Quick Start

2.5. Create and Download Ladder Logic

Applications

Software applications can be created and downloaded to the VMM3120
multiplexing module.

The software applications for the VMM3120 can be created with the Vansco
Multiplexing Module Software (VMMS) tool, using ladder logic.

Consult your Parker Vansco Account Representative for information about your
software programming options.
