Hi, i'm using modbus tcp as server on arduino from this project, is any posibility to change ID number of my server? i can read the same values on different ID's, and i think its little weird

It seems to be a problem. The library has no place to include the slave ID in TCPIP mode. My supervision device requires defining a slave ID and with "1" it does not work. Has anyone had this problem and found a solution?
