Instance attribute “RefFromNet”
This attribute reveals whether the torque or speed reference
is local or from the network. If the reference is local, the
value of the attribute is 0. If the reference is from the
network, then the value of the attribute is 1.
9.2.3 Vendor specific objects
9.2.3.1 Vendor parameters object, class 0xA0
The Vendor Parameters Object is a vendor-specific object
which allows the user to access any application parameter
from the drive.

9.2.3.1.1. Instance attributes
Instance attribute “Parameter Value”
If you want to read the value of a drive parameter, for example
,“Motor control mode” ID600
d
, set the instance attribute to
value 600
d
and the instance number to 1 to the request. The
data type of the parameter value can be 8, 16 or 32 bits.
The OPTE9 also supports an old method from the OPTCQ
option board of reading/writing ID values when the PLC
supports only 8 bit instance attributes. This method is bit
more complex.
In this mode, set the instance number to high octet of the
ID, and the instance attribute as low octet of the ID. For
example, if you want to read the value of ID 2291
d
(08F3
h
),
the Get_Attribute_Single service request is targeted at the
Vendor Parameters class, instance 08
h
and attribute F3
h
.
9.2.3.1.2. Services
Instance service “Get_Attribute_Single”
When invoked in an instance, the parameter ID to be fetched
from the drive is calculated, then the read operation is started
and once available, a response is provided to the master.
The format of the message is as follows:
Table 116.
Field Data
Service Code 0Eh
Class Code A0h
Instance Number 01h
Attribute ID XXXXh
The old format of the message is as follows (OPTCQ
option board):
Table 117.
Field Data
Service Code 0Eh
Class Code A0h
Instance Number YYh
Attribute ID XXh
Instance service “Set_Attribute_Single”
When invoked in an instance, the parameter ID to be
modified in the drive is calculated. The data type, write
permission etc. are verified before the write operation is
started. When the operation finishes, or if an error occurs,
an appropriate response is provided to the master.
The format of the message is as follows:
