Problem of reading and writing regs more then 255!

[max-davletchin]

I have 350 regs in my project, but if I want to read regs from 255 and higher - arduino freezes, and doesn't recieve any anser messages (for example, with errors or other). But if I try to read reg higher 350, I get answer with error "ILLEGAL DATA ADDRESS". How can I solve this problem?

I am also having the same problem. I'm trying to figure it out by looking at the source code. did you solve it?

File SimpleModbusSlave.cpp, line 119, change "unsigned char index;" to "unsigned int index;"
