CH1 Alert output upper limit value
Set the range of digital values to output alerts.
For the alert output function, refer to the following.
Page 28 Alert Output Function
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Alert output upper limit value
CH Alert output upper limit value (When the Q
compatible mode function is used)
■Setting range
The setting range is from -32768 to 32767. In the channel where a set value does not satisfy the condition "alert output upper
limit value > alert output lower limit value", an alert output upper/lower limit value inversion error (error code: 1B1H) occurs.
When 'CH1 Alert output setting' (Un\G508) is set to Disable (1), the setting of 'CH1 Alert output upper limit value' (Un\G510) is
ignored.
■Enabling the setting
Turn on and off 'Operating condition setting request' (Y9) to enable the setting.
■Default value
The default value is 0 for all channels.
■Precautions
When the shift function is used, always set a value in consideration of 'CH1 Input value shift amount' (Un\G480).
CH1 Alert output lower limit value
Set the range of digital values to output alerts.
For the alert output function, refer to the following.
