11. Use of High-speed Counters (C235 to C255)
11.1 Outline
The high-speed counters can count the signals to the general-purpose input terminals to the main unit or to
the high-speed input special adapters (options).
These two types of counters differ in the maximum response frequency and type of input signals to be
counted.
→ For details, refer to Section 11.2.
• General-purpose input terminals of main unit
Signals from an open collector transistor output can be input to the counters. The counters can count
signals of up to 100kHz (1-phase).
• High-speed input special adapters
Signals from a differential line driver output can be input to the counters. The counters can count signals of
up to 200kHz (1-phase).
Cautions for high-speed input special adapters
Do not use the same input number for both the high-speed input special adapter terminal and the main unit
terminal.
• When wiring the input numbers assigned to a high-speed input special adapter, do not wire the same input
number in main unit.
• When not wiring the input numbers assigned to a high-speed input special adapter, the main unit’s input
terminals can be used as general inputs.
