Each Assembly instance has the following attributes:
Attribute ID Name Data Type
Default value
1 Data Array of Bytes -
2 Size UINT -
Object Connection Manager
The object Connection Manager allocates and manages the internal resources associated with both
I/ O and Explicit Messaging Connections.
Object Parameter
Use of the object Parameter provides a known, public interface to a device's configuration data. There
must be one instance of this object class for each of the device's configurable parameters. The
instances must start at instance one and increment by one with no gaps in the instances.
The implemented instances of object Parameter can be found at the EDS file.
Instance attributes:
Attribute ID Name Data type Default Services
1 Value Variable - Get/Set (*)
2 Link Path Size USINT 7 Get
3 Link Path (**) EPATH - Get
5 Data type USINT - Get
6 Data Size USINT - Get
(*) Parameter value can be set if the instance belongs to a R/W variable.
(**) Link path: CIP path to the object from where this parameter's value is retrieved. The packed PATH of the
parameter object has the following structure:
Class Segment Class ID Instance Segment Instance ID 1 Instance ID 2 Attribute Segment Attribute ID
0x20 0x0F 0x25

0x30 0x01
In the case of the Ethernet/IP board for SD750 drives, object Parameter will have as many instances
implemented as configuration and visualization parameters exist in the drive. They will be organized
consecutively, and the first instance will be number 1. Refer to the Software and Programming Manual
of the SD750 drive to consult details about each parameter, as well as their Modbus address.
