Handshaking - An automated process of negotiation that dynamically sets parameters of a
communications channel established between two entities before normal communication over the
channel begins.
Host
- Wireless ID of receiver.
Imports
- Values received from other devices in wireless network.
Initially On
- Upon Power cycle or updating device, the discrete output will be closed.
Interface (Level)
- Second level of fluid in tank such as water. Represented by the position of the
lower float on the digital liquid level sensor.
Interval
- Time delay in which the device will transmit data.
Jumper
- A short length of wire used temporarily to complete a circuit or to bypass a break in a
circuit. Represented by small pieces placed on pins of the circuit board.
Modbus
- A Master/Slave protocol used with programmable electronic devices that allows for
communication between many devices connected to the same network.
Modbus Master
– The Gateway’s Serial RTU port (RS232 or RS485) that polls information from
one or more Slave devices in a Modbus network.
Modbus Module
- Used when a port on a receiver is set to Modbus Master mode. Used to read
and write values to a Modbus Slave device.
Modbus Slave
- A device in a Modbus network takes action from a Modbus Master device and
responds to it.
Node
- term used to identify a System Transmitter, configured to communicate with a System
Gateway.
Node Timeout
- Transmitter setting that specifies the number of minutes the node checks for
radio-frequency activity. If it does not detect radio-frequency activity within this period, it registers a
Read Timeout error.
Normally Closed
- Digital contact that is closed in normal state.
Normally Open
- Digital contact that is open in normal state.
Output Window
- shows messages and data associated with various tasks.
Outputs
- Values used to source outputs on a device such as analog output, discrete output, or
Modbus write registers.
Parity
- A bit added to a binary code that indicates parity and is used to check the integrity of data.
A parity bit is used as the simplest form of error detecting code.
PLC
- Programmable Logic Controller.
Port
- Communications Port ID on computer used to configure devices.
Pressure Transducer
- Device used to convert pressure to an analog value.
Product (Level)
- Top level of fluid in tank such as oil. Represented by the position of the top float
on a digital liquid level sensor.
