Operation error
Error code Description
(SD0)
3400H An invalid operation (such as division by zero) is performed.
3402H Input data, operation constant, tag data, or operation result within a function block is a subnormal number or NaN (not a number).
3403H An overflow has occurred.
3405H The sampling interval time for AT1 (AT1ST) setting is less than 0.
The time-out interval for AT1 (AT1TOUT1) setting is less than 0.
The time-out interval after maximum slope for AT1 (AT1TOUT2) setting is less than 0.
The execution cycle (T) setting is less than 0.
The value divided the sampling interval time for AT1 (AT1ST) by the execution cycle (T) exceeds 32767.
The value divided the time-out interval for AT1 (AT1TOUT1) by the execution cycle (T) exceeds 32767.
The value divided the time-out interval after maximum slope for AT1 (AT1TOUT2) by the execution cycle (T) exceeds 32767.
The control cycle (CT) setting is less than 0.
The execution cycle (T) setting is less than 0.
The value divided the control cycle (CT) by the execution cycle (T) exceeds 32767.
