I'm investigating a machine that uses Modicon M340 controllers, but I have no experience with those models and hope I can get some general advice.
The CPU is a BMX P34 2020, whose prominent features are "1024 discrete I/O, 256 analog I/O, Modbus, and Ethernet", according to the Schneider website.
I've been able to open up the Unity Pro XL software and see that there is an IO Scanning feature for the onboard Ethernet port, but that's where my experience stops.
I'd like to be able to control an Altivar 71 AC drive, and some Turck BL67 analog Input modules (with a BL67 network adapter with Modbus/TCP).
Does the M340 model P34 2020 support such "I/O Scanning" features on its built-in Ethernet port ? Is the protocol ordinary Modbus/TCP, or is there some special Ethernet protocol specific to the M340 family ?
