Support Questions / Re: Schneider M Seires Modbus TCP/IP

OK... from your comment, "the 'first coil' would be addressed by 00001"

So, "from Modbus perspective", is this the first coil used in the ladder? If I have a coil addressed in the program as %Q0.1, and a following coil addressed as %M0.1, would the Modbus addresses be 00001, and 00002, respectively? My conundrum is how to separate real world output coils from internal coils.

I was able to read and write to the internal %M.x coils using modbus 00001 etc, but couldn't figure out how to address the real world PLC outputs.

Pending your reply, I'll look up the documentation on my PLC next week ,and get you a screen capture of it

Hi, I am working with the new Schneider M series PLC, specifically the M221.

I got Advanced HMI to work well with holding registers, %MW, using Modbus 40000 address

Also got the %M to work with 10000 address.

My question is, how to address the inputs %I, and outputs %Q

Any info is appreciated, thanks
