• Wave output start request is accepted only when the CPU module status is RUN. If 'CH1 Wave output start/
stop request' (Un\G462) is changed to Wave output start request (1) in CPU module status other than RUN,
the wave output will not start.
• Wave output pause request is accepted only when the CPU module status is RUN or STOP.
• Wave output pause request is accepted only when the CPU module status is RUN.
• If 'CH1 Wave output start/stop request' (Un\G462) is set to a value other than 0 to 2, an error will occur. A
logging cycle setting disable error (error code: 1D0H) is stored in 'Latest error code' (Un\G0), 'Error flag'
(Un\G69, b15) and the ERROR LED turn on. In this case, the wave output will continue.
• An attempt to output a value out of the digital value range set with the output range causes an error,
resulting in occurrence of a digital value setting range error (error code: 191H).
■Checking the wave output function status
The wave output function status can be checked with the following buffer memory addresses.

Description
An area to store the wave output status.
Area in which the conversion cycle of wave output is stored. The unit of the stored value is s.
An area to store the number of times the wave pattern was output.
An area to store the buffer memory address of the currently output wave data.
An area to store the currently output digital input value.
When wave data that contains a registered digital input value out of the setting range is output, this area is used to store
the registration destination buffer memory address of that wave data. When a digital value outside the setting range is
detected with multiple pieces of wave data, this area stores the buffer memory address of only the first detected piece of
data.
An area to store the buffer memory address of the wave data when an alarm occurred. When an alarm occurs due to
multiple pieces of wave data, only the buffer memory address of the wave data causing the first alarm is stored.
