Input Response Time Selection (I/O Response Time) - Mitsubishi Electric MELSEC Q Series User Manual

11.1.4

Input response time selection (I/O response time)

The input response time can be changed for each Q series module.
(1) Applicable modules and setting contents
The following table shows the modules whose input response time can be changed and time options for them.
Module whose input response time can be changed
Input module
I/O combined module
High-speed input module
Interrupt module
The above Q series modules load external inputs within the specified input response time.
(2) Setting method
For this setting, use the following functions in Setting/monitoring tools for the C Controller module.
•
Project view  "Parameter"  "CCPU Parameter"  <<I/O assignment settings>>
 "Detailed Settings"  "I/O Response Time"
(3) Precautions
(a) When the input response time is reduced
Reducing the input response time value for high-speed response will make the module noise-sensitive.
Take into account the operating environment when setting the input response time.
(b) Timing when the setting takes effect
The input response time setting takes effect when:
• The C Controller system is powered on.
• The C Controller module is reset.
