Input/output Hold/Clear Setting Function
This function sets to hold or clear the last input or output values when the NZ2AW1GNAL is disconnected from a data link,
when the operating status of the CPU module is in STOP state, or when the operating status of the CPU module is in error
stop status.
If a moderate or major error occurs in the NZ2AW1GNAL, I/O will be turned off regardless of the input/output
hold/clear settings.
Input/output hold/clear settings and operation
The following table lists the setting items.
■
Output data hold/clear setting
The output of the NZ2AW1GNAL operates as follows depending on the setting value of "Output data hold/clear setting".
■ Word input data hold/clear setting when disconnected
