Circuit Diagrams and Ladder Programs
In preparation for creating ladder programs, this section describes the
relationship between relay circuits and ladder programs.
2-1-1
Ladder Programs
The ZEN uses ladder programs that appear like relay circuit
diagrams.

Basic Configuration of the ZEN Ladder Programs
The ZEN can execute up to 96 lines of programming, with 3 inputs
and 1 output per line. Outputs can be specified at the right ends of
lines only. Inputs cannot be specified after outputs.
The ladder program inputs and outputs are displayed on the ZEN
Support Software screen as shown below.
