NULL_ARRAYOFBYTE_1
NULL_ARRAYOFBYTE_2
Data type
sControl Sets whether or not send processing or receive
(STRUCT) processing is required.
BOOL Send processing:
Required (TRUE)/Not required (FALSE)
* If send processing is required, but receive processing
is not required:
The program will skip receive processing and go to
close processing without waiting for receive data in
send processing. Specify this value when response
data is not sent back to the command sent.
BOOL Receive processing:
Required (TRUE)/Not required (FALSE)
* If both send processing and receive processing are
required:
The program will wait for the arrival of receive data
after send processing. The program will go to receive
processing after checking the arrival of receive data.
Specify this value when response data is sent back to
the command sent.
BOOL Send/Receive Processing Required Setting Error Flag
(This flag is set if there is a setting error.)
Data type
_sSOCKET Internal socket service instruction initialization data
(Retain constants: Enabled)
Initial value (Handle:=0, SrcAdr:=(PortNo:=0, IpAdr:=''),
DstAdr:=(PortNo:=0, IpAdr:=''))
(Used for all socket instructions.)
ARRAY[0..0] Internal send socket service instruction initialization data
OF BYTE (Retain constants: Enabled)
Initial value [0] (Use for the SktTCPSend instruction)
ARRAY[0..0] Internal receive socket service instruction initialization
OF BYTE data (Retain constants: Disabled)
Initial value [0] (Use for the SktTCPRcv instruction)
