OPC UA Client and Server
Openness, Productivity and Connectivity – unified architecture, now including Alarms and Conditions
Client
- Parallel connection to multiple external UA servers
- Subscription to values without programming
- Write values without programming
- Current subscription values are automatically available in the process image
- API for OPC UA Method Call
- Library of PLCopen function blocks included for easier programming
- Library of C/C++ functions also included
Server Data Access
- Maps the supply of variables of the controller in the address space
- Address space can be modelled entirely independently of the controller software in order to emulate Companion Specifications
- Takes into consideration the user-specific access rights to variables which are managed in the M1 system
- Logging of write accesses
Server Alarms & Conditions
- Automatic monitoring of variable values
- Discrete alarms and level alarms (High, HighHigh etc.)
- Selectable predefined acknowledge models
- Configuration (variables, limits etc.) in CSV format, configurator integrated in the SolutionCenter
- Discrete alarms are also possible without reference to a variable
- Extensive API for PLC function block library and C/C++: Generation and changing of monitoring tasks, acknowledge, status queries etc.
