*1. If device numbers are not consecutive, refer to program example 3 on the next page.
*2. When a non-keep type data register is used for D8158, the current value of the data register becomes
"0" when the PLC is stopped. As a result, the device type displayed as "D" becomes invalid, and
the operator functions become valid.
Use a keep type data register as shown above for making invalid the operator functions.
*3. When a keep type auxiliary relay is used for D8159, initialize it using the FNC 40 (ZRST) instruction,
etc.
