Source device S1 occupies 2 consecutive data registers to store double-word data, starting with the designated device.

Destination device D1 occupies 3 consecutive data registers starting with the designated device.

Second data for source device S1 can be 0 through 4,294,967,295.

When the conversion result exceeds 65,535 hours 59 minutes 59 seconds, special internal relay M8003 (carry) is turned on. For example, when the

conversion result is 65,537 hours 0 minute 0 second, destination 1 stores 1 hour 0 minute 0 second, turning on special internal relay M8003 (carry).

Since the STOH instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

Examples: STOH

The following examples demonstrate the STOH instruction that will convert time data in seconds into hours, minutes, and seconds

and store the results to three consecutive data registers.
