19.6 General-purpose Input Functions
The FX5 PLC general-purpose inputs are explained below.
Outline of general-purpose input functions
For general-purpose inputs of the FX5 PLC, the input response time can be set by parameters.
Specifications of general-purpose inputs
Performance specifications
Input response times can be set to general-purpose inputs.
■Input response time setting
Input response times that can be set are shown below. The default value is 10 ms.
The value obtained by adding on the value of the hardware filter is the actual input response time.
■Hardware filter value
The delay times of the hardware filter on the CPU module is shown below.
The hardware filter value of I/O modules is 50 s when ON, and 150 s when OFF.
■Input response time setting units
The following table lists the units (1 point unit/8 point unit) that can be set for the input response time of each CPU module.
*1 When 1 point unit is set for the input response time using GX Works3, X41 to X47 operate with the input response time set to X40.
