• Wave output start request is accepted only when the CPU module is in the RUN status. When a value in
'CH1 Wave output start/stop request' (Un\G462) is changed to Wave output start request (1) with the CPU
module status other than in the RUN state, the wave output is not started.
• Wave output stop request is accepted when the CPU module is in the RUN or STOP status.
• Wave output pause request is accepted only when the CPU module is in the RUN status.
• When a value other than 0 to 2 is set to 'CH1 Wave output start/stop request' (Un\G462), an error occurs.
The error code (1D0H) is stored in 'Latest error code' (Un\G0), 'Error flag' (XF) turns on, and the ERR LED
turns on. However, the process will continue.
• When a value out of the digital value range is set for the output range, a digital value setting range error
(error code: 191H) occurs.
Checking the setting for the wave output function
The setting for the wave output function can be checked in the following buffer memory areas.
Item
Wave output status monitor
Wave output conversion cycle
monitor
Wave pattern output count monitor
Wave output current address
monitor
Wave output current digital value
monitor
Wave output digital value outside
the range address monitor
Wave output warning address

For details on each buffer memory area, refer to the following.
Page 136 Details of buffer memory addresses
Description
The wave output status is stored in this area.
The conversion cycle of the wave output is stored in 32-bit signed binary in this area. The unit of the stored value is s.
The output count of the wave pattern is stored in this area.
The buffer memory address of the currently output wave data is stored in 32-bit signed binary in this area.
The digital input value which is being currently output is stored in this area.
When the wave data with the digital input value out of the setting range is output, the buffer memory address to register
the wave data is stored in 32-bit signed binary in this area. When the multiple wave data with the digital input value out of
the setting range are detected, only the buffer memory address of the wave data detected first is stored.
The buffer memory address of the wave data where a warning has occurred is stored in 32-bit signed binary in this area.
When a warning has occurred in the multiple wave data, only the buffer memory address of the wave data where the
warning occurred first is stored.
