402 Calculation Blocks
Equation
The Equation block assigns a value to:
•
a user variable
• an indirect variable
• certain system variables
• a discrete output
• an output group
• a DH-485 variable
• a cam profile point
• an SLC variable
• an SLC indirect variable.
The assigned value can be a constant, or an expression that GML
Commander evaluates to determine the assigned value.
The Equation block resides on the Main Palette.
The Equation block presents five different appearances depending upon
your response in the Type box. The options include:
• Configured
• Slave_CAM_position
• Master_CAM_position
• Master_CAM_time
• Indirect_Variable
The steps for configuring each type of equation are set forth below.
Configured
Select Configured in the Type box to assign a value to an Axis System
variable, an AxisLink I/O output or output group, a DH-485 variable, a
General System variable, an SLC variable or a User variable. Make
entries in the following fields:
