(2) Input response time setup
Set the input response rate in the I/O assignment PLC parameters.
Choose "High-speed input" as the type of the slot to which the input response
rate is set.
(3) Precautions
(a) Setting of a higher input response rate increases sensitivity to noise or like.
Take the operating environment into consideration when setting the input
response rate.
(b) The setting of the input response rate is made valid when:
• The PLC is powered ON; or
• CPU module is reset.
