Overview

Overview
The SINUMERIK OPC UA server provides the possibility to communicate with SINUMERIK
via OPC UA. The following functionalities of the OPC UA specification are supported by the
server:
● Data Access:
● Alarms & Conditions: Event based provision of SINUMERIK alarms and messages from
HMI, NC and PLC
● Methods:
This chapter describes the address space of the SINUMERIK OPC UA server and gives further
information how to address some SINUMERIK specific values. Especially since a lot of
SINUMERIK values are stored in arrays or matrices.
Furthermore the SINUMERIK alarm object is explained and it is shown how to get the alarms
