Modbus request to all slaves
How can we send a request to all slaves with address = 0 ?
MBConnect librairies doesn't accept this address.
Working on AC800M / PM864.
What kind of request would you like to send?
The thing is that in standard MODBUS RTU address 0 is reserved for broadcast messages and write only, with no confirmation or response (for obvious reasons).
Depending on what kind of request You would like to send using zero address is either impossible or just not the best idea.
Hope this helps,
