ex_modbus_slave and modbus poll
PostPosted: Tue Nov 05, 2013 7:48 pm     Reply with quote
Modbus poll software sending package data and pic receving this info, and pic tx pin sending response message package. Pic rx and tx side modbus protocol working correctly. But I couldn't read this data, pc side RO pin of max487 and modbus poll terminal rx info.

Is it timing problem ? Please help me.

Modbus poll works on the PC side... so what exactly is it that you are trying to do?
