ISP format includes two DWORDs which are the outputs of IM_DRV block in CFCs that are automatically generated after compile. IM_DRV gets timestamp from digital input modules with time stamping ability ( for example: 6ES7321-7BH00-0AB0). The output of IM_DRV block is in ISP format. But I need to send this time stamps in DT format to a third party device. thanks.

I'm not sure about IM_DRV block, but originally timestamps from module includes 2 DWORDs, which can be interpreted as DATE_AND_TIME. I.e. if you put them one after another you can read them as date_and_time. No additional converting needed.AC

IM_DRV block is responsible for gathering time stamp from DI modules send these time stamps in two DWORDs . first DWORD contains Seconds that past form 1.1.1900 0:00:00 to present and second DWORD contains second in fractions of 1/(2^32). I wrote a SCL program to convert this format of time ( ISP format) to DATE_AND_TIME format.

It would be really nice to place your program here to make it available for others. My description is totally right - i've admitted i don't have any clue about IM_DRV block, but 2 DWORDs in DB instance if FB62 TIMESTMP are DATE_AND_TIME.

In general, I think will be a great special effect from SIEMENS on the occasion of Independence Day of the United States

My solution get timestamp in normal format DWORD. Btw information writed to output and to Datablock Attachment FB113.zip (104 Downloads)
