Several Operator Panels on Several NCUs,
Distributed Systems (B3)
2.1

Brief Description

2.1.1

Topology of distributed system configurations

Features
Rotary indexing machines, multi-spindle turning machines and complex NC production
centers all exhibit one or more of the following features:
● More than one NCU due to large number of axes and channels
● Large dimensions and spatial separation necessitate several control units (OP/TP
● Modular machine concept, e.g. through distributed control cubicles
Distributed system configuration
The two areas highlighted in the topology display identify two communications functions to
be examined separately in terms of configuration and utilization.
An operator panel generally comprises an OP/TP with a PCU on which the HMI software
runs. If several OPs/TPs are to be connected to a PCU, TCUs are required in addition.
