that particular bit will be passed through when written.
Each additional group of 32 User Bits that are added, a new Mask parameter will appear for that group. Mask 0 will control the mask for User Bits 0 through 31. Mask 1 will control the mask for Bits 32 through 63. This sequence repeats for each additional 32 bits that is added.
To configure the mask in a user program, the parameter named BitRegisiter.#.ValueMask is written to. The mask can be written to using Hexadecimal based values or decimal based values. To write a hexadecimal value to the parameter, the hex value must be preceded with the characters "0x". To write a decimal value to the parameter, normal notation is used. For examples of writing the Mask to a value in a program, see below.
For example: BitRegister.0.ValueMask = 0xFFFF0000
This example writes a 1 into all bits of the upper sixteen bits, and 0 into each of the lower sixteen bits using hexadecimal value. To write the same value using decimal notation, the following instruction would be used.
For example: BitRegister.0.ValueMask = 4294901760
This instruction would also write a 1 into each of the upper sixteen bits, and a 0 into each of the lower sixteen bits.

7.4.1 Assignments View
External control capability is provided through the use of assignments to the sources (SP Inputs,
Assignments provide a mechanism for the user to define the internal and external dynamic control structure to separate complex motion profiles. These functions directly correspond to any input or output line on the drive or option modules. External controllers, such as a PLC or other motion controllers, may be connected to affect or monitor the device's operation.
The Unidrive SP is equipped with up to six input lines (three can be configured as Input or Output) and up to five output lines (three can be configured as Input or Output and two are Relay outputs). The
The SP drive's input and output lines can be accessed through the two removable
All inputs and outputs are configured as sourcing and are designed to operate from a +10 to 30 VDC power source. The user is responsible for limiting the output current to less than 10 mA or less for each digital output.
Assignments View
The Assignments View is used to tie a source to a
destination. Destinations are found on the right side of the Assignments view, and are functions that need to be triggered, such as Index Initiates, Program Initiates, Jog Initiates and so on. Sources are located on the left side of the Assignment view and reflect the status of events that occur in the drive. These events are based on drive activity. Figure 87 shows an example of the Assignments view.
Figure 87: Assignments View
Sources and Destinations are put into groups based on functionality. By expanding individual groups, you will see the individual Sources or Destinations.
For example, if you expand the Inputs source group, you will see SP I/O, SP Inputs, EZ Motion Inputs, and I/O Plus I/O if a module is used. You can use these Source events to trigger certain actions (or destinations) on the right side of the view.
To make an assignment in the
Creating An Assignment
Various methods can be used to assign a Source (such as SPInput.4) to a Destination, such as Index.0.Initiate.
Drag and Drop Method
First, position the mouse pointer over the Source on the left that is to be assigned to a Destination on the right. Press and hold the left mouse button down, drag the Source until the mouse pointer is positioned over the desired Destination and release the left mouse button.
Once the mouse button is release, the assignment is created. The view will update to show that the assignment is created. In the Sources side, the "Assigned To" column will show which Destination the Source is assigned to. In the Destinations side, the "Set From" column will show
