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 reads the data received to the connection specified by the
input argument.
• If an error occurs during data receiving, o_bErr (error completion) is turned on, and the error code is stored in o_uErrId (error
code). Refer to Page 11 Error code for details on the error codes.

• 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.SOCRCV 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.SOCRCV 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).
Range Description
ON, OFF Specify the timing of executing data read processing.
• OFF: Start reading soon after the module FB starts.
• ON: Start reading in the first END processing after
the module FB starts.
The setting is ignored in FX5U/FX5UC CPU because it
reads the data in the END processing.
