Yaskawa Monitor/Control Object - 125 (Class 0x7D)
Services Supported
This is a dynamic explicit Class Object. With this Class object any parameter with a MEMOBUS/Modbus address less
than 0x0100 can be accessed. This class is similar to the Drive Parameters Object Class 100, except that since the most
significant byte of MEMOBUS/Modbus address is always zero, the instance in this class remains at "1".
Given a typical MEMOBUS/Modbus Address 0f 0x00YY
The DeviceNet Instance value is equal to 0x01
The DeviceNet Attribute value is equal to YY
As an example, to access Drive Status (MEMOBUS/Modbus Address = 0x002C)
Class Object is 125 (0x7D) (Always for this Class Object)
Instance = 0x01
Attribute = 0x2C
Attributes Supported
Note:
Attempting to set a read-only parameter results in a DeviceNet error code of 0x0E, Attribute Not Settable.
Note:
Attempting to access an invalid parameter results in a DeviceNet error code of 0x09, Invalid Attribute Value
Note:
Refer to the MEMOBUS/Modbus Data Table in Appendix C of the technical Manual for the drive the DeviceNet Option is
connected to for a list of monitor data using the MEMOBUS/Modbus message area.
