PLC Simulator
Practice on a live Modbus TCP plant
Your own private water plant on the internet: a water tank with an inlet valve, a pump, a drain and alarms. Read it and drive it from your own HMI, SCADA or Modbus client, and watch it respond. Load your own register map from a spreadsheet.
The trial needs a free account (email only, no card). The sign-up link brings you straight back here to start it. Or become a founding member: lifetime access for $97 one-time (limited time), with Pro Library membership for life included.
