Page 40 Input Filtering Configurable Input The X8 Series PLC allow users to configure embedded digital I/O of DC inputs for high-speed or normal operation. Users can configure each input's response time. That is, it can be set the duration time that can recognize input signal form the PLC through a configurable input filter function.
Page 41 I/O Configuration 1-25 This function is used to process high-speed counters, latching inputs, and input interrupts. Note that the maximum filtered value is 16mS , and minimum is 5μS. Input filtering is configured using XGPC programming software which RS Automation is supply freely. 1.
Page 42 1-26 I/O Configuration Almost the X8 series PLC Analog modules such as X8-AI4AO2, X8-AI8, X8-AO4, X8-RT6 and X8-TC6 are able to config internal setting value. To use this function, the functions of analog modules, X8-AI4AO2 and X8-AI8, will be changed voltage Input or Current Input.

Page 44 1-28 I/O Configuration Input Channel Filtering The analog input channels use on-board signal conditioning to distinguish AC power line noise from normal variations in the input signal. Frequency components of the input signal at the filter frequency are rejected. Frequency components below the filter bandwidth (-3 dB frequency) are passed with under 3 dB of attenuation.
Page 45 X8-AO4 that supports 4-channels, 16-bit resolution. X8-AI4AO2 has 0~10V DC or 4~20mA output range. The X8 Series PLC have X8-AI4AO2 that supports 2-channels, 12-bit resolution and X8-AO4 that supports 4-channels, 16-bit resolution. X8-AI4AO2 has 0~10V DC or 4~20mA output range. X8-AO4, as high functional product, supports 0~5V, 0~10V, -5~5V and -10~10V voltage output, and 0~20mA and 4~20mA current output depending on the setting.
Page 46 ---------------- -x3000 0.457 V 65535 The X8 Series PLC provides the ability to configure latching input ports. A latching input is an input that captures a high-speed pulse signal and holds it for a single PLC scan. The pulse width that can be captured is dependent upon the input filtering selected for that input.
