Publish as PLC

How to connect (TRACE, RSLinx...)

Turn on Publish as PLC (the simulator must be open; press Run to move the logic).
In TRACE: Configuration → PLC IP = the address shown here (with :port when it is not 44818), then add or browse tags (browse lists every simulated tag).
Any tool that reads a Logix controller by IP works (pylogix, an RSLinx Ethernet device at that address, OPC/DDE readers).

Limits: Studio 5000 / RSLogix cannot go online or download to it; only this PC can reach it. A write from a tool to a tag the logic drives acts as a force.

Forced only Written by the logic Compact rows

Rungs run top to bottom once per scan. Inputs are tags the logic never writes: click a 0/1 to flip it or type a value. Changing a tag the logic writes forces it (🔒) until released. Timers advance by the scan time. Click a tag name on the diagram to toggle that bit. This is a logic simulation, not a PLC emulator.
