I am a newcomer to System Platform and seeking guidance on how to read and write to a Time variable in a Siemens PLC. The variable I am working with is in the format of "T#10ms". Is there a way for System Platform to interpret this value as an Integer for reading, and convert it back to the format "T#..ms" when writing back in INT? Let me know if you have any insights or tips on this matter.
Siemens time variables are coded in 32 bits, making them suitable for a wide range of applications.
Utilize the TIME_TO_DINT and DINT_TO_TIME conversion functions for efficient data manipulation and optimization. These conversion blocks are essential for converting time data to integer format and vice versa, streamlining your programming processes.
The time variable is measured in milliseconds, with the format being Unsigned Double Word. Therefore, when you encounter "T#10ms," it actually represents "10," while "T#1h" translates to "3600000." This information is essential for programming and handling time-related tasks accurately.
The latest models of 1200/1500 PLCs boast a wider array of features beyond the commonly used TIME option. These include DTL, which organizes data in hours, minutes, seconds, etc., and LTIME, a 64-bit value that measures time in nanoseconds rather than milliseconds. Keep an eye out for these advanced options when upgrading your PLC system.
Hi there! Welcome to the world of System Platform. Working with time variables can be tricky, but it's definitely possible. For your case, if the PLC supports it, you could use an intermediate INT or DINT variable in the PLC to convert the time value into an integer. Then, read/write this integer value from/in the System Platform. Similarly, use another code block in the PLC to transform this INT back to the "T#..ms" format. This would maintain the encapsulation of the value while solving your problem of reading and converting back. Make sure to remember that similar to the DINT variable, the interpretation depends on the PLC program regarding how the integer is converted back to time. Hope this helps!
Absolutely, you can definitely work with Siemens PLC Time data type in System Platform. To read the "T#10ms" value as an integer, you will primarily want to use a calculation script within System Platform to interpret the Time data type into an INT data type. When it comes to writing back the value in the original format, you would effectively reverse this process. A good understanding of the PLC programming language is essential, particularly regarding 'Milliseconds to Time' or 'Time to Milliseconds' functions. There's a lot of tutorials and guides on this online that could be really helpful. Keep practicing and experimenting, and it will surely become clearer with time. Good luck!
Welcome to the community! To work with Time variables like "T#10ms" in System Platform and convert them to integers, you can use the appropriate functions or methods in your PLC programming environment. Generally, you would convert the Time to an integer representing milliseconds (like 10 for "T#10ms") for reading, and when writing back, you'll need to convert that integer back to the Time format by using the appropriate syntax. Some systems have built-in function blocks for this purpose, which can simplify the process significantly. It might also be helpful to check the documentation for the specific PLC you are using, as there may be unique functions for these conversions!
Welcome to the world of System Platform! To read a TIME variable formatted as "T#10ms" in Siemens PLCs and convert it to an Integer, you can use the TIME_TO_INT function, which will give you the total number of milliseconds as an integer. When you want to write back to the PLC, you can convert your integer back to the TIME format using the INT_TO_TIME function, ensuring it matches the "T#..ms" format. Just keep in mind to handle any conversions properly, especially when dealing with different time units like seconds or minutes. Good luck with your project!
Welcome to the world of System Platform! To work with time variables like "T#10ms", you'll need to handle the conversion process manually, as System Platform does not natively interpret time formats as integers. To read the "T#" value, you can extract the time in milliseconds, which can be done using a custom function to parse the string if you're dealing with it as text. For instance, you could create a conversion function that converts the time to an integer representing milliseconds. When writing back, you'll need to format that integer into the "T#" syntax. A simple way to achieve this is to append the time unit (for example, "T#" + yourIntegerValue + "ms") prior to sending the value back to the PLC. Good luck with your project!
