding8::byteSwap |
16-bit modbus words should be transferred in big-endian byte order.
For modbus devices that do not comply with this, byteSwap = true must be set. Another application is to use byteSwap to address a single byte in a 16-bit modbus word in case 8-bit values are requested (ModbusValueEncoding8).

◆ mask
| long peripheral::GatewaySensorManager::ModbusValueEncoding8::mask |
mask raw value before interpreting (0 = not masked, the same as 0xFFFF...)
Definition at line 519 of file GatewaySensorManager.idl.
◆ start
| int peripheral::GatewaySensorManager::ModbusValueEncoding8::start |
The least significant bit of the read word used in numerical interpretation.
If start is greater than 0, then one or more least significant bits remain unused. 0 is the default value. For integer values a start > 0 has mostly the same effect as using a mask = ~(2^start-1) and a scalingFactor = 1/2^start.
Definition at line 526 of file GatewaySensorManager.idl.
◆ width
| int peripheral::GatewaySensorManager::ModbusValueEncoding8::width |
Word width in bits used in numerical interpretation.
If width is smaller than the read word width, then the most significant bits remain unused. 0 is the default value. Example: 24 bit signed integer: ModbusValueEncoding32 with start = 0 and width = 24 and 'type = INT (Only for unsigned integer the use ofmask` would be sufficient.)
