PROGRAMMING MANUAL
Comment
To program, monitor and debug
the project with Trajexia Tools.
To communicate with any FINS
master, for example PLC, HMI, or
personal computer.
To communicate to any FINS
server, for example PLC or
another Trajexia unit.
To communicate with any Host
Link slave, for example an
OMRON PLC.
To communicate with any Host
Link master, HMI typically.
This protocol is created and han-
dled using BASIC commands.
To exchange word variables with
any PROFIBUS master.
To exchange word variables with
any DeviceNet master.
To communicate with supported
MECHATROLINK slaves. This
protocol is transparent to the
user.
4.2 Ethernet
The TJ1-MC__ has a standard 10/100 Mbps Ethernet port. You can use a
crossover or a patch Ethernet cable to connect the TJ1-MC__ to a PC.
To configure the interface, set these parameters:
/i
Item Default value
IP address 192.168.0.250
Subnet mask 255.255.255.0
Gateway 0.0.0.0
Make sure that the IP address of the PC is in the same range as the TJ1-
MC__: if the IP address of the TJ1-MC__ is aaa.bbb.ccc.ddd, the IP address
of the PC must be aaa.bbb.ccc.xxx, where xxx is 000 to 255 other than ddd.
You can change the IP address of the TJ1-MC__ to match the IP address of
your PC if you connect to the PC through a network hub or switch. For
example, of the IP address of the PC is 192.200.185.001, you can set the IP
address of the TJ1-MC__ to 192.200.185.002.
Note
The TJ1-MC__ does not have DHCP functionality, therefore it can-
not assign an IP address to a PC.
The subnet mask of the TJ1-MC__ is generic. It does not need to match with
the subnet mask of the PC.
Use the Ethernet command to read or write the Ethernet settings. It is
necessary to power off and on again the units for the changes to take effect.
You can check the IP address of the TJ1-MC__ with the Trajexia Tools
command-line and the Ethernet command: Type the command Ethernet(0,
-1, 0) at the command-line, and the IP address of the TJ1-MC__ shows on
the command-line.
Note
You need to set the power of the Trajexia system off and back on
before the change of the IP address takes effect.
Comment
Set one IP address that is unique in the network.
Set the same subnet that the LAN uses.
The gateway is necessary to have remote access
from another LAN.
