File Size - Mitsubishi Electric MELSEC IQ-R series Reference Manual

Time (hour, minute, second)
Represent the hour, minute, second with 16-bit value.
• Hour: The binary value is represented with bits 11 to 15.
• Minute: The binary value is represented with bits 5 to 10.
• Second: The binary value divided by 2 is represented with bits 0 to 4.
