Abbreviation for QJ61BT11 Control & Communication Link System Master/Local
Module
Transmission method by which to periodically communicate the contents of remote
I/O and remote registers.
Transmission method with which the counterpart is specified and 1:1 communication
is used at an arbitrary timing.
Station that controls the data link system.
One master station is required for each system.
Station having a PLC CPU and the ability to communicate with the master and other
local stations.
Remote station that handles bit unit data only. (Performs input and output with
external devices.) (AJ65BTB1-16D, AJ65SBTB1-16D)
Remote station that handles bit unit and word unit data only. (Performs input and
output with external devices, and analog data conversion.)
(AJ65BT-64AD, AJ65BT-64DAV, AJ65BT-64DAI)
Generic term for remote I/O station and remote device station.
(Controlled by the master station)
Station that can perform transient transmission, such as the AJ65BT-R2 (including
local stations).
Backup station for data link control when the link to the master station is disconnected
due to a PLC CPU or power supply problem.

Bit unit information that indicates the module operating status and data link status of
the master station/local station. (Expressed as SB for convenience)
Link special register (for CC-Link)
16-bit unit information that indicates the module operating status and data link status
of the master station/local station. (Expressed as SW for convenience)
Remote input (for CC-Link)
Information entered in bit units from the remote station to the master station.
(Expressed as RX for convenience)
Remote output (for CC-Link)
Information output in bit units from the master station to the remote station.
