Operands:

S: Set-point value for driving the output device (Unit: hour)

D1: Current time being measured

D2: Output device

Explanations:

1.HOUR instruction drives the output device D2 when the measured current time D1 reaches the set-point value in S.

2.Range of S: K1~K32,767; unit: hour. Range of D1 in 16-bit instruction: K0~K32,767. Range of

D1 +1 (current time less than an hour): K0 ~K3,599; unit: second.

3.When the ON-time of the drive contact reaches the set-point value, output device will be ON. The instruction can be applied for controlling the working hours of machine or conducting preventive maintenance.

4.After output device is ON, the current time will still be measured in D1.

5.In 16-bit instruction, when the current time measured reaches the maximum 32,767 hours / 3,599 seconds, the timing will stop. To restart the timing, D1 and D1 + 1 have to be reset.

6.In 32-bit instruction, when the current time measured reaches the maximum 2,147,483,647 hours / 3,599 seconds, the timing will stop. To restart the timing, D1 ~ D1 + 2 have to be reset.

7.If operand S uses device F, only 16-bit instruction is available.

8.HOUR instruction can be used for four times in the program.

Program Example 1:

In 16-bit instruction, when X0 = ON, Y20 will be ON and the timing will start. When the timing reaches 100 hours, Y0 will be ON and D0 will record the current time measured (in hour). D1 will record the current time less than an hour (0 ~ 3,599; unit: second)..
