Outputs consists of 32 bits representing the 32 Outputs. By default Outputs are
disabled to generate interrupts.
External Interrupt Task
Offset Every Output that is enabled to generate interrupts is assigned two External Inter-
rupt Tasks in the CJ-series CPU Unit. For this purpose all 32 Outputs are assigned
in sequential order to consecutive External Interrupt Tasks starting from Output 0.
By defining an Offset you determine the External Interrupt Task numbers of the
(first two) External Interrupt Tasks that are assigned to Output 0. The remaining 31
Outputs are assigned to the respective External Interrupt Task numbers in
increasing order starting from “ 2”.
* The assigned External Interrupt Task number is executed at a rising/falling
edge of the corresponding Output bit in the Unit Output Pattern.
For every Output the assigned External Interrupt Task number can be calculated
with the following formula (‘O’ = Output):
Assigned External Interrupt Task Number to the
•
rising edge of the Output bit is equal to: 2xO
•
falling edge of the Output bit is equal to: 2xO+1
