Number of basic steps 132 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.
Processing • When i_bEN (Execution command) is turned ON, the received data is read from the specified received data storage channel
and saved into the received data storage device.
• If an error occurs while receiving the data, o_bErr (Error completion) turns ON, and the error code is stored in o_uErrld (Error
code). Refer to Page 39 Error code for details on the error codes.
FB compilation method Macro type
FB operation Pulsed execution (multiple scan execution type)
Timing chart of I/O signals [For normal completion]
[For error completion]
(For instruction error)
Restrictions or precautions • 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 GP.RECV 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 GP.RECV 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).
• When using several of these FBs, make sure that the receive data storage channel do not overlap.
• 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 (CC-Link IE).
