Restrictions and precautions
• The FB does not include the error recovery processing. Prepare the error recovery processing separately to suit the actual
system and the expected operation.
• The FB cannot be used in an interrupt program.
• Using the FB in a program that is to be executed only once, such as a subroutine program or a FOR-NEXT loop, has a
problem that i_bEN (Execution command) can no longer be turned off and normal operation is not possible; Always use the
FB in a program that is capable of turning off i_bEN.
• Change the memory/device setting of the CPU parameter so that the memory capacity required to use the FB is secured. If
the setting is not changed, an error may occur in GX Works3.
• Turning off i_bEN stops the processing that is being performed. Turning off i_bEN during the processing has a problem that
the connection can no longer be closed; Turn off i_bEN after o_bOK (FB completed successfully) or o_bErr (FB completed
with an error) is turned on.
• During the execution of this FB, perform exclusive control to avoid using the same connection number.
• Use the FB in an environment where the scan time is 500ms or less.
• When this FB is changed online, o_bENO, o_bOK, o_bErr, and o_uErrId are not retained. Turn off and on i_bEN after the
online change.
• After the completion of the FB, wait for 500ms or more before subsequent execution of the FB if it specifies a connection
having the same information (external device IP address, own station port number, and external device port number) as the
connection specified by the preceding FB. If the subsequent execution must be started within 500ms, executing the FB
after changing the own station port number on the Active open side is recommended.
• Do not perform the open/close processing instruction (SP.SOCOPEN/SP.SOCCLOSE) in the socket communications
whose connection number is used in the FB. Doing so affects the FB operation.
