Note for commands which trigger actions such as Zero, Reset, etc.
These commands, like the read commands, do not actually require any parame-
ters; only Index and Subindex. But since the SDO syntax always expects a
parameter (Padding Byte, see above) you must also specify a parameter here,
e.g. 0. The Zero command is thus
Write request from the controller to the ClipX (Object Dictionary Write
Request)
Field Data
name type
Index UINT
Subindex USINT
Padding USINT
Byte
Value UDINT
or REAL
(FLOAT)
This will avoid unintentional writing
Use the following sequence:
1. Set index 0x0000 (no operation).
2. Set Subindex and Value.
3. Set desired index.
The ClipX only evaluates the request after the third step.
Response from the ClipX to the write request (Object Dictionary Write
Response)
The value was successfully written if Index and Subindex match the request and
no error bit is set.
ClipX
SDO 0x4410,4,0LF
Index of object to write.
0x0000 (no operation) sets the response to zero.
Subindex of object to write.
No function.
The value of the object. The data type depends on the
object.
