Interrupt processing:
External interrupt
2 points (Response
time of 0.3 ms max.)
4 points (Response time of 0.3 ms max.)
Memory protection Maintains the contents of the HR, AR, Counter and Data Memory Areas.
Memory backup Flash memory: User program, data memory (Read only) (Non-battery powered stor-
age)
Super capacitor: Data memory (Read/Write), holding bits, auxiliary memory bits, count-
er (20-day storage at an ambient temperature of 25°C)
Self-diagnostic function CPU error (watchdog timer), memory errors, I/O bus errors
Program check No END instruction programming errors (constantly checked during operation)
Pulse output 1 point: 2 kHz
High-speed counter 1 point: Single phase at 5 kHz or two-phase at 2.5 kHz (linear counting method)
Incremental mode: 0 to 65535 (16-bit)
Decremental mode:–32767 to 32767 (16-bit)
1 point: Single phase at 5 kHz or two-phase at 2.5 kHz (linear counting method)
Incremental mode: 0 to 65535 (16-bit)
Decremental mode:–32767 to 32767 (16-bit)
Quick-response inputs Together with the external interrupt input (minimum pulse width of 0.2 ms)
Input time constant Can be set at 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, 32 ms, 64 ms, or 128 ms.
Analog settings 2 points: (0 to 200)
Note: Bits that are not used for the I/O bits can be used as work bits.
