If Service PC is connected to
distant SWT 3000 (address 2,
3 or 4)
If RM data transmission is
active in distant SWT 3000 via
SSB (address 3 or 4)
The SSB interface of the SWT 3000 system has the same characteristics as the RM-2 interface of the PowerLink
systems.
The following figure shows the remote connection to the SWT 3000 in station A via TCP/IP connection. The
access to the SWT 3000 devices in station B and C is possible when the inband RM-Channel is activated.

Use a crossed cable for the SSB to SSB connection in station B (refer to
Configure one of the SSB interfaces as Slave and the other one as Master.
For the service program PowerSys connection, select Remote Device in the Data Source menu or use the
corresponding button (Data Source Remote Device) in the menu bar as follows:

Activation of an SSB data transmission from another SWT 3000 is possible
without influencing the service PC connection at the Ethernet (ETH) or local
(USB) interface. Because the SSB connection is the second one, only read
permission is available, while the first connection (service PC) has read and
write access.
Connection of the service PC to the Ethernet (ETH) or local (USB) interface
does not block the SSB transmission. Because the connection is the second
one, only read permission is available, while the first connection (SSB) has
read and write access (if configured).
