Wiring of the Sercos Bus
NOTE: The Sercos bus can be operated in a single-line architecture.
The following wiring of the Sercos bus relates to the example project described in this guide. The Sercos slaves can alternatively be connected in any other order.

Step
|
Action
|
|
1
|
Connect the Sercos cable to the Ethernet 1 port of the Logic/Motion Controller. The port is labeled with SERCOS CN1 on the device.
|
|
2
|
At the SLC, connect this cable to any of the Sercos III RJ45 ports.
|
|
3
|
Continue the Sercos bus by plugging a second cable to the free Sercos III RJ45 port of the SLC, and connect it to any of the Sercos ports of the TM5NS31 bus coupler.
|
|
4
|
If required, continue the Sercos bus to the next TM5NS31 bus coupler or any other Sercos slave (drives, etc.) used.
|
The TM5NS31 bus coupler detects the connected TM5/TM7 I/O devices automatically and creates a corresponding local process image of the given hardware configuration. Therefore, no further signal wiring is required.
