the setting options of GX Works3. For the setting options of GX Works3, refer to GX Works3 Operating Manual.
Processing • As i_bEN (execution command) turns on, the wave output settings of a specified channel or all channels are written.
• The wave output setting is enabled only when the output mode setting is set to the wave output mode. The wave data for
analog output is required to be set in advance.
• The set value is enabled by turning on and off 'Operating condition setting request' (Un\G70.b9) or executing the operating
• condition setting request operation FB (M+FX5-4DA _RequestSetting).
• 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 18
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 18
Error code.
