How to transmit bits via modbus rtu to the modbus slave program?

I need to learn how to communicate my odnoletniki(beaglebone) with the program modbus slave. I need to get the bits. Use the libmodbus library. The problem is that the data he's sending.

Most likely the equipment with a modbus slave and should not, by itself to send data, because there is "modbus master" which should send the query to a "slave" and even then it will respond to the request.
The equipment is there but to write down any bits, not a word can holidays combined with and to learn from it what data it stores - Darwin commented on March 19th 20 at 09:11
Do not quite understand what you write, it is impossible to send data from equipment to a modbus master? or do not understand how the library works with the equipment libmodbus modbus slave? - karlie25 commented on March 19th 20 at 09:14
Sorry the problem was solved was the problem in the device which the signal was received - Darwin commented on March 19th 20 at 09:17
