Product description
 | The described product is replaced by the product TF6100 TC3 OPC UA. |
OPC stands for "Openess Productivity and Collaboration" and describes an initiative for standardisation of data exchange in automation. Beckhoff is an active member of the OPC Foundation. (More information about OPC may be obtained under www.opcfoundation.org ) The OPC standard specifies the communication of industrial process data between sensors, instruments, controllers and software systems. An OPC-Server is a software component, which offers an OPC interface to other applications. The TwinCAT 3 Function TF6120 OPC-DA contains such an OPC-Server and provides the following features:
- OPC Specification 1.0a and 2.0
- Free choice of TwinCAT devices (ADS devices): PLC / IO / NC / CAM / ...
- Access via TwinCAT PLC / TwinCAT I/O or bus controller to all the fieldbusses supported by TwinCAT (Lightbus / Profibus DP / Interbus-S / CANopen / DeviceNet / ...)
- Access to TwinCAT variables by address / by name / by generic ADS IndexGroup and IndexOffset
- Optimal access to data from the OPC server on TwinCAT variables
- Simulation mode (sinus, ramp, random) for variables
(i.e. testing an OPC client/server communication without access to physical I/O) - Easy, one-time only configuration by XML
- OPC XML DA Server
Integration into the TwinCAT system
The OPC server creates the connection to the TwinCAT system as a gateway via ADS, and offers OPC clients the specified OPC-DA / AE interface.
What is included
