CH1 Rate alarm warning detection cycle setting
Medium speed Low speed
Set the cycle to check the change rate of digital output values.
The value of the cycle to detect a rate alarm warning is the product of the value in 'CH1 Rate alarm warning detection cycle
setting' (Un\G522) and the conversion cycle.
For details on the warning output function (rate alarm), refer to the following.

■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Rate alarm warning detection cycle setting
■Setting range
The setting range is from 1 to 32000 (times).
In the channel where a value out of the range is set, a rate alarm warning detection cycle setting range error (error code:
1B9H) occurs.
■Enabling the setting
Turn on and off 'Operating condition setting request' (Y9).
■Default value
The default value is 0 for all channels.
CH1 Rate alarm upper limit value
Medium speed Low speed
