7-5 Mitsubishi Communications Manual
The Mitsubishi blender uses a FX-2N processor that communicates with the outside world using
MELSEC FX protocol over Ethernet hardware. It’s Ethernet speed is 10 Mbits/second. The blender must
be purchased from ACS with the Ethernet option. If this was not done at the time of purchase it can be
added afterwards by consulting the factory. The blender has a programmable IP address and subnet mask
that can be programmed from software that is provided by DIGI for the Ethernet module (refer to their
manual).
Ethernet is the standard that we support, but Mitsubishi also supports Profibus and MELSEC Serial
communications. Refer to Mitsubishi for parts and information.
The communications port settings on the PLC are: 19,200 baud; 8 data bits; no parity;1 stop bit; software
flow control.
The communications must also be enabled. From the main screen touch the “next” button to go to the
“inventory” page. Touch “Log in” and type in “5413”. Then touch the “ACS logo” and this will take you
to setup. Touch the “Network Setup” button and ensure that communications is enabled. If it wasn’t then
you’ll need to change it and then reboot the PLC for it to take effect. The Ethernet module takes about 45
seconds to regain communications upon boot.
