Connections for
SafeEthernet/
Networking
Examples
For the networking via SafeEthernet protocol, the devices are equipped - depending
on the design - with two connections arranged on the lower side panel of the case.
See example of a Safety-Related Communication, p. 40.
The various systems can be networked together as required via Ethernet (star or line
configuration). A programming unit (PC) can also be connected wherever required.
Modbus TCP/IP The Modbus serial slave field bus protocol can communicate with the Modbus
TCP/IP protocol via the Ethernet interfaces on the Safety PLC.
Standard Modbus communication transfers the slave address and a CRC checksum
in addition to the instruction code and the data. In Modbus TCP/IP the subordinate
TCP/IP protocol handles this function.

TCP ports and usage
Note: Ensure that no network loops are formed when connecting systems
together. The system must receive data packets along one path only.
Note: More information about Modbus TCP/IP protocol can you find in the online
help of XPSMFWIN.
