Socket Interface Using CIP Generic Messaging
•
Timeout : Specify the timeout in milliseconds.
•
Structure of ToAddr :
•
Family : Specify the address family. Must be 2.
•
Port : Specify a local port number, or set to 0 (the local port
number will be chosen by the Ethernet subsystem). For TCP
client operations, specify 0 unless you want a specific local port
number. For TCP server communications, specify the port
number on which to accept incoming connection requests. For
UDP, to receive datagrams on a specific port, you must specify a
local port number.
•
Addr : Specify an IP address. Typically, set to 0 (any address).
•
BufLen : Specify the number of bytes of data to write.
•
Reserved : Specify 0.
•
Buf : Specify the data to write.
•
BufLen : the number of bytes that were written.
•
Reserved : Contains 0.
Inline Indirection functionality
You can use Inline Indirection functionality for N file in Write service.
Extended Routing Info File(RIX)
Specify RIX file
To Address in MultiHop tab
127.0.0.1
Considerations :
For TCP connections, ToAddr is ignored. Connectionless UDP messages may use the address
stored in the open connection service.
