Input Interruption (I00
to I50
)
The PLC (main unit) is provided with an input interruption function and has six interruption input points.
Make sure that the ON duration or OFF duration of interruption input signals is 10 s or more (X000, X001,
X003 and X004) or 50 s or more (X002 and X005).
→
For details on programming, refer to the programming manual.
10.4.1 Allocation of pointers to input numbers (input signal ON/OFF duration)
10.4.2 Cautions for input interruption
1. Non-overlap of input numbers
The input terminals X000 to X005 can be used for high-speed counter, input interruption, pulse catch, SPD,
ZRN and DSZR instructions and general-purpose inputs.
Take care not to overlap the input numbers.
2. Cautions in wiring
It is recommended to use shielded twisted-pair cables for connection cables.
