0, and o_bFbResult (Comparison operation result) turns ON→OFF.
FB details
No. Variable name Name Data type Default value Description
(5) o_bENO Execution status Bit OFF ON: The execution command is ON.
OFF: The execution command is OFF.
(6) o_udOutputOnTotal Integration value of
number of relay ON
times
Double Word
[Unsigned]
0 Stores the counted integration value of the number of
times the specified relay device number has turned
ON.
*1
(7) o_bOK Normal completion Bit OFF When this label is ON, it indicates that the FB is
counting the relay ON times.
(8) o_bErr Error completion Bit OFF When this label is ON, it indicates that an error has
occurred in the FB.
(9) o_uErrId Error code Word [Unsigned] 0 Stores the error code that occurred in the FB.
(10) o_bFbResult Comparison operation
result
Bit OFF
*1
When this label is ON, it indicates that
o_udOutputOnTotal (Integration value of number of
relay ON times) is larger than i_udCompareCount
(Number of comparisons).

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,
refer to Page 8 Error code.
