Have Modbus RTU module, that we need to continuously read ‘value’. C# makes steady 62-64 reads per second. Need source code in C++ that would make the same steady 62-64 reads per second. Have source code for Modbus TCP in C++ that I can provide, though it was not tested. All needs to be source, no involved. Needs to stream consistently. Console, updated once per second with last value read and number of reads per last second.

Planet Paints is a small paint and petrochemical recycling business in Toowoomba, Australia. Recently we acquired several Scadapack 334 units from decommissioned RTU panels and would like to incorporate them into a new plant we are planning to build. The plant is a solvent distillation unit heated with thermal oil which is, in turn, heated by a package diesel burner located outside the hazardous area. Cooling of solvent vapours is achieved in a shell and tube condenser. Water is cooled by a radiator style heat exchanger which is also situated outside the hazardous area. This plant is controlled electromechanically with a rudimentary control panel. The new plant we hope to control via the Scadapack 334 units we have. The systems we want to control are as follows. Thermal oil system...

I will do the hardware side of the system software. Integrations of ST or Microchip company will be used. - Modbus RTU 485 - Modbus TCP/IP - Information transfer will be provided wirelessly using Wireless (Esp8266 HTTP sever, MQTT, Router Mode), and wired using RJ45 connector Port, 10/100 Mbps speed, Modbus / TCP, TCP / IP, UDP, DHCP, Bootp, SNMP, HTTP, CGI, SNTP, SMTP protocols. Maybe later, communication with PROFINET, which can integrate with Siemens, Panasonic and Omron PLCs, can be added. However, this may be V2.

Hello, we looking for a interface project in order to communicate through modbus RTU/RS485 to a UART/ASCII device.
----------- Objective ======= We are looking for candidates with strong competence in Android Native Java and familiarity with Modbus RTU, ASCII, TCP applications. We are looking to build an Android Java based Modbus App chat program that can be configured in Master Mode or Slave mode. See Image attached. Requirements: 1) App is a simple chat program that communicates in Modbus. 2) App can support multiple Modbus protocols, RTU, ASCII or TCP. User can configure which protocol they want to communicate with. 3) App can be configured to work in Master mode or Slave mode. 4) Same app should be able to run two Android Devices to test. Android Device A will be able to run the app in Master Mode. Android Device B will be able to run in Slave mode. 5) App should be written Native ...
Devward needs two separated C libraries for Modbus and BACnet for ESP32 The Modbus library should implement all three available communication types: - ASCII - RTU - TCP Note on the Modbus library: Devward has already implemented Modbus RTU using the ESP-IDF but the problem is that we need a compact Modbus library that includes ASCII, RTU and TCP in one since TCP is not implemented in the ESP-IDF. The BACnet library should implement the following: - BACnet/IP - BACnet/MSTP These two libraries shall be lightweight and optimized as we are already running many things in the ESP32. The developer can use existing libraries to create these two new as long as he/she complies with the two criteria mentioned before and the code is well documented and structured.
The NovaTech RTU communicates with the SEL RTU through DNP3 and does not directly RAISE or LOWER the setpoint. The NovaTech provides the setpoint for the SEL to RAISE and LOWER the actual controller setpoint using the MODBUS coils. The program that is needed requires taking a DNP3 SetPoint value from the NovaTech RTU (this tag does not exist today and must be created on both ends) and initiate a RAISE or LOWER of the MW setpoint by clearing (operClear) and then setting (operSet) the associated MODBUS Coil (CT1LOADRAISE or CT1LOADLOWER). For each of the MODBUS devices, the SEL is the client and the Controllers are the servers. For DNP3, the SEL is the server and the NovaTech is the client. RTAC project file will be provided after project has been awarded to successf...
Write sample code to communicate between C# and Arduino Uno over Modbus RTU. C# is the master, Arduino is the slave communicating over RS485. C# app should use the this library - Need the ability to read and write 8 x bits, 8 x 16uint and 8 x 32uint. Buttons should be used to toggle individual bits, and text boxes used to enter new int vals to send to the Arduino. Scan rate 20Hz(50ms) preferably at a 115200 baud rate. If you have any questions please ask before bidding on the project.

I have 20 Modbus devices (Rs-485) connected to ATC -820 Converter (its just simple RS485-USB converter) using multi hopping. These devices have ID (serial number) 1 to 20 in sequence. Each Device will have 10 parameters (memory locations - holding registers) to read. I have to save data is mySql data base will following table structure with timestamp I want to read data every second from all these Devices using JAVA, multi threading. As I have single device for testing. So as of now Code can be tested on 1 device and can be tested for rest of the devices on site at client end. Support will needed to test it at client end after lock down period is over.

...CONTROL INTERFACE: Designed to control the two-speed fan motor and the electric heater for temperature regulation (two stages). BASIC OPERATION: At start-up, frequency must be tested during 2 seconds using ZCD signal. No operation is allowed till reach an stable frequency inside valid range 40Hz to 70Hz. Switch ON AC power RELAY when all is ok. At this moment the interface waits for MODBUS-RTU commands. Fan speed control: low / fast / stop (2 digital lines). Very important: changes in speed must be synchronized with ZCD input signal. It’s very important to give the maximum priority to any modbus command from master. 20ms is the maximum allowed delay to execute the order. ZCD signal control, corresponding to AC line frequency. Alarm if it’s out of normal rang...
