Brief description

2.1.1

Several operator panels on several NCUs (T:M:N)

Under certain circumstances, a single operator control and monitoring station may not be
sufficient for complex plants and machines. Therefore, several operator control and
monitoring stations in a SINUMERIK system network (Ethernet) can be connected to several
numerical controls (NCU) via a PCU in such a way that they enable flexible and distributed
operation and monitoring of the entire system.
The following figure provides an overview of the components that currently can be connected
in a system network to form an operator control and monitoring system T:1:N. Meanings:
● T: Thin Client Unit (TCU) or HT8 handheld unit (connected to the PCU)
● 1 (M): Man Machine Control (MMC), PCU 50.x with SINUMERIK Operate
● N: Numeric Control Unit (NCU), NCU 7x0.3 PN
