Finding the Bus Terminal Controller with the TwinCAT System Manager

An operable ADS connection is necessary in order to set the IP address through the System Manager. With the BC9191 and BC9191-0100, this can only be done via Ethernet.

A functioning Ethernet connection is necessary for the ADS connection via Ethernet. You can test the IP connection with the PING command. By default the Bus Terminal Controller is set to 172.16.21.xxx with the subnet mask 255.255.0.0. Set your PC to the same network class, for instance 172.16.200.100 (sub-net mask 255.255.0.0).

Now use PING to test whether a connection exists:

Now start the TwinCAT System Manager and look for the Bus Terminal Controller using the button highlighted in the image or press F8:

Now look for the Bus Terminal Controller via Ethernet:

Now find your Bus Terminal Controller via Broadcast Search. If you have several Bus Terminal Controllers in your network, you can distinguish them by means of the name.
The name is composed of "BX_" or "BC_" and the last three bytes of the MAC ID. The MAC ID can be found on the underside of the housing of the BC9191.
Example: MAC-ID: 00-01-05-00-1D-C3, then the default name is BC_001DC3.

If the Broadcast Search fails to find a device, check the Ethernet connection.

If the Bus Terminal Controller was addressed via DHCP, you can include the Bus Terminal Controller in your connection via the button Add Route in the Host Name dialog.

If the Bus Terminal Controller was addressed manually or via BootP, select the assigned IP address and establish the connection via the button Add Route.

Acknowledge the password query dialog without making an entry. No password is required for Bus Terminal Controllers. Bus Terminal controllers do not offer password support.

Now select the Bus Terminal Controller you want to connect to and scan the devices connected to it. The Bus Terminal Controller must be in Config mode (Shift-F4).
