Counting
specification
Format
Automatic UP/DOWN (however, when on 1-phase 1-input mode, UP/DOWN is
determined by a PLC command or an input terminal.)
Range When 32-bit is specified : -2,147,483,648 to +2,147,483,647
When 16-bit is specified : 0 to 65,535 (upper limit can be user specified)
Comparison
Ty p e
Each output is set when the present value of the counter matches with the
compare value (which is transferred from the PLC), and is switched OFF by a
reset command from the PLC.
YH : Direct output processed by hardware.
YS : Software processed output with worst delay time of 300µs.
(Therefore, when the input frequency is 50 kHz, the
