Hi,

I was wondering if it's possible to adjust the CPU clock on a Siemens PLC from an iX application?

In the Developer I see a dataype = DATETIME, but I'm not sure if this has the same/ correct syntax..

The format of DATETIME is documented in section 4.14 of the iX Developer Reference Manual.

It requires 7 "16-bit" words/registers on the PLC to store the DATETIME. This is not Siemens specific and may require some PLC logic to read those values and update it's clock.
