CH1 Set value check code
Normal
When a set digital value is out of the setting range, a check code is stored.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Set value check code
■Check target
The check target varies depending on the operation mode.
Operation mode
Normal output mode
Wave output mode
Inter-module synchronization mode
*1 The buffer memory addresses in which digital values outside the setting range have been registered can be checked in the following:
'CH1 Wave output digital value outside the range address monitor' (Un\G440, Un\G441) (Page 165 CH1 Wave output digital value
outside the range address monitor)
■Stored check codes
Check code
000FH
00F0H
00FFH
Once the check code is stored, the code is not reset even when the digital value falls within the setting range.
When the scaling function is used, the value of 'CH1 Digital value' (Un\G460) which has undergone a scale conversion is
checked. Note that some errors may be observed in the target digital value for a check code to be stored due to the
calculation error of scale conversion when a scale-converted value exceeds the setting range.
■Resetting the check codes
Set a digital value within the setting range and turn on and off 'Error clear request' (YF).
CH1 Wave output status monitor
