Input Data Masking Function - Mitsubishi Electric NZ2GF2S-60IOLD8 User Manual

Input data masking function

This function calculates ON/OFF values in IO-Link (standard) mode according to the input process data.
With this function, changes in a specified bit of input process data can be detected easily.
Operation mode
This function is enabled only in IO-Link (standard) mode.
Description
Any bit from the first two bytes of input process data will be masked.
Set "Input Data Mask" depending on the process data structure of the IO-Link device used.
For information on IO-Link device process data structures, refer to the manual of the IO-Link device used.
If all input process data for the bits set to 1 in "Input Data Mask" is 1, CH Data masking results (RX0 to RX7) turn on.
If any of them is 0, CH Data masking results (RX0 to RX7) turn off.
• Input data masking results can be used with the input OFF delay function.
• When the bit segment function is enabled, input process data will be masked before bit segmentation. For
details on the bit segment function, refer to Bit segment function. ( Page 78 Bit segment function)
