I am working on a project to read data from a wide range of machinery and equipment used on commercial maritime vessels and similar. Does anyone know of a library of Modbus specifications, ordered by equipment make and model?

 

I doubt it. In 15 years of hanging around this forum no one has ever mentioned any such compilation. It’s hard enough to obtain communications specs for any given device or even worse, determining how to determine whether any specific device has Modbus, given that Modbus is frequently an option. The comm port could be Ethernet/IP or DF-1 or DNP3 or Profibus or proprietary. Good luck assembling a database.

 

Thanks David_2, I was afraid of that!
