903 Write PPO type 4 (WRITE PPO TYPE 4)
Value
12 bytes [0]
No control panel access
Function
When PPO communication with FMS is used, the
PPO must be sent as a data value with the help of
a write instruction to one of the parameters 900-
903 or 905, depending on the type of PPO. A de-
scription of the PPO types can be found on
page 13.
904 PPO selection for DP (PPO TYPE SELECT)
Value
✭ PPO type 1 (PPO TYPE 1) 900
PPO type 2 (PPO TYPE 2) 901
PPO type 3 (PPO TYPE 3) 902
PPO type 4 (PPO TYPE 4) 903
PPO type 5 (PPO TYPE 5) 905
Function
The PPO type to be used must be selected if DP
has been selected in parameter 800. The function
is valid for read and write functions, i.e. the same
PPO type must be used for both read and write.
In the case of an FMS communication, parameter
904 indicates the PPO type last used for write.
Description of the selection
– PPO type 1: 12 byte PPO with parameter chan-
nel for writing and reading of parameters and
4 bytes process data (control/status word and
reference value/output frequency actual value).
PPO type 2: 20 byte PPO, like PPO type 1 with
eight additional bytes of selectable process
data.
– PPO type 3: 4 byte process data (control/status
word and reference value/output frequency ac-
tual value).
– PPO type 4: 12 byte process data, like the pro-
cess data portion of PPO type 2.
– PPO type 5: 28 bytes, like PPO type 2 with eight
additional bytes of selectable process data.
A comprehensive description of the PPO types can
be found on page 13.
During the update of parameter 800 or
during the next turn-on procedure, the para-
meter 904 changes too.
907 Read PPO type 1 (READ PPO TYPE 1)
Value
Read only, 12 bytes [0]
No control panel access
908 Read PPO type 2 (READ PPO TYPE 2)
Value
Read only, 20 bytes [0]
No control panel access
909 Read PPO type 3 (READ PPO TYPE 3)
Value
Read only, 4 bytes [0]
No control panel access
910 Read PPO type 4 (READ PPO TYPE 4)
Value
Read only, 12 bytes [0]
No control panel access
Function
When PPO communication with FMS is used, the
PPO must be read as a data value with the help of
a read instruction from one of the parameters 907-
910, depending on the type of PPO. A description
of the PPO types can be found on page 13.
911 PPO type for FMS read (PPO READ TYPE)
Value
✭ PPO type 1 (PPO TYPE 1) 907
PPO type 2 (PPO TYPE 2) 908
PPO type 3 (PPO TYPE 3) 909
PPO type 4 (PPO TYPE 4) 910
Function
When FMS communication is used, parameter 911
indicates the PPO type last used for read (parame-
ter 800 = FMS). The parameter is without function if
DP or DP with 1 byte PPO has been selected.
