Communication station configuration
...
- Communication protocol "ID-Innovations RFID ASCII Protocol".
- Any address parameters are not required. Only one ID-Innovations sensor may be connected to the line. Because of a random module sending only in the moment of card loading, some conflicts could occur on the transmission line.
I/O tag configuration
...
Possible I/O tags: Ci, Co, TxtI.
These three I/O tags must be configured to work properly:
| I/O tag | Address | Meaning |
|---|
| TxtI | 1 | This text input acquires the value of ID read from the RFID card. The ID of the card is a hexadecimal number. |
| Ci | 1 | A cardinal input value incremented with every |
a | new ID published in a text I/O tag. |
| Co | 1 | After the ID published in TxtI is processed, the same value, as is in Ci, must be written into this I/O tag. This handshaking ensures that no information about the received ID will be lost. |
