1 CHAPTER OVERVIEW
This chapter introduces the PSL (Programmable Scheme Logic) Editor, and describes the configuration of the digital
inputs and outputs. It pr
ovides an outline of scheme logic concepts and the PSL Editor. This is followed by details
about allocation of the digital inputs and outputs, which require the use of the PSL Editor. A separate "Settings
Application Software" document is available that gives a comprehensive description of the PSL, but enough
information is provided in this chapter to allow you to allocate the principal digital inputs and outputs.
