Snap-in I/O Expansion Modules Hardware Configuration
44 VisiLogic: Getting Started
High-Speed Counter: Reload
Reload enables you to immediately load 0 into a high-speed counter when
the counter value reaches a target value. Note that you cannot set the Reload
input to Frequency Measurement.
Stepper via High-speed Output (V570/V1040 only)
If you are using a V570 or V1040 with any model Snap-in I/O module,
VisiLogic 7.00 or higher and the OS released with that version, you can use
specific high-speed outputs to control stepper motors.
Note that any acceleration and deceleration that is needed to arrive at Target
safely and accurately must be implemented in your Ladder application.
Configuring the HSO
1. Click the Output line and select High Speed Outputs (Step Control).
2. The Select Operand and Address dialog box appears five successive times,
