• Also accesses the SEW parameter index.
• Class code: 0F
hex
INFORMATION
Access to an SEW parameter index via the parameter object is complicated and
prone to errors.
Therefore, only use the parameter object in exceptional cases if the EtherNet/IP™
master does not support parameterization via the mechanisms of the register object.

The instances of the parameter object should be used only to access the SEW Para-
meter index when the EtherNet/IP™ master in use does not support the process of at-
taching own data to the services “Get_Attribute_Single” and “Set_Attribute_Single”.
Addressing a SEW parameter index with the parameter object takes place in several
steps:
1. Set the address of the required parameter in the instances 1–4.
2. Access the parameter that is addressed in instances 1–4 using instance 5.
