4.3.7 Designation of Interrupt Input Signal for DVIT Instruction
The interrupt input signal of the interrupt positioning (DVIT) instruction depends on the pulse output
destination device as shown in the following table.
Use an FX
3UC PLC Ver. 1.30 or later to use the interrupt input specification function.
Use an FX
3U/FX3UC PLC Ver. 2.20 or later to set the user interrupt input command.
→ For operation of DVIT instruction, refer to Chapter 9.
*1. Devices related to Y003 (pulse output destination) are only valid if two FX
3U-2HSY-ADP adapters are
connected to the FX
3U PLC.
Designation of interrupt input using M8336 interrupt input
specification function:
1) Turn on M8336.
2) Set the interrupt input number (X000 to X007) in D8336, or
specify the user interrupt input command
*1
.
→ For specifying the settings, refer to the following description.
