Connection of VME based PLC systems to ibaPDA-V6 or ibaLogic
The ibaLink-VME card can be used to connect VME based PLC systems via fiber optics to the data capturing system ibaPDA-V6 or the Soft-PLC ibaLogic in order to transfer measured data.
ibaLink-VME is the successor of the ibaLink-SM-128Vi-2o card and completely compatible with the previous functions in 3Mbit mode. Moreover ibaLink-VME offers new functions using the ibaNet protocols 32Mbit and 32Mbit Flex.
Depending on the ibaNet protocol the card supports different applications:
This mode is compatible with the predecessor ibaLink-SM-128V-i-2o. Cascading of up to 8 devices is possible on the input and output (I/O extension for PLC systems) and 2x 64 analog + 64 digital values can be transmitted with a fixed rate of 1 ms.
Two VME systems can be coupled in peerto-peer mode. On the 2nd diagnostic output parallel measuring with ibaPDA is possible. The update rate can be adjusted between 50 µs and 1.4 ms.
This mode provides the highest flexibility for data exchange with ibaPDA, since transmission rate, size and formatting of data can freely be set. For small amounts of data the cycle time can be faster, up to 25 µs with 65 bytes. The maximum amount of data is 4060 bytes at 1.4 ms.
Moreover, with 32Mbit Flex, it is possible to connect up to 15 devices in a ring topology.
Supported VME systems and modes
The following modes of VME access are supported:
- Addressing modes A24, A32, A40, A64 with data formats 8/16/32 bit (D08/D16/D32/MD32)
- 8/16/32/64 block transfer modes (BLT/MBLT)

Acquire and analyze data
ibaPDA and ibaAnalyzer are the essential tools to acquire and analyze data.
