Setting Up Parameters
User Bits View
User Bits act just like User Variables except that they allow the user to store bit level
parameters rather than 32-bit parameters. The user may customize each User Bit by giving it
a Name and an Initial Value.
parameters rather than 32-bit parameters. The user may customize each User Bit by giving it
a Name and an Initial Value.
The Name for each bit may be up to 12 characters in length, and must start in an alpha
character (non-numeric character). Spaces are not available in the Name for a User Bit,
however the underscore character ("_") may be used.

however the underscore character ("_") may be used.
The Initial Value for each user bit is configured using a checkbox for the specific bit. To make
the Initial Value "On" or "Active", simply enable the checkbox for that bit. The default value
for each User Bit will be "Off" or "Inactive".

User Bits are configured on the User Bits view as shown in Figure below.
User Bits may be accessed in the User Program. Several examples of this are shown below.
Bit.Raise_Table = ON
Wait For Bit.Vacuum_ON = OFF
Wait For Bit.RunPart_A OR Bit.RunPart_B OR Bit.RunPart_C
If (Bit.RunPart_A = ON AND Bit.Vacuum_ON = OFF) Then
Call Program.1
Endif
Bits are turned on by setting them equal to ON, TRUE, YES, SET, or ENABLE (not case
sensitive), and can be deactivated by setting them equal to OFF, FALSE, NO, CLEAR, or
DISABLE. Setting an individual bit equal to 1 or 0 in a user program will cause a red dot
error. The Boolean values listed above must be used.
