Setting up Hold / Clear (Address "10")
Buffer Memory Address "10"
This is used to keep analog output values as previous values or output an offset value when a PLC stops or an error occurs in it.
0 : Clear , 1 : Hold
To make hold/clear setup available, requesting to set up operation condition(Y0A) is to be set and reset.
Default value is clear.
As a set value is stored in EEPROM, the A/D module is operated as previously set value even though the power is on and off.
The combination of analog output statuses is as follows.
