Module Config Block Attributes

Module Config Block Attributes

The following collection of Module Class Attributes are stored in the controller and sent to the module as part of the Configuration Block of the Forward_Open service.
Axis Test Mode Enabled axes do not simulate these drive attributes.

This attribute is a collection of bits used for configuration of an associated CIP Motion device. Each bit is either true or false.
  • 'Verify Power Structure' bit is used to control whether the drive performs an "extended key" check against its Drive Class ID.
  • 'Networked Safety Bit Valid' bit determines if the 'Allow Networked Safety' bit (bit 2) of this attribute is valid and is enforced by the drive.
  • 'Allow Networked Safety' bit determines if the drive is allowed to accept a Propose_TUNID service request from a Safety Controller to establish safety ownership and subsequent safety connections.

Unique ID of the power structure used to verify if the user selected power structure matches that of the drive device.
If power structure varies with the axis instances of a multi-axis drive device then a value of 0 is applied to this attribute and the controller uses the Drive Power Structure Axis ID to verify matching power structure associated with each axis.
