There are some MODBUS/TCP slave implementations around in this world with a limitation to serve only one concurrent master. Multiple masters accessing such a slave implementation causes all kind of havoc, from aborted TCP connections to packet loss and transmission errors. Modbusmplex is a MODBUS multiplexer that provides a way to work around such a limitation by multiplexing multiple MODBUS/TCP master connections into one MODBUS/TCP connection towards a slave. ...

...HMI is based on Qt library. Different technologies (EiC, GigaBASE, FastDB, ORTE) have been integrated. Supported drivers: OPC DA 2.05a, AE 1.10, HDA 1.20, XML DA 1.0, OPC UA 1.03, DNP 3.0, Modbus TCP/RTU, MQTT 3.1.1/Sparkplug B, IEC 60870-5-101/103/104, IEC 62056 DLMS/COSEM, IEC 61850, M-BUS, SNMP, Ethernet/IP, FINS/TCP.

Free ladder & sequential (grafcet) languages as used on many PLC for programming automation process. Ladder language allows to realize programs on PLC in an electric way. GTK graphical interface to edit/simulate. Modbus protocol for SCADA connexion and remote Inputs/Outputs modules. Logs events available. Can run on embedded targets for real usages (without GTK interface), as Arietta, RaspberryPi, ... Xenomai support for real-time.

A Small SCADA system for Linux. Not really for the casual user, rather, for developers like myself.

A Disk Scheduling Simulator tool. With an intuitive GUI interface and command line functionality. Built using both VC and VB. Currently supports SSTF,LOOK,CLOOK,SCAN and CSCAN algorithms. Rotational latency is also optionally supported.

Remote industrial terminal indicator to the control of Modbus-RTU on Atmega128. Publication of "MODBUS on a leash. Remote industrial indicator. - Radiolybitel, Minsk, 2009, № 7, p.46" (series of articles http://radioliga.com). Project for IAR.

TxEngine is an embedded controller engine designed to allow one to make supervision & control program that fit in embedded systems. Include a modular design with native support for Modbus RTU, timers, threads, linked lists

Ccide reads a source program, in one of several programming languages, expands all embedded decision tables, and generates the new, expanded source. Ccidew processes C language programs directly. The script, ccide, uses ccidew and m4, to process BASIC, JAVA, CC, C++, BASH, QB, VB, and EX(euphoria), source files containing embedded decision tables. Ccide checks all conditions once and only once, avoiding side effects. Ccide checks tables for conflicts and other errors. Input example: //DECISION_TABLE: // 1 3 2 2 | light == $$ /* 1=red, 2= yellow, 3=green. */ // N - - - | speed == STOPPED // - - Y - | speed == SLOW // - N - Y | speed == FAST // ______|___________________ // X - X - | Stop(); // - - - X | SlowDown(); // - X - - | SpeedUp(); //END_TABLE:

"Yet Another Modbus Library" - Functions to handle Modbus/RTU using C and termios. The library behaves as a Modbus master.
