10.4 Changing data objects
To view the process data of a device, you must go to its tabs and pull up the
splitter at the bottom. The device must be operational.
To change any object that is assigned to the process data, you must right click
on it in the process data display and force it. The device must be operational.
To view the SDO data of a device, you must go to its tab "CoE". Depending on
the window sizes it works better if push down the splitter of the process data.
The device must be at least pre-operational.
To change any SDO object, you must double click on it in the tab "CoE" and
download it. The device must be at least pre-operational.
The hexadecimal index values and data of objects are written like this:
0x1234
-> Object Index 0x1234
0x1234:87
-> Object Index 0x1234, subindex 0x87
0x1234:87 = 54
-> The object at index 0x1234 and subindex 0x87 is set to 54.
0x1234:87 = 0x54
-> The object at index 0x1234 and subindex 0x87 is set to 0x54 = 84.
Some objects are write-protected, for example the ratings and the inductivity of the
motor, and the serial number. If you try to change them by SDO downloads, you will
get this SDO abort code:
0x08000022 - Data cannot be transferred or stored to the application because of the
present device state.
If you really need to change a write-protected parameter, please contact the
manufacturer of this device.
