Chapter 10 – Transponder Programming
10.3.1.2 Structure of the Telegram (Antenna -> Host / if Transponder is not
programmed)
This telegram type is sent once if the transponder has not been programmed.
1.
ASCII telegram with fixed start character, 4 bytes of data and a checksum.
2.
Binary telegram with fixed start character, 2 bytes of data and a checksum.
10.3.2 HG G-71451: Programming via Profibus Telegrams
For this type of programming, ST 1 must be connected to supply voltage and the
Profibus interface to a host. The telegrams of the Profibus interface (see chapter 6
on page 32) can then be used to program a transponder positioned under the anten
-
na (see Figure 30 on page 61).
The programming process is initiated by a rising edge of the PROG bit, i. e. the tran
-
sponder code to be programmed should first be transmitted with PROG=0. Then the
same transponder code with PROG=1. This triggers the programming process
which takes approx. 100 ms. The new code is then read immediately and is available
in the input bytes.
10.3.3 HG G-71453: Programming via CANopen® Telegrams
For this type of programming, ST 1 must be connected to supply voltage and the
CANopen® interface to a host. The SDO telegrams of the CAN interface (see chapter
7 on page 35) can then be used to program a transponder positioned under the an
-
tenna (see Figure 30 on page 61). Sub-index 1 of the object with index 0x2000 is
used for this (see Table 55 on page 44).
10.3.4 HG G-71455: Programming via Profinet Telegrams
For this type of programming ST1 must be connected to supply voltage and the
Profinet interface to a host. The telegrams of the Profinet interface (see chapter 8 on
page 47) can be used to program a transponder positioned under the antenna. The
level for the transponder to be programmed should be between 200 and 500.
