8-9. Terminology
A relay which controls any series of programs with its operation. If the
master control relay is de-energized, all of the contacts and devices
controlled by the master control relay are de-energized.
A half-duplex communication protocol for FP series programmable
controllers that performs communication between a computer and
programmable controllers.
Abbreviation for MOdulator/DEModulator. The modem modulates digital
signals and transmits them through a telephone line.
The bit which represents the greatest value in a byte, word, or double-word.
The digit which represents the greatest value in a number.
A communication link in which one host can communicate with two or more
stations.
Random, unexpected electrical signals, that are caused by radio waves or by
electrical or magnetic fields.
The memory area whose contents will be lost or modified if operating power
is lost or if the mode of the programmable controller is changed from RUN
to PROG.
A contact which is closed when the coil of the relay is not activated.
A contact which is open when the coil of the relay is not activated.
Not being in continuous communication with another processor.
Being in continuous communication with another processor.
The act of exceeding the maximum limit in a registers capacity.
A check method for the number of 1s in a character when data
communication is performed. The parity check is performed by calculating
the number of ones in a character.
Devices that are connected to the programmable controller.
Abbreviation for Programmable Logic Controller. See programmable
controller.
A simple transducer which works based on resistance change. The FP1
manual-set registers work according to the potentiometers named “V0”,
“V1”, “V2”, or “V3”.
A control device which can be programmed to control process or machine
operations. A programmable controller is often referred to as a PLC when
abbreviated.
Random Access Memory. RAM provides an excellent means for easily
creating and altering a program. Many of the FP series programmable
controllers use RAM with battery backup for the application memory.
