Example
Connection
Interrupt input X000 to X007
The interrupt input depends on the pulse output destination specified by the DVIT
instruction
*2
as shown in the following table. If the version number of the PLC is
1.30 or higher, the interrupt input can be specified.
FX
3UC PLC Ver. 1.30 or later
If the interrupt input specification function is used, the D8336
register (interrupt input specification register) can specify the
interrupt input number (X000 - X007) for each pulse output
destination.
→ For details on the interrupt input specification method, refer to
Subsection 4.3.7.
FX
3U/FX3UC PLC
*4
Ver. 2.20 or later
If the interrupt input
specification
function is used, the D8336
register (interrupt input
specification
register) can specify the
interrupt input number (X000 - X007) for each pulse output
destination, or the user interrupt input command can be
specified.
→ For details on the user interrupt input command, refer to
Subsection 4.3.7.
The user interrupt input command depends on the pulse output destination as
shown in the following table.
Forward
rotation limit
(LSF)
All input
points
Connect a line to any input.
If the line-connected input is turned on, the forward limit relay must be turned on.
The forward limit relay depends on the pulse output destination as shown in the
following table.
Reverse rota-
tion limit (LSR)
All input
points
Connect a line to any input.
If the line-connected input is turned on, the reverse limit relay must be turned on.
The reverse limit relay depends on the pulse output destination as shown in the
following table:
