4.2.3.2. Multiple Parameters Set_Malt_Parm service
With this service it is possible to write the value of 1 or more (maximumlO) drive or DGFC parameters.
Drive parameters keep their own identifier.
DGFC parameters have their own identifier added with
40000dec
(parameter 1 of DGFC must be accessed as
40001)
Following is an encoding example:
To write the value of parameter
8193dec
and
8194dcc
of the drive and 700dec and
701dec
of the DGFC:
From client to server:
Client

Server
~ ,00000003
where:
01 is the destination MACID
4c is the code of “Set_Mult_Parm” service request
65 is the class to which the service is addressed
00 is the instance to which the service is addressed
8193d is the 1st instance to which the service is addressed (parameter 8193 of the drive)
00000000 is the value of the 1st written parameter. Important: this fieldis always 4 bytes long. The data type
of the written parameter must be. known.
8194dec
is the 2nd instance to which the service is addressed (parameter 8194 of the drive)
00000001 is the value of the 2nd written parameter. Important: this field is always 4 bytes long. The data
type of the written parameter must be known.
40700dec is the 3rd instance to which the service is addressed (parameter 700 of the DGFC)
00000002 is the value of the 3rd written parameter. Important: this field is always 4 bytes long. The data
type of the written parameter must be known.
40701d
is the instance to which the service is addressed (parameter 701 of the DGFC)
00000003 is the value of the 4th written parameter. Important: this field is always 4 bytes long. The data type
of the written parameter must be known.

cc is the code of “Set_Mult_Parm” service response
0000 is the result of the 1st writing operation
0000 is the result of the 2nd writing operation
