Hi,
Could anybody please confirm/deny that the maximum frame size for modbus rtu is: 6 (header) + 250 (data) + 2 (crc) bytes
This is both for queries and responses.
I figured this out from the maximum number of I/Os and registers that can be read/written to for several PLCs.
I did not find any clear statement giving the maximum frame size.
Granted, I didn't look too hard for it...
Thanks
Mario.

The box said it requires Windows 95 or better, so I installed Linux
