Inputs
Identifier/data type Information/possible settings
bExecute
BOOL
Activates a write request.
FALSETRUE If the cycle time (dwCycleTime) = "0 ms" or the dwCycleTime input is
not assigned:
Write the parameter addressed via the inputs dwCode, dwSubcode,
dwComChannel and dwTargetAddress once
with the value of the
data input which has been selected via dwDataTyp.
If cycle time (dwCycleTime) > "0 ms":
Write the parameter addressed via the inputs dwCode, dwSubcode,
dwComChannel and dwTargetAddress cyclically
with the value of the
data input which has been selected via dwDataTyp.
TRUEFALSE Deactivate cyclic writing again.
dnData
DINT
Parameter value to be written
• The data input and thus the data type of the code to be written is selected via the
dwDataTyp input.

CANopen index (0x0 ... 0xFFFF)
dwSubcode
DWORD
Subcode (0 ... 255)
dwComChannel
DWORD
Interface
• Up to and including controller software version V07, only the selection "1" (own
device) is supported.
1Own device
2 CAN on-board
3CAN module
dwTargetAddress
DWORD
This input does not have any function.
dwTimeOut

Time-out (0 ... 10000 [ms])
• Time in which the write request must have been processed.
• If the input is not assigned or if "0 s" is selected, time-out monitoring is deactiva-
