- TCP Server and TCP Client which use socket programming with java langhage.
- TCP/UDP between client and server
- This server / ModBus slave simulates equipment communicating with the ModBus protocol on a TCP / IP as a controller for example. It responds to requests from a master / client. I used ModScan32 and a monitoring software that I developed in my company for testing. Some details: - 4 tables of data are scaled to 200 items each (constant chosen arbitrarily) and values of each item (bit / register) can be modified in the cell corresponding - Responses to requests functions 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x10, 0x0F - Return management of exceptions ModBus started but complete - Visual refresh table data after a write request to complete The software is not finalized and has been tested only in certain configurations, it must contain some bugs. If you detect inconsistencies vis-à-vis the protocol, please let me know (I have some issues that differ among the PDF and found the software testing as ModScan32). Development in Visual Studio.
