CH1 Rate alarm lower limit value
Set a lower limit value of the change rate of digital output values to detect a rate alarm.
For details on the alert output function, refer to the following.

■Buffer memory address
The following shows the buffer memory address of this area.
• CH Rate alarm lower limit value

■Setting range
The setting range is from -32768 to 32767 (-3276.8 to 3276.7%). (Set it in a unit of 0.1%.)
■Enabling the setting
Turn on and off 'Operating condition setting request' (Y9).
■Default value
The default value is 0 for all channels.
• When using the rate alarm, configure the 2-step settings for the rate alarm upper limit value and lower limit
value.
• In the channel where a set value does not satisfy the condition "the rate alarm lower limit value  the rate
alarm upper limit value", a rate alarm upper/lower limit setting value inversion error (error code: 1BAH)
occurs.
• Since the default value is 0, change the setting value.
CH1 Input signal error detection setting
Set a condition for detecting an input signal error.
For details on the input signal error detection function, refer to the following.

If a value other than the above is set, an input signal error detection setting range error (error code: 1C0H) occurs.
If Simple disconnection detection (4) is selected for the channel where the input range setting is other than the extended
mode, a disconnection detection enabled range setting range error (error code: 1C6H) occurs.
