5.5 Upper Limit / Lower Limit Comparison Function
■
Overview of the function
● This function compares acquired analog input data with the preset upper limit and lower limit.
When the acquired data exceeds the upper limit (digital conversion value is larger
than the upper limit comparison ON level)
Turns ON the "Ch* upper limit comparison status".
When the acquired data exceeds the lower limit (digital conversion value is smaller
than the lower limit comparison ON level)
Turns ON the "Ch* lower limit comparison status".
● When Analog_8IN parameters > Upper and lower limit comparison is set to "Execute",
turn ON "Ch* upper limit/lower limit comparison request" to execute the function.
● The upper limit / lower limit comparison processing is executed on a channel-by-channel
basis.

(2) When a value that is equal to or larger than the upper limit comparison ON level is detected, "Ch*
upper limit comparison status" will turn ON.
(3) When a value that is equal to or smaller than the upper limit comparison OFF level is detected, "Ch*
upper limit comparison status" will turn OFF.
(4) When a value that is equal to or smaller than the lower limit comparison ON level is detected, "Ch*
lower limit comparison status" will turn ON.
(5) The following I/O will be forcibly turned OFF if "Ch* upper limit / lower limit comparison request" is
turned OFF.
