Hey We are a team of Technical Developers and have got expertise in such stuff. Ping me if you are looking for a quick resolution

Provide a clear example of a similar job you have done in the past. Hi, I have implemented modbus protocol for data acquisition system and motor protection system. Proposal: I have gone thru the pdf specification. but there were no questions.

Provide a clear example of a similar job you have done in the past. Interface ro a vending machine MDB protocol invloving also interface circuit development. Payment data is verified on a web site (tcp). Is a cashless payment system. Proposal: It will suggest to use a low level language as C++ to achieve realtime and comm buffers, depending of expected data rates. Maybe if massive project in mind, substitute raspberry for more embeed developed circuit borad.

Provide a clear example of a similar job you have done in the past. Currently doing several apps gathering data from multiple PLCs via RPi & pushing to Azure etc. Can show you in a web meeting. Proposal: We have driver for MQTT both as a subscriber & server & also Modbus slave. Both will work on RPi. Also have the cloud interactions done for data disbursements to other applications from cloud.
