250 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.
• Starts pulse measurement by turning i_bEN (Execution command) on.
• If the set value of the target channel is outside the setting range, o_bErr (Error completion) turns on and the processing of
this FB is aborted. In addition, the error code 100 (hexadecimal) is stored in o_uErrId (Error code). For the error code, refer
to Page 36 Error code.
• If an error occurs when starting pulse measurement, o_bErr (Error completion) turns on and the processing of this FB is
aborted. In addition, the error code is stored in o_uErrId (Error code). For the error codes, refer to MELSEC iQ-F FX5
User's Manual (Application).
