TERMS
Unless otherwise specified, this manual uses the following terms.
Term Description
Cyclic transmission A function by which data are periodically exchanged among stations on the same network using link
devices on CC-Link IE Field Network Basic
Disconnection A process of stopping data link if a data link error occurs
I/O combined module A generic term for CC-Link IE Field Network Basic remote I/O modules where a digital signal can be input
and output
I/O module A generic term for CC-Link IE Field Network Basic remote I/O modules
Input module A generic term for CC-Link IE Field Network Basic remote I/O modules where a digital signal can be input
Label A label that represents a device in a given character string
Link device A device (RX, RY, RWr, RWw) in a CPU module that is used for communications with a slave station
Link scan (link scan time) After sending requests to all the slave stations and then receiving the responses from all the slave
stations, the master station on CC-Link IE Field Network Basic starts sending another request to the slave
stations. The link scan time is a time period taken for the master station to start sending another request
after sending the previous requests.
Master station A station that controls the entire CC-Link IE Field Network Basic. Only one master station can be used in
a network.
Output module A generic term for CC-Link IE Field Network Basic remote I/O modules where a digital signal can be
output
Reference response time A time period taken from when a slave station on CC-Link IE Field Network Basic receives a request from
the master station until it returns the response to the master station.
Remote input (RX) Bit data input from a slave station to the master station
Remote output (RY) Bit data output from the master station to a slave station
Remote register (RWr) Word data input from a slave station to the master station
Remote register (RWw) Word data output from the master station to a slave station
Reserved station A station reserved for future use. This station is not actually connected on CC-Link IE Field Network
Basic, but counted as a connected station
Slave station A station that performs cyclic transmission with the master station on CC-Link IE Field Network Basic. The
station exchanges I/O signals (bit data)/I/O data (word data) with another station.
SLMP The abbreviation for Seamless Message Protocol. This protocol is used to access an SLMP-compatible
device or a programmable controller connected to an SLMP-compatible device from an external device.
Subnet mask A number used to logically divide one network into multiple subnetworks and manage them easily. The
following Ethernet network systems can be configured:
• A small-scale Ethernet network system in which multiple network devices are connected
• A medium- or large-scale network system in which multiple small-scale network systems are connected
via routers or other network communication devices
