CH1 Rate alarm alert detection cycle setting
Set the cycle to detect the change amount of digital output values.
The value of the cycle to detect a rate alarm alert is the product of the value in 'CH1 Rate alarm alert detection cycle setting'
(Un\G522) and the conversion cycle.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Rate alarm alert detection cycle setting
CH Rate alarm alert detection cycle setting (In FX2N
allocation mode function)
■Setting range
The possible setting range is from 1 to 32000 (times).
■Enabling the setting
Turn offonoff 'Operating condition setting request' (Un\G70, b9) to enable the setting.
■Default value
The default value is set to 0.
• A channel where the set value is out of the range causes a rate alarm detection cycle setting range error
(error code: 1B9H).
• Since the default value is 0, change the setting value when setting the rate alarm function.
CH1 Rate alarm upper limit value
Set an upper limit value of the change rate of digital operation values to detect a rate alarm.
For details on the alert output function, refer to the following.
Page 354 Alert output function
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Rate alarm upper limit value
CH Rate alarm upper limit value (In FX2N allocation mode
function)
■Setting range
The possible setting range is from -32768 to +32767.
Unit of the setting value differs depending on the setting of 'Rate alarm change rate selection' (Un\G299).

Digital output value specification (1)
■Enabling the setting
Turn offonoff 'Operating condition setting request' (Un\G70, b9) to enable the setting.
■Default value
The default value is set to 0.
