♦ The "tens digit" of the connector is used to distinguish between a 16-
bit process data item (e.g. 3002) and a 32-bit process data item (e.g.
3032).
♦ If a process data item is transferred as a 16-bit quantity, assign the
required PZDi-relevant connector for a 16-bit process data item to the
selector switch (see "Process data linkage"). (Example: If a 16-bit
process data item is assigned to PZD2, the relevant connector is
3002).
♦ If a process data item is transferred as a 32-bit process data item,
assign the required PZDi-relevant connector for a 32-bit process data
item to the selector switch (see "Process data interconnection"). For
this, use the connector of the least-significant PZDi (Example: If a 32-
bit process data item is assigned to PZD2 + PZD3, the relevant
connector is 3032)
♦ The first word (associated connector : 3001 or the binectors 3100 to
3115) of the received process data is always assigned to control word
1 (STW1).
♦ The second word is always assigned to the main setpoint (HSW).
♦ If the main setpoint is transferred as a 32-bit process data item, it is
also assigned to word 3. In this case, the most-significant part of the
main setpoint is transferred in word 2 and the least-significant part is
transferred in word 3.
♦ If a control word 2 (STW2) is transferred, the fourth word (relevant
connector = 3004 or binectors 3400 to 3415) is always assigned to
STW2.
In PPO types 1 and 3, the PZD part only consists of two words. Here,
only control word 1 and the main setpoint (as 16-bit value) can be linked
up to the dual-port RAM interface.
♦ The connector for the setpoint channel is always a 4-digit one. The
connectors assigned to the process data (PZD1 to PZD10) are shown
in the function diagram of the relevant CU board.
The connectors are entered at the PMU as 4-digits values (e.g. 3001).
When parameterization is done via the PROFIBUS-DP, the connector
is entered via the bus and also via the PMU (e.g. connector 3001 is
transferred as 3001
Process data interconnection of the setpoint channel can also be carried
out via the PROFIBUS-DP if P053 has previously been set to an uneven
value.
Please bear in mind that control word 1 (STW1) has the value 0 during
the parameterization phase (process data interconnection)!
