TRUE when the digital output value drops below the switch-on value for low
limit alarm.
TRUE when the limit alarm function is active.
TRUE when the maximum and minimum value hold function is active.
TRUE when an error has occurred.
Control flags are allocated to the CPU's output area.
The I/O addresses in the table show offset addresses. I/O addresses actu-
ally allocated are based on the first word number allocated to the unit.
Example: If the first word number is 10, the address numbers for the dis-
connection detection execution flag and the error flag reset flag on channel
0 will be Y100 and Y10F, respectively.
