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