Hi All,
I'm reading from a Modbus slave some address from a Shore power converter (SCP). The master is a Schneider Electric Combo (PLC+OP). When I'm connecting the first time the modbus cable (both system are powered on) I receive the code error 04H and I don't understand the real reason of this error.
The writing area is from 0x00 to 0x10, and reading area is from 0x1000 to 0x1100. I simulate with a modbus slave software the whore area from 0x00 to 0x1100, and no error appeared. The explanation of the error is "slave not ready" but I don't recognize the reason of this error.
has someone met this problem?
Thanks a lot
Stefano
