Yes and no. FANUC is aggressively pushing the (a web-based, HTML5 editor) for their newest FANUC 0i-F Plus and 30i-B Plus controls. However, there are over 2.5 million FANUC CNC units in the field running legacy PMCs (PMC-L, PMC-RB, PMC-N).
The 2021 version introduced faster indexed searching. You can now find all instances of a specific R register across 10,000+ ladder rungs in under two seconds.
Safety logic design saw significant updates. Ladder III provides native blocks to map and validate Dual Check Safety (DCS) I/O. The software ensures that safety-critical inputs and outputs are mirrored correctly across two independent microprocessors, expediting compliance verification during machine commissioning.

Cells and paths change color (typically turning green) to indicate an active high signal state.
View live I/O states and trace logic execution directly on a running machine. Yes and no
Use an Ethernet crossover cable (or switch) from your laptop to the CNC’s Ethernet port (CD38A connector on the main board). Set your laptop IP to 192.168.1.100 and the CNC to 192.168.1.101 .
Output signals sent from the PMC side to control the CNC behavior (e.g., Feed Hold, Axis Interlock). The 2021 version introduced faster indexed searching
