Data-holding bits/link bits
256 data-holding bits of which 0, 64, or 128 can be designated as link bits
Timers/counters
SP10
16 total: one 1-ms timer and one analog timer (0.1 to 25.0 s) plus 10-ms timers, 100-ms timers,
reversible drum counters, and decrementing counters
SP16, SP20
16 total: one 1-ms timer and two analog timers (0.01 to 2.50 s, 0.1 to 25.0 s, or 1 to 250 s) plus
10-ms timers, 100-ms timers, reversible drum counters, a high-speed counter, and
decrementing counters
Memory protection
User program memory: RAM/EEPROM
Data-holding bits:
RAM (20 days at 25
°
C*), can be stored in EEPROM
*The power supply must be turned on for at least 10 minutes to charge battery. Length of
memory backup is reduced at higher temperatures.
Program check
Check for no END(01) instruction and for instruction errors when RUN mode is entered.
PC link
Up to 4 CPUs linkable via Link Adapter (sold separately)
