Does M340 PLC support Transparent Device Access (TDA) functionality.

Transparent Device Access (TDA) functionality means that clients that run Unity Pro (and that are connected to a USB, Ethernet, or Modbus terminal port of a communications module) can access or download applications to devices on distributed control networks. This functionality is supported by M340 range. The reverse, however, is not true. In other words, a Unity Pro PC connected to the CPU’s Modbus port can access devices on other core networks, but those remote devices can not access other devices on different networks through the PLC station. For TDA following communication scenarios are possible:
  • Ethernet port on the BMX P34 20x0x CPUs to the BMX NOE 01x0 Ethernet modules
  • BMX NOE 01x0 Ethernet modules to the Ethernet port on the BMX P34 20x0x CPUs
  • USB port on the BMX P34 20x0x CPUs to the Ethernet port on the BMX P34 20x0x CPUs
  • USB port on the BMX P34 20x0x CPUs to the BMX NOE 01x0 Ethernet modules
  • Modbus port on the BMX P34 2020 CPU to the Ethernet port on the BMX P34 20x0x CPUs
  • Modbus port on the BMX P34 2020 CPU to the BMX NOE 01x0 Ethernet modules
