Procedure „transparent“
For the interconnection antenna <—> PLC a transparent protocol can be used. The fol-
lowing settings have to be observed for the data transmission:
-
1 start bit, 8 data bit, parity even, 1 stop bit, Baudrate 9600 Baud (default) or
19200 Baud.
C.1
Data direction antenna -> PLC
In this direction, cyclical antenna data is transmitted. The duration is parameterizea-
ble, it should take an integral part or multiple of the transponder code transmission.
The minimum cycle duration depends upon the telegram length, the Baudrate and the
chosen telegram content.
The data sentence always starts with an „=“-character (hex 0x3d). Then the parame-
ters chosen from the respective menu follow. The telegram is to be quit with an 8 bit
check sum over all characters. This check character is the result of ex-oring all char-
acters. The characters are transmitted without delay.
C.2
Data direction SPS -> antenna
Commands are transmitted into this direction if necessary. Each command must start
with a „=“-character (hex 0x3d). The format of the commands is described in Table 7
„List of system commands“ on page 19. The telegram is to be quit with a 8 bit check
sum (XOR) over all characters. The characters are sent without delay. The characters
must be received within the parameterizeable character delaytime. Otherwise the tel-
egram will be chopped.
Additionally it is possible to set that the positioning pulse is only deallocated after a
transponder has been decoded.
