This is a dynamic explicit Class Object. With this Class object any drive parameter with a MEMOBUS/Modbus address greater
than 0x00FF can be accessed. The mapping of Class Object instance/attribute to MEMOBUS/Modbus address is as follows.
Given a typical MEMOBUS/Modbus Address of 0xXXYY
The EtherNet/IP Instance value is equal to XX
The EtherNet/IP Attribute value is equal to YY
As an example, to access parameter b5-12 (MEMOBUS/Modbus Address =0x01B0)
Class Object is 100 (0x64) (Always for this Class Object)
Instance = 0x01
Attribute = 0xB0

Storing Changed Parameters
Writing a zero to 0x0900 (Enter) stores changed parameters to the non-volatile memory of the drive. Writing a 0 to 0x0910
(Accept) allows the drive to use the changed parameters. Reading Enter Command 0x0900 or Accept Command 0x910 will
always return a value of 0x0001.
Performing a RAM-ENTER to Store Register Data
Parameter H5-11 is used to decide whether a RAM-ENTER will be done on the writes to registers in the drive. If H5-11 = 1
(default), the option will issue the RAM-ENTER with the parameter writes. If H5-11 = 0, no RAM-ENTER is issued and an
ENTER command must be explicitly sent by the user for the parameter to be activated after a write.
Explicit writes to RAM-ENTER (0x910) and ROM-ENTER (0x900) are handled as special cases. If a user writes a 0 to RAM-
ENTER or ROM-ENTER, the command will be executed in the drive. If a user writes a 1 to those registers, the command will
not be executed but returns a success to the explicit write on the network. Writing a value other than 0 or 1 will result in an
error response of Invalid Attribute Value on the network.
Note:
Performing the RAM-ENTER increases the processing time of the writes and increases the response time to explicit writes.
