Programming and Boolean Operations

Program Representation
Previous page	Next page

All PLCs in the SIMATIC S5 range employ the STEP 5 programming language. The PG605 programming panel uses only the Statement List (STL) method of representation, but program instructions can also be represented using a Control System Flowchart (CSF) or a Ladder Diagram (LAD).
