FB operation
Processing
• As i_bEN (execution command) turns on, a start or stop request for the wave output of a specified channel or all channels
is written to the buffer memory.
• As i_bEN (execution command) turns on, the FB outputs the values of 'CHWaveform output status monitor' (Un\G401,
Un\G601, Un\G801, Un\G1001) . When an individual channel is specified in the input label, only this specified channel
updates a wave output status monitor value and the other channels output 0. When all channels are specified in the input
label, all the channels output wave output status monitor values. The number of channels with all channels specified
depends on the module type.
• As i_bEN (execution command) turns on, the FB always starts its execution.
• To start wave output once again, after the wave output ends, change i_uStartStopReq (waveform output start/stop request)
from 1 (waveform output start request) to 0 (waveform output stop request), and then set 1 (waveform output start request)
again.
• The wave output setting is enabled only when the output mode setting is set to the wave output mode.
• When the setting values of target channel are out of range, o_bErr (Error completion) turns on, and the FB processing are
stopped. Also, Error code 100 (Hexadecimal) is stored in o_uErrId (Error code). For the error code, refer to Page 37
Error code.
• When the setting values of module type are out of range, o_bErr (Error completion) turns on, and the FB processing are
stopped. Also, Error code 102 (Hexadecimal) is stored in o_uErrId (Error code). For the error code, refer to Page 37

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.
• Label: 0.02 K point (Word)
• Latch label: 0 K point (Word)
The amount of labels used in the program varies depending on the CPU module used, the device specified in an argument
and the option setting of GX Works3. For the option setting of GX Works3, refer to GX Works3 Operating Manual.
