Presentation
BMX P34 2020 and BMX P34 20302 standard format Modicon M340 processors
with integrated Ethernet port occupy a single slot marked “00” in the rack on the
Modicon M340 platform.
Description
The front panel of BMX P34 2020/20302 Modicon M340 processors features:
A safety screw for locking the module in a slot in the rack.
A display block with 8 LEDs, including 3 relating to the Ethernet port:
ETH ACT LED (green): Activity on the Ethernet network
ETH STS LED (green): Ethernet network status
Depending on processor version:
Version 1: ETH 100 LED (green): data rate on the Ethernet network (10 or
100 Mbps)
Version 2 and later: ETH LNK LED (green): Ethernet link status
A mini B USB connector for a programming terminal (or Magelis XBT GT/GK/GTW
HMI terminal).
A slot equipped with its Flash memory card for saving the application and
activating the standard Web server (Transparent Ready class B10).
An RJ45 connector for the connection to the Ethernet network.
Depending on model:
BMX P34 2020 processor: An RJ45 connector for the Modbus serial link or
Character mode link (RS 232C/RS 485, 2-wire, non-isolated)
BMX P34 20302 processor: A 9-way SUB-D connector for the master CANopen
machine and installation bus.
On the rear panel: 2 rotary switches for selecting the IP address using one of
3 assignment methods:
Address set by the position of the two switches
Address set by the application parameters
Address set by the Ethernet network BOOTP server
