Zero-hardware simulator for 28 industrial protocols — Modbus TCP/S7/OPC UA/BACnet/MQTT & more. Test SCADA, HMI & IoT gateway software without real PLCs. 零硬件仿真28种工业协议设备，测试上位机/SCADA/网关，开箱即用。
A star delta has been computed for 62,678 of 63,382 tracked repositories in this period, and only those can be ranked in it.
A repository missing here has not been measured far enough back yet. That does not mean it did not move.
Star counts measured between 02:27 and 17:17 (BKK).
