Specifications Section 2-2
Function blocks Maximum number of function block definitions: 128
Maximum number of instances: 256
Languages usable in function block definitions: Ladder diagrams, structured text
(ST)
Instruction length 1 to 7 steps per instruction
Instructions Approx. 500 (function codes: 3 digits)
Instruction execution time Basic instructions: 0.10 µs min.
Special instructions: 0.15 µs min.
Common processing time 0.7 ms
Number of connectable Expansion
Units and Expansion I/O Units
7 Units (CP Series or CPM1A)
(There are restrictions on the Units that can be used in combination, however, based
on the total number of I/O words and the total current consumption.)
Max. number of I/O points 320 (40 built in + 40 per Expansion Unit/
Expansion I/O Unit × 7 Units)
300 (20 built in + 40 per Expansion Unit/
Expansion I/O Unit × 7 Units)
Number of connectable CJ-series
Units
2 Units
(CPU Bus Units or Special I/O Units only. Basic I/O Units cannot be used. A CP1W-
EXT01CJ Unit Adapter is required.)
Built-in
input termi-
nals (Func-
tions can be
assigned.)
Normal I/O 40 terminals
(24 inputs and 16 outputs)
20 (12 inputs and 8 outputs)
Note Aside from the above, 2 1-MHz
high-speed counter inputs and 2
1-MHz pulse outputs can be
added as special pulse I/O termi-
nals.
Interrupt
inputs
Direct
mode
8 inputs (Shared by the external interrupt
inputs (counter mode) and the quick-
response inputs.)
Rising or falling edge
Response time: 0.3 ms
6 inputs (Shared by the external interrupt
inputs (counter mode) and the quick-
response inputs.)
Rising or falling edge
Response time: 0.3 ms
Counter
mode
8 inputs, response frequency: 5 kHz
total, 16 bits
Incrementing counter or decrementing
counter
6 inputs, response frequency: 5 kHz
total, 16 bits
Incrementing counter or decrementing
counter
Quick-response
inputs
8 points (Min. input pulse width: 50 µs
max.)
6 points (Min. input pulse width: 50 µs
max.)
High-speed counters 4 inputs (24 VDC)
• Single phase (pulse plus direction, up/
down, increment), 100 kHz
• Differential phases (4×), 50 kHz
Value range: 32 bits, Linear mode or ring
mode
Interrupts: Target value comparison or
range comparison
2 inputs (24 VDC)
• Single phase (pulse plus direction, up/
down, increment), 100 kHz
• Differential phases (4×), 50 kHz
Value range: 32 bits, Linear mode or ring
mode
Interrupts: Target value comparison or
range comparison
Special
high-speed
counter ter-
minals
High-speed counters None 2 inputs (Line-driver inputs)
• Single phase (pulse plus direction, up/
down, increment), 1 MHz
• Differential phases (4×), 500 kHz
Value range: 32 bits, linear mode or ring
mode
Interrupts: Target value comparison or
range comparison
Note High-speed counter terminals are
line-driver inputs, so they cannot
be used as normal inputs.
