Interrupt Functions
Section 6-1
Procedure
PLC Setup
Click the Built-in Input Tab to display the
Interrupt Input
settings (at the bottom
of the tab). Set the input function to
Interrupt
for each input that will be used
as an input interrupt.
Note
(1) Interrupt Input settings IN0 to IN7 correspond to input interrupt numbers
0 to 7.
(2) When using an input as a general-purpose (normal) input, set the input
function to
Normal
.
Writing the Ladder
Program
MSKS(690) Settings
The MSKS(690) instruction must be executed in order to use input interrupts.
The settings made with MSKS(690) are enabled with just one execution, so in
general execute MSKS(690) in just one cycle using an up-differentiated condi-
tion.
Select the input interrupts.
• Determine the inputs to be used for input
interrupts and corresponding task numbers.
↓
Wire the inputs.
• Wire the inputs.
↓
Set the PLC Setup.
• Use the CX-Programmer to select the inter-
rupt inputs in the PLC Setup.
↓
Write the ladder program.
• Write the programs for the corresponding
interrupt task numbers.
• Use MSKS(690) to specify up-differentiation
or down-differentiation.
• Use MSKS(690) to enable input interrupts (in
direct mode).
