Input Parameters
Parameter name Function Data type
Valid range
(Default)
Validation timing
Execute
The instruction is
executed when
Execute
changes from FALSE to
TRUE.
BOOL
TRUE or FALSE
(FALSE)
SocketNum
Set the number of the
Socket
USINT
1~8
(The variable
value must be
set.)
When Execute
changes from
FALSE to TRUE
OpenMode
Mode to use the controller
TRUE: Client mode
FALSE: Server mode
BOOL
TRUE or FALSE
(FALSE)
When Execute
changes from
FALSE to TRUE
Note:
1. ETH_Socket_Open is used to enable Socket. After ETH_Socket_Open is executed, the controller will try
to make connection with other node or wait for other node to send out the link request.
2. When OpenMode is TRUE, the controller is in Client mode. After ETH_Socket_Open instruction is
executed, the controller sends out the link request to the target node.
When OpenMode is FALSE, the controller is in
Server mode. After ETH_Socket_Open instruction is
executed, the controller waits for the link request from the target node.
3. If Socket UDP is selected as the Socket mode, selecting TRUE or FALSE for OpenMode will have no
impact on the use of the instruction.
