Appendix 3 Buffer Memory Areas
CH1 Process alarm lower lower limit value
Set a lower lower limit value of the alert output function (Process alarm).
For details on the alert output function, refer to the following.
Page 30 Alert Output Function
■Buffer memory address
The following shows the buffer memory address of this area.
•CH Process alarm lower lower limit value
•CH Process alarm lower lower limit value (in Q compatible mode)
■Setting range
The setting range is from -32768 to 32767.
■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 process alarm, configure the 4-step settings for the process alarm upper upper limit value,
upper lower limit value, lower upper limit value, and lower lower value.
• In the channel where a set value does not satisfy the condition "the upper upper limit value the upper
lower limit value the lower upper limit value the lower lower limit value", a process alarm upper lower
limit value setting range error (error code: 1BH) occurs.
• Since the default value is 0, change the setting value.
• When the scaling function, shift function, digital clipping function, or difference conversion function is used,
alert targets are digital operation values to which the operation of each function is reflected. Be sure to
consider operation results of each function to set values.
