136 steps
The number of FB steps integrated in the program varies depending on the CPU module used, the input/output definition, and
the setting options of GX Works3. For the setting options of GX Works3, refer to GX Works3 Operating Manual.
• When i_bEN (execution command) is turned on, this function closes a connection for data communication with target device.
• The function closes all connections if FFFF is specified for the connection number in the input argument.
• If the function fails to close even one connection among those specified to be closed, it is completed with an error.
Macro type

[For normal completion]
i_bEN

o_bOK
o_bErr

[For error completion]
i_bEN
o_bENO

o_bErr
o_uErrId
• This FB does not include the error recovery processing. Program the error recovery processing separately in accordance
with the required system operation.
• This FB uses the SP.SOCCLOSE instruction.
• Turn off i_bEN (Execution command) after o_bOK (Normal completion) or o_bErr (Error completion) is turned on. By turning
off i_bEN (Execution command), o_bOK (Normal completion) or o_bErr (Error completion) is turned off and o_uErrId (Error
code) is cleared to 0. However, because the SP.SOCCLOSE instruction which is a pulse instruction in the FB is used, if a
write is performed while the FB is executed, the instruction may not be executed, and o_bOK (Normal completion) and
o_bErr (Error completion) may not turn on. If this happens, turn i_bEN (Execute command) from off to on again.
• This FB cannot be used in an interrupt program.
• Do not use this FB in programs that are executed only once, such as a subroutine program or FOR-NEXT loop, because
i_bEN (Execution command) cannot be turned off and the normal operation cannot be acquired. Always use this FB in
programs that can turn off i_bEN (Execution command).
• Every input must be provided with a value for proper FB operation.
• Set the module parameters in GX Works3 in accordance with the connected equipment and system. For the module
parameters, refer to the MELSEC iQ-F FX5 User's Manual (Ethernet Communication).
