• Wave output start request is accepted only when the CPU module is in the RUN state. When a value in
'CH1 Wave output start/stop request' (Un\G462) is changed to Wave output start request (1) with a CPU
module state other than 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 state.
• Wave output pause request is accepted only when the CPU module is in the RUN state.
• When a value out of the digital setting range, not the one set in the output range, is tried to be output, a
digital value setting range error (error code: 191H) occurs.
Checking the progress for the wave output function
The progress 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 monitor
For details on each buffer memory area, refer to the following.
Page 153 Details of buffer memory areas
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 value which is being currently output is stored in this area.
When the wave data with the digital value out of the setting range is output, the buffer memory address where that
wave data is registered is stored in 32-bit signed binary in this area. When the multiple wave data with the digital
values 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.
