9-9 Monitoring-related Objects
These objects are used for the monitoring setting.
Sets the object for monitoring. You can monitor any object by mapping the monitor data to a TxPDO.
 
• Sets the object for monitoring.
• Set the index in upper two bytes and the subindex in lower two bytes.
 Description of Set Values
 
• Gives the object value set in Target Object.
• The given value is always four bytes. If the size of the set object is less than four bytes, the data size 
will be extended to four bytes by the sign extension. If the size of the set object is four bytes or more, 
lower four bytes of the object will be given.
Precautions for Correct Use
Objects whose data type is BOOL, U, or INT can be set in Target Object. Do not set objects 
whose data type is VS or OS.
