also include PTs as Polled
Units via 1:N NT Links.
Note Serial PLC Links can be
created on serial port 1
or serial port 2, but not
on both ports at the
same time.
Data can be exchanged with
PTs without using a communi-
cations program in the CPU
Unit.
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.
