How to Convert PLC DL06 Timer K Value from Milliseconds to Minutes: Tips and Insights

Question:

Hello everyone, I recently began exploring the PLC DL06, and I've been diving into its features for about a week now. My current challenge is figuring out how to convert the K value in a timer from milliseconds to minutes. I’ve noticed discussions on other forums regarding changing K to a V register, and while I can access the V registers, I’m a bit confused about how to correctly use them, particularly the ranges of V4110 to V41103. Is there a specific register I should focus on, or do these numbers have a different significance? Any guidance would be greatly appreciated! Thank you! Best, Catait

The constant value K remains unchanged. In contrast, Vnn refers to a dynamic memory area that you can modify as needed. The maximum duration for timers is 999.9 seconds. According to the user manual, timers are designed to measure the duration of an event for a specified time. The single-input timer operates as long as the input signal remains active. Once the input signal transitions from on to off, the timer resets its current value back to zero. There are two types of timers available: one that measures tenths of a second with a maximum limit of 999.9 seconds, and another that measures hundredths of a second with a maximum limit of 99.99 seconds. Each timer is associated with a discrete bit that indicates whether the current timer value meets or exceeds the preset threshold. The timing diagram below illustrates the relationship among the timer input, the corresponding discrete bit, the current timer value, and the predetermined timer setting.

The manual linked above provides a comprehensive overview of timers. For detailed information, search for "Timer," "Counter," and "Shift Register Instructions" within this resource. Best regards,

In DirectSoft, when I require a minute timer, I utilize a 60-second timer to increment a counter. This method effectively transforms the counter into a reliable minute timer.
