Output HOLD function
This function holds output values when safety refresh data reception is interrupted.
Output HOLD occurrence
When detecting an interruption of safety refresh data reception, the output module with diagnostic functions holds the outputs
immediately before that interruption.
Output HOLD release
After an output HOLD occurs (safety refresh data reception is interrupted), when safety refresh data is received normally
within the time set with "Safety I/O Hold Time" in "CPU Parameter", the output HOLD will be released.
Safety I/O HOLD time exceeded error
When the time of holding outputs exceeds the time set with "Safety I/O Hold Time" in "CPU Parameter", a safety I/O HOLD
time exceeded error (error code: 1500H) will occur. And, all output values become OFF.
