The time base for a one-minute delay timer with a preset value of 600 in this PLC is 0.1 seconds. To determine the time base for a one-minute delay timer in a PLC (Programmable Logic Controller) with a preset value of 600, we need to consider the resolution or scaling factor of the timer instruction.
The time base refers to the time increment represented by each unit of the timer's preset value. In other words, it determines how the preset value corresponds to actual time.
Given that the preset value is 600 and we want to achieve a one-minute delay, we can set up the following equation:
Preset Value × Time Base = Time Delay
Substituting the values, we have:
600 × Time Base = 1 minute
To find the time base, we rearrange the equation:
Time Base = 1 minute / 600
Simplifying the calculation:
Time Base = 1/600 minute
Since there are 60 seconds in a minute, we can convert the time base to seconds:
Time Base = (1/600) minute × (60 seconds / 1 minute)
Time Base = 0.1 seconds
Therefore, the time base for a one-minute delay timer with a preset value of 600 in this PLC is 0.1 seconds.
