Standard IO-Link Master network block as compared to a dedicated RFID IO-Link Master BIS V
We can do the application using either or both even on the same network at the same time.
If we are exchanging a few bytes at a station, then a standard IO-Link Master block will do well but if we have a large data exchange at a station then the dedicated RFID BIS V is a better solution.
A mixed system is sometimes the best solution.
The points to be noted are :
1. The r/w heads are different for both.
In the case of the standard IO-Link Master block you need to order an IO-Link RFID head since it connects to an IO-Link port.
For the dedicated RFID IO-Link Master you need to order any BIS V compatible head. This head connects to the any of the 4 dedicated ports on the BIS V and not to the IO-Link port of the BIS V.
2 . The speed of data exchange is not the same.
The IO-Link RFID head connected to the standard IO-Link Master block can have a maximum buffer size of 32 bytes per port in IO-Link 1.1 and that determines its speed of data exchange. Furthermore, there may be other components on the other IO-Link ports that also need to communicate. This can slow down the process.
The dedicated RFID BIS V Master has a large buffer size of 128 bytes per port and not many other connected devices since it has just one other available IO-Link port. This is therefore much faster.
Additionally, using Balluff High Speed High Memory we can achieve even faster data exchange using BIS V.
3. The RFID over the standard IO-Link Master block is only possible with HF.
The dedicated RFID BIS V IO-Link Master can be selected with multi-frequency. This can work across LF, HF and UHF. Each head can work on a different frequency simultaneously.
4. The cable length between the r/w head and the standard IO-Link Master block can be up to 20m.
The cable length in the case of the dedicated RFID IO-Link Master can be up to 50m.
