913 Broadcast index (BROADCAST INDEX)
Value
0 - 32767
Function
The broadcast index can be used to divide the
VLTs into multicast groups, since only the VLTs with
the same broadcast index as the master will read
the broadcast telegram. The same function can be
achieved with the help of the SAP numbers in pa-
rameter 806.
Broadcast/multicast is only possible if FMS
has been selected in parameter 806.
During an update of parameter 800 or
during the next turn-on procedure, the parameter
913 changes too.
914 Broadcast offset (BROADCAST OFFSET)
Value
0 - 244 bytes
0
Function
The broadcast telegram Information Report (IR)
may contain PPOs of several VLTs. Parameter 914
indicates to the VLT where to fetch the PPO from
the information report.
Broadcast/multicast is only possible if FMS
has been selected in parameter 806.
Description of the selection
During the selection of the number of bytes, the
PPO will be displaced by the header (3 bytes) of
the IR (see page 53). 0 indicates that the PPO will
be arranged in the IR from byte 4 on. Several VLTs
may have the same offset if they are to use the
same PPO. The adjustment of the offset depends
on the PPO length which, in turn, is determined by
the selection of the PPO type in parameter 904.
During an update of parameter 800 or
during the next turn-on procedure, the para-
meter 913 changes too.

Subindex 1
Subindex 2
Subindex 3
Subindex 4
Subindex 5
Subindex 6
Subindex 7
Subindex 8
Function
Different parameters may be assigned to the PCD
1-8 of the PPOs (the number of the PCD depends
on the PPO type). The values in PCD 1-8 are writ-
ten to the selected parameters in the form of data
values.
Control panel read only (Read only); write access
through PROFIBUS or standard RS485.
Description of the selection
The sequence of the subindices corresponds to
the sequence of the PCD in the PPO, i.e. subindex
1 ≈ PCD 1, subindex 2 ≈ PCD 2 etc. Each subindex
may contain the number of any VLT parameter.
However, only 2-byte values (bytes with the lowest
weight) can be written to parameters with 4-byte
data values, since 1 PCD consists of only 2 bytes.

Function
Various parameters may be assigned to PCD 1-8
of the PPOs (the number of the PCDs depends on
the PPO type). PCD 1-8 contain the current data
values of the selected parameters.
