Function and operation explanation
1. 16-bit operation
The second unit data of the device specified by is converted into "hour, minute, second" unit, and the
result is stored in the device specified by .
For example, when 29011 seconds is specified, the operation is as follows.
2. 32-bit operation
The second unit data of the device specified by is converted into "hour, minute, second" unit, and the
result is stored in the device specified by .
For example, when 45325 seconds is specified, the operation is as follows.
Cautions
1) When handling 32-bit data in structured program, you cannot designate 16-bit device directly unlike the
simple project.
When handling 32-bit data, please use the label.
However, the 32-bit counter is a 32-bit long device, and 32-bit data can be specified directly.
When specifying the device, use the global label.
Error
In the following case, it is an operation error, and the error flag (M8067) is turned ON, and the error code is
stored in D8067.
1) When the data of the device specified by is out of the range. (Error code: K6706)
