 "description": "Fieldsim turns your iPhone into a real industrial and IoT protocol test bench — no extra hardware, no lab PC, no separate test tools.\n\nFieldsim isn't a mock-up. Every protocol is implemented against its real wire-level specification and verified against industry-standard reference clients and libraries. Real SCADA software, PLCs, and IoT gateways can connect to your iPhone and talk to it exactly as they would to a real field device.\n\nSimulate 11 real protocols:\n• MQTT — full broker with multi-topic publish/subscribe\n• OPC UA — session/subscription server with a real address space\n• Modbus TCP — coils, discrete inputs, holding & input registers\n• BACnet/IP — Who-Is/I-Am discovery, ReadProperty/WriteProperty\n• DNP3 — link/transport/application layers, Class 0 polling, Direct Operate\n• EtherNet/IP — CIP explicit messaging (Get/Set_Attribute_Single)\n• SNMP v2c — GET/GETNEXT/SET plus trap notifications\n• AMQP 0-9-1 — full exchange/queue/consumer message broker\n• CoAP — RFC 7252 with the Observe extension for live push updates\n• HART-IP — session-managed Pass-Through with Universal Commands\n• LoRaWAN — a real Network Server speaking the Semtech UDP protocol, with AES-128/CMAC frame encryption and authentication\n\nEvery protocol, both directions. Each simulator supports multiple simultaneous tags, points, or objects — build out a small virtual plant, not just one sensor. And every protocol also has a matching built-in client on the Client tab, so you can test your simulator (or any other real device on your network) without installing a second app or opening a terminal.\n\nBuilt for real testing, not demos:\n• Live, scrollable activity logs for every simulator and client\n• Save and reuse connection presets per protocol — host, port, credentials, and protocol-specific settings\n• Automatic detection of your iPhone's network address, so external clients always know where to connect\n• Configurable value patterns (random, sine wave, ramp, static) for realistic simulated data\n\nWho it's for:\nAutomation and controls engineers validating SCADA/HMI integrations, QA teams testing IoT gateways and protocol converters, product developers building device firmware against real-world protocols, and students or instructors learning how industrial protocols actually work on the wire.\n\nFieldsim is iOS-native, built entirely on Apple's Network framework — fast, lightweight, and works over Wi-Fi with any device on the same network.",
