Host Link
Host computer or OMRON PT (Programmable Terminal) 1) Various control commands
such as reading and writing
I/O memory, changing the
operating mode, and force-
setting/resetting bits can be
executed by sending C-
mode host link commands
or FINS commands from the
host computer to the CPU
Unit.
2) It is also possible to send
FINS commands from the
CPU Unit to the host com-
puter to send data or infor-
mation.
Use Host Link communica-
tions to monitor data, such as
operating status, error informa-
tion, and quality data in the
PLC or send data, such as pro-
duction planning information, to
the PLC.
