I want to show some alarms with the time when they have occurred. How can I display the time and date in a TD200C connected to a Siemens S7-224?

I know this is probably a stupid question and the answer is simple, but I'm not very expert.

Thank you.

 

Use the "READ_RTC" instruction to transfer the real time clock to a memory area, convert the data into the form you wish to view, and then embed that data into the alarm message.

 

The READ_RTC solution is good, but it may be tricky for non-experienced programmers.

There's a very simple free library for STEP7-MicroWIN that solves this, Nubitek_Free_Utils from http://www.nubitek.com.
It is a free block collection that includes a date/time to string converter. You can use it as a simple converter function of MicroWIN.

Here's the link:
