Manual SD6
If you would like to repeat the data exchange from steps 4 to 6, mark the
module in the project window and press the
Assignment
button near the
bottom. This is possible when a connection is set up.

Setting up a connection manually
14.3.3.1
IP address and subnet mask
An IP address is divided into a network section and a device section by the
subnet mask. The subnet mask can be represented in binary format, for
example, as a series of numbers with the left side consisting only of the number
1 and the right side consisting only of the number 0.
1111 1111.1111 1000.0000 0000.0000 0000 = 255.248.0.0
The section of the subnet mask with the number 1 shows which part of the IP
address indicates the address of the subnet (the network section). The other
part with the number 0 shows the part of the IP address that represents the
address of the device in the subnet (device section).
4. Click the
OK
button.
The
Assignment
dialog appears:
The dialog shows all the drive controllers that are connected with the
computer via the gateway device.
5. In this dialog you define how the computer will exchange data with the IGB
network. In the example shown here, the main drive from the project is
sent to the drive controller with serial number 7000043. The drive
controller with serial number 7000048 is a new drive controller created in
the project.
6. Click the
Start
button.
Data is exchanged.
The direct connection is set up and data is exchanged.
Information
To coordinate the IP addresses of the gateway device and the
computer, you have the option of changing the IP address of either
the computer or the gateway device. However, since you generally
need administrator rights to change the IP address of the computer,
we recommend changing the IP address of the gateway device.
Information
Please note that the device has two RJ45 sockets (X3A and X3B).
Since one socket must be access concretely for a direct connection,
the related parameters are created as array parameters. Element 0
contains the settings for socket X3A and element 1 for socket X3B.
Make the settings described in this section appropriately for the
socket with which you will connect the gateway device with the
computer.
