5.7 Pulse Catch (M8170 to M8177)
The PLC (main unit) is provided with a pulse catch function and has 8 pulse catch input points.
1. Allocation of special memories to input numbers (ON duration of input signals)
→ For details on programming, refer to the programming manual.
→ For the wiring, refer to Section 7.3.
2. Non-overlap of input numbers
The input terminals X000 to X007 can be used for high-speed counter, input interruption, pulse catch, speed
detection (SPD) instructions and general-purpose input.
Take care not to overlap the input numbers.
Example:
When the pulse catch input contact M8170 is used, X000 is occupied. Therefore, it is impossible to use C235,
C241, C244, C246, C247, C249, C252 and C254, input interruption (including delay interruption) pointers
I000 and I001 and SPD, ZRN, DSZR and DVIT instructions at the same time.
Input No. Contact on sequence program ON duration of input signal
