Overview
- 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
Features of the evaluation version
The evaluation version is a fully functional version with a 30 days time limitation. The OPC server then switches to its internal simulation mode. All the process values are then simulated, and there is no longer any access to the ADS devices.
The time limit in the evaluation version can be removed by purchasing a TwinCAT OPC software licence, and by the entry of a valid registration key.
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.
System requirements
- Microsoft Windows NT 4 / Windows 2000 / XP
