Setting the IP address with an NFC-compatible mobile device
•
Activate the NFC antenna by setting mode selector S1 to the middle position (Stop).
•
The desired IP address sections can be written to address bytes 0 – 3 with a suitable NFC app.
Setting the IP address from CODESYS
The "OPAK_RFID" library is available for reading/writing the IP address.
The following code fragment demonstrates writing of the IP address:
// In order to read and write the IP address via CODESYS, the NFC antenna doesn't
// have to be switched on
IF bWriteIP THEN
Address_IP := 16#C0A86479 // 192.168.100.121
NumberOfWiteBytes := ELA_OPAK_RFID.writeToNFC( addr := ELA_OPAK_RFID.IP,
bWriteIP := false;
