IO750 - SDO Write
IO750 - SDO Write —
Writes data to local EtherCAT Service Data Ojects
Library
Simulink Real-Time - Speedgoat
Description
This block is used to write the service data objects of the subordinate device. Use the IO750
Setup block to define those objects. On the network side the objects can be read and
written by the EtherCAT main device.
Your model can contain only one SDO Write block for each I/O module in your target
machine. This single block handles all SDO writing accesses of the model to the SDO
dictionary.
Your model must contain one Setup block and one SDO Read block for proper SDO
communication. The SDO Write block is optional.

This block is only supported by MATLAB from R2019b. |
Ports
Inputs
This block has one input port for each SDO defined in the SDO table in the
Setup block whose Access Mode is "write" or
"read-write". The type of the port depends on the property Data Type. The Name of the port
will be assembled with the properties Index,
Sub Index and Name.
If no SDO has Access Mode "write" or
"read-write" then the block will have no input ports.
Outputs
This block does not have any output ports.
Parameters
-
Module ID
This ID defines the link to the corresponding Setup block
-
Sample Time
Defines the base sample time at which this driver block gets its sample hit. This
parameter can also be set to -1 for inherited
sample time. The units are in seconds.
| Caution |
|---|
All blocks that interface with the same I/O module must have identical
sample times. |
-
Retrieve SDO Configuration
Retrieves the SDO configuration from the related Setup block and
updates the input ports.
