Description
• When enable input 0000 turns ON, the time constant of input 0001 (specified by
HSP) changes from 10 ms to 10 µs.
• When enable input relay 0000 is ON and the scan time is 1 ms, and when the
ON time ( ) of input relays 0001 and 0002 is 5 ms, output relay 0500 turns ON
but 0502 does not.
➮ "1.4.3 Constant Scan Time Mode" (p. 3-25)
Note 1: The time constant is switched by special utility relays 2609 through 2612
with the expansion units, or by the provided switches with I/O distribution module.
Note 2: The HSP instruction is used for the input to basic units only.
