16.3.1 Data Direction Antenna –> PLC
Antenna data is transmitted cyclically from the antenna to the PLC. The cycle time
can be parameterized, it must last an integer part – or a multiple of it – of the tran
-
sponder code transmission. The minimum cycle time results from the telegram du
-
ration and thus depends on the baud rate and the selected telegram content.
The data record always starts with an "=" character (hex 0x3d). This is followed by
the parameters selected in the corresponding menu. The telegram is terminated
with an 8 bit check character over all characters (incl. start character). For the check
character, all characters are exclusively processed. The characters are sent without
delay.
16.3.2 Data Direction PLC –> Antenna
Commands are transmitted from the PLC to the antenna as required. Each com
-
mand must start with an "=" character (hex 0x3d). The command format is described
in 9.2.2 „List of System Commands“ on page 38. The telegram must be terminated
with an 8-bit check character over all characters (incl. start character). The charac
-
ters must be received within the parameterizable character delay time. Otherwise
the telegram is discarded.
16.4 Overview of the CANopen® Directory
All objects of the antenna are listed in the CANopen® Object Index. Each entry is a
16-bit index. Sub components are mapped by an 8-bit subindex. RO indicates en
-
tries that are read only.
Communication parameters are marked by a C.
Manufacture parameters are marked by an M.
The object directory is divided into the following sections:
16.4.1 Communication Specific Entries within the Range of 0x1000 to
0x1FFF
