Software evolution went from TwidoSuite for compact controllers, through PL7 (for the TSX Micro/Premium), Unity Pro (now EcoStruxure Control Expert) for the Modicon M340, Premium and Quantum, to SoMachine (now EcoStruxure Machine Expert) for the M241/M251 range.

Communication protocols include Modbus RTU/TCP as a native standard, CANOpen for field networks, and Ethernet/IP. Schneider's OPC Server (OFS — OPC Factory Server) enables integration with third-party SCADA systems. Here you will find guides on simulation, communications, and programming with these tools.
