I am assuming that you have the above equipment.
This is either using Modbus ASCII or Modbus RTU. These are both serial communications but can be confusing because the Shark has a RJ45 connector.(Modbus TCP)
Here is a link to tell the difference:

This site has some good information on the Modbus protocol:

It would help to know what exact models of equipment you are working on. Please also include what you have programmed (parameters) so far and what result you are getting. This will help in assisting you.

Regards,
