Measurement settings
The measurement settings reflect the configuration possibilities for mapping a measurement to an Modbus address range and function code.
Address
Description: The Modbus address to start reading registers from.
Required: yes
Default value: 0
CollectionType
Description: The way this measurement should be collected from the OPC-DA server.
Required: yes
Default value: polled
Options: polled | monitored
Checkout the data collection methods section for more information.
CollectionInterval
Description: The interval in milliseconds at which this measurement should be collected.
Required: no
Default value: 5000
CollectionOffset
Description: The offset in milliseconds, relative to the 0th second of a minute, at which this measurement should be collected. Only relevant for polled measurements.
Required: no
Default value: 0
RegisterType
Description: The Modbus register type to read.
Required: yes
Default value: Input Register
Options: Coil | Discrete Input | Input Register | Holding Register
ModbusDataType
Description: The datatype of the Modbus registers to read. If the input register is Discrete Input or Coil only boolean is allowed.
Required: yes
Options: boolean | uint16 | int16 | uint32 | int32 | float32 | uint64 | int64 | float64
ByteOrder
Description: The Modbus byte order to interpret the register bytes: AB|BA-(CD|DC)-(EF|FE-GH|HG). Optional and overwrites the collector ByteOrderDefault.
Required: no
Default value: Default
Options: Default | AB-(CD)-(EF-GH) | BA-(DC)-(FE-HG) | (HG-FE)-(DC)-BA | (GH-EF)-(CD)-AB
