Debugging Ladder Logic
To allow debugging of ladder logic, it is possible to view the state of the various ladder blocks and the
contents of registers. This is accessed from the menu Ladder, Debug. Blocks that are logically true are
shown in red. Debug simply reads all the data values from the RTU and displays all the current states and
values in the ladder. Debug does not sequentially step through the ladder performing one rung, reading the
data then performing the next rung and reading the data etc. Debug simply shows the current value of each
address after the complete ladder has been processed. Note: registers can be viewed in unsigned or
hexadecimal format. Please see View, Local Registers for details.
