Where is this in S7-1200. I've checked the manual and searched the Help but no luck. Do I have to build my own? :/

Converting with T_Conv will convert my word to time but with this 1hz clockbit I don't get the right time. How do I do this?

Just T_ADD 1s to your run-time tag each pulse of your clock. Then the tag can be accessed by an HMI either directly or via day/hr/min/sec set of fields. Attachment RunTimer.jpg (2026 Downloads)

And How do I display this as day, hour, min and sec? When I use the tag in a I/O field in my HMI I only get seconds? The second you put the T_ADD in there, it runs every scan if you leave out the edge detection. Adds up very fast! It depends on the HMI. You'll have to look up how to display time on your HMI with the S7-1200. I've only used WinCC Flex HMI's so far, so I don't know if you can simply point to the S7-1200 PLC tag from the HMI. I think there are FAQs that describe what you want though. Just look around and you'll find it quickly.
