CH1 Alarm output lower limit value
Set the range of a digital value used for alarm output.
For the alarm output function, refer to the following.
Page 193 Alert output function
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Alarm output lower limit value
CH Alarm output lower limit value (in FX3
allocation mode function)
■Setting range
The possible setting range is from -32768 to +32767. A channel for which any value not meeting the condition of "alarm output
upper limit value > alarm output lower limit value" causes an alarm output upper/lower limit value reverse error (error code:
1B1H).
If 'CH1 alarm output setting' (Un\G508) is set to Disable (1), the setting for 'CH1 alarm output lower limit value' (Un\G512) will
be ignored.
■Enabling the setting
Turn on and off 'Operating condition setting request' (Un\G70, b9) 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 Increase digital limit value
Set the increment value per conversion cycle (80 s) when using the rate control function.
For the rate control function, refer to the following.
Page 195 Rate control function
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Increase digital limit value
CH Increase digital limit value (in FX3
allocation mode function)
■Setting range
The setting range is from 0 to 64000 (FA00H). If a value out of the setting range is set for a channel where the conversion and
rate control are enabled, a digital limit value range error (error code: 1B9H) occurs.
When the scaling setting is enabled, the increase digital limit value of the input digital value converted within the scaling range
is applied.
■Enabling the setting
Turn on and off 'Operating condition setting request' (Un\G70, b9) to enable the setting.
■Default value
The default value is 64000 for all channels.
■Precautions
When a value exceeding 32767 is set in 'CH1 Increase digital limit value' (Un\G514) with the program, the value must be input
in hexadecimal.
