PLC Equivalent Structures
While the TReX-460 does not directly support several common structures found in PLC
programming software, equivalent functionality can be achieved using the following
configurations:
Nested
Branches
The TReX does not directly support nested branching, however, equivalent functionality can
be achieved by evaluating nested branches beforehand and storing their result using an internal
register bit. In this example, the nested branch evaluating
Input 3 OR Input 4
is replaced with
a preceding rung which evaluates the statement and stores the result in
Register Bit 1
.
Multi-Branch Rungs
The TReX-460 does not directly support the implementation of multiple separate branches on a
single rung. If multiple branches from a single main rung are required, these branches must be
placed on separate rungs like so:
