Modbus Plus
Communication
If a PCI or PCMCIA Modbus Plus communication card has been installed in your PC,
and if you have a Modbus Plus network cable (at least a straight cable with one DB9
male connector at each side), you will also be able to communicate with the
controller thorough its Modbus Plus port, provided the Modbus Plus drivers have
been previously and properly installed. This port also reacts on a non configured
controller unit.
Reference AS MBKT 185 gives you two of these terminal DB9 connectors
The controller's Modbus Plus port address may be manually changed with the
keypad.
Ethernet
Modbus/TCP
Communication
If a 140 NOE 771 xx Ethernet module is installed in the rack, an Ethernet connection
is possible allowing communication from your PC to the Ethernet communication
module (NOE 771 xx). If you use a nonconfigured CPU unit, the non configured NOE
Ethernet port will respond to an IP Address that is derived from its MAC address.
Example: suppose the MAC Address of the targeted NOE adapter is
00.00.54.10.BF.A6. The default IP Address would be 84.16.191.166
Provided your PC has an IP address (and a subnet mask) compatible with this
default IP address, a ping command would easily check if the NOE adapter
responds to that address. Through this default IP address, you can download an
application program into the controller.
The project configuration will usually assign a particular address to this port, and
after starting, the controller responds to this new IP address.
USB
Communication
Provided you own the required communication cable (referenced UNY XCA USB
033), you will be able to use the USB port now available with the new Modicon
Quantum High End CPUs.
