- People learning PLC ladder logic
- Worth noticing
- The tag editor validates virtual I/O addresses, including byte-and-bit rollover: after %I0.7 comes %I1.0.
Field notes
The workspace includes a tag table for inputs, outputs, and internal bits, with editable symbols, addresses, initial values, and live values. Its address rules distinguish virtual teaching tags from physical CPU limits, and the page explicitly says no controller is connected. The exercise area shows a three-case test suite and notes that results clear after edits, while the examples range from basic contact logic to timers, counters, sequencing, and interlocks.
