10.4 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.
Example:
When the input interrupt pointer "I001" is used, X000 is occupied. Therefore, it is impossible to use C235,
C241, C244, C246, C247, C249, C252 and C254, input interruption pointer I000, pulse catch contact M8170
and SPD, ZRN and DSZR instructions at the same time.
