(21)CH1 Process alarm lower lower limit value (Un\G86) to CH8 Process alarm
A
upper upper limit value (Un\G117) Common
Set the digital output value range for each channel. Configure the 4-step setting of process alarm upper upper
limit value, process alarm upper lower limit value, process alarm lower upper limit value, and process alarm lower
lower limit value.
For details on warning output function (process alarm), refer to the following.
• Warning Output Function (Process Alarm) (
Page 85, Section 8.9)
(a) Setting range
• Setting range is -32768 to 32767.
• When a value which does not satisfy the formula of process alarm upper upper limit value  process alarm
upper lower limit value  process alarm lower upper limit value  process alarm lower lower limit value is
set to a channel, an error occurs in the channel. The error code is stored in Latest error code (Un\G19),
and Error flag (XF) turns on. The operation is performed in the setting configured before the error
occurrence.
• When the following functions are used, warning targets are scaling values that reflect the operations of
each function. Set values considering operation results of each function.
