To read the attribute #7 (Parameter name) of parameter
700de’
of the DGFC:
From client to server:
Client
->
Server
Ol,Oe,Of,4O7OOdE~,O7
where:
01 is the destination MACID
Oe is the code of “Get_Attribute....Single” service request
Of is the class to which the service is addressed (Parameter class)
40700 is the instance to which the service is addressed (parameter 700. of DGFC)
07 is the attribute to which the service is addressed (attribute: parameter name string)
From server to client:
Client
<-
Server
O0,8e,Oa,20,69,76,61,72,20,30,20,20,20,20
where:
00 is the destination MACID
8e is the code of “Get_AttributeSingle” service response
Oa is the length of the string associated.
20,69,76,61,72,20,30,20,20,20,20 is the ASCII string that identifies the parameter (“ivar 0”)
4.2.2.2. Single Parameter Set Attribute Single service
With this service it is possible to write the value of any drive or DGFC parameters.
Drive parameters keep their own identifier.
DGFC parameters have their own identifier added with
40000dec
(parameter 1 of the DGFC must be accessed as
40001)
Following is an encoding example:
To write the value of parameter
8193dC’
of the drive:
From client to server:
Client
->
Server
where:
01 is the destination MACID
10 is the code of “Set_AttributeSingle” service request
Of is the class to which the service is addressed (Parameter class)
8193dec
is the instance to which the service is addressed (parameter 8193 of the drive)
01 is the attribute to which the service is addressed (attribute: value)
0000 is the value to be written. Important: this field can have any len2th. The length depends on the type of
data of the parameter written. The data type of the parameter to write must be known.
