Language Ladder diagram
Number of basic steps 102 steps
The number of steps of the FB in a program depends on the CPU module used and input and output definition.
Processing • This FB starts counting when i_bEN (Execution command) turns ON.
• If the setting value of i_uRaNo (Target relay device number) is out of the setting range, o_bErr (Error completion) turns ON
and the processing of this FB is aborted. o_uErrId (Error code) stores the error code "100 (hexadecimal)". For the error code,
refer to Page 5 Error code.

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 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 this FB is used twice or more, precaution must be taken to avoid duplication of the relay device number.
• This FB uses the index register Z9. When using an interrupt program, do not use this index register in the interrupt program.
• Every input must be provided with a value for proper FB operation.
• When clearing current value of o_udOutputOnTotal (Integration value of No. of relay ON times), write K0 to "Instance name
.o_udOutputOnTotal (Integration value of No. of relay ON times)" by DMOV instruction.
• Because the target relay device is counted in ladder, the FB cannot count correctly if the target relay device is turned ON and
OFF twice or more in 1 scan.
• This FB uses latch labels. If the latch label area capacity is insufficient for the contents of the program, a message is
displayed in GX Works3 when the program is compiled. In such a case, correct the program in accordance with the contents
of the message.
• 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 (Application).

Number of basic steps 118 steps
The number of steps of the FB in a program depends on the CPU module used and input and output definition.
Processing • This FB outputs the integration value of the number of output ON times of the relay specified by i_uRaNo (Target relay
device number) in the module specified by i_stModule (Module label) to o_udOutputOnTotal (Integration value of number of
relay ON times) when i_bEN (Execution command) turns ON.
• If o_udOutputOnTotal (Integration value of number of relay ON times) exceeds the value set by i_udCompareCount (Number
of comparisons), o_bFbResult (Comparison operation result) turns ON.
• If the setting value of i_uRaNo (Target relay device number) is out of the setting range, o_bErr (Error completion) turns ON
and the processing of this FB is aborted. o_uErrId (Error code) stores the error code "100 (hexadecimal)". For the error code,
