A transfer speed that indicates that 100,000,000 bits are transferred in one second.
A method of annotating numerical values with 10 taken as the radix.
A method of annotating numerical values with 16 taken as the radix. With each digit
movement, the value weight becomes either 16x or 1/16x.
A method of annotating numerical values with 2 taken as the radix.
CNC stands for "computer numerical control." Computer numerical control.
A connector standard that is in popular use. It is mainly used for connecting peripheral
devices to a computer. The connector shell is shaped like a "D".
A 25-pin connector with pins arranged in two rows having shell size B.
A 15-pin connector with pins arranged in two rows having shell size A.
A 15-pin connector with pins arranged in three rows having shell size E.
File containing the settings required for setting up communication between connected
devices.
An industrial network (field network) using LAN cables.
Used when performing input/output communication with output devices and input
devices. While this connection is established, other connection requests are denied.
Communication is performed at fixed cycles at each communication cycle (RPI) set by
EtherNet/IP.
Signal for identifying devices connected to a TDP/IP network. It comprises a network
address and a host address.
A network in which two or more computers are connected in a limited area by a
communication line to mutually transfer and share data.
A mode of inputting sensor signals that use NPN type transistor output for the
connection terminals and signal input section on COMBOX-NET.EIP.
A digital sensor that uses NPN type transistor output for the signal input section.
This stands for "personal computer." Personal computer.
This stands for "programmable logic controller." A controller that performs sequential
control in accordance with logical operations, sequential operation, arithmetic
operation, and other types of programs.
A mode of inputting sensor signals that use PNP type transistor output for the
connection terminals and signal input section on COMBOX-NET.EIP.
A digital sensor that uses PNP type transistor output for the signal input section.
Requested Packet Interval: Transfer interval of input/output signals
Stands for shielded twisted pair.
A device on the controlled side.
A number that indicates the position where data is stored in computer memory, hard
disk or other auxiliary storage.
A way of expressing physical quantities or states that change continuously as
continuous information.
A sensor that outputs analog values.
A connector terminal on the COMBOX-NET.EIP for input from sensors that output
analog values.
Connector or standard for connecting devices together.
A function that automatically optimizes the communication speed and communication
method with connected peer devices.
A type of output method on an electronic circuit. Specific voltage or current is not
output directly as a single but is output via an NPN transistor like a switch.
A unit of digital information consisting of eight bits. Octets are used to delimit 32-bit
IPv4 addresses into individual 8-bit units.
Cable used for communication in the up to 100 MHz band.
A single electric wire or a bundle of two or more electrical wires that is covered with a
sheath of insulating material such as vinyl.
Terminal part attached to a cable (cord) that is used for connection.
