High-speed/
Long-distance
Communications with
CompoBus/S
A CompoBus/S Master Unit can be included in the CQM1H. High-speed or
long-distance remote I/O communications can be performed with CompoBus/
S Slaves. (The CompoBus/S Master Unit is a Dedicated I/O Unit for the
CQM1H.)
A Wide Range of HMI
Monitoring and Setting
Methods
Programming Devices and Programmable Terminals (PTs) can be connected
to up to four ports, two ports on the CPU Unit and two ports on a Serial Com-
munications Board. It is thus possible to set up and monitor machine control
from a PT while monitoring or programming from a Programming Console or a
personal computer.
