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 30 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 (When the Q
compatible mode function is used)
■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' (Y9) 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.
CH1 Decrease 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 30 Rate Control Function
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Decrease digital limit value
CH Decrease digital limit value (When the Q
compatible mode function is used)
■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 decrease 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' (Y9) to enable the setting.
■Default value
The default value is 64000 for all channels.
■Precautions
When a value exceeding 32767 is set in 'CH1 Decrease digital limit value' (Un\G516) with the program, the value must be
input in hexadecimal.
